Fractional Quantum Hall effect in TGD frameworkThe generalization of the imbedding space discussed in previous posting allows to understand fractional quantum Hall effect (see this and this). The formula for the quantized Hall conductance is given by σ= ν× e^{2}/h,ν=m/n. Series of fractions in ν=1/3, 2/5 3/7, 4/9, 5/11, 6/13, 7/15..., 2/3, 3/5, 4/7 5/9, 6/11, 7/13..., 5/3, 8/5, 11/7, 14/9... 4/3 7/5, 10/7, 13/9... , 1/5, 2/9, 3/13..., 2/7 3/11..., 1/7.. with odd denominator have bee observed as are also ν=1/2 and ν=5/2 state with even denominator. The model of Laughlin [Laughlin] cannot explain all aspects of FQHE. The best existing model proposed originally by Jain [Jain] is based on composite fermions resulting as bound states of electron and even number of magnetic flux quanta. Electrons remain integer charged but due to the effective magnetic field electrons appear to have fractional charges. Composite fermion picture predicts all the observed fractions and also their relative intensities and the order in which they appear as the quality of sample improves. I have considered earlier a possible TGD based model of FQHE not involving hierarchy of Planck constants. The generalization of the notion of imbedding space suggests the interpretation of these states in terms of fractionized charge and electron number.

The photons emitted in the dropping of protons and electrons to larger spacetime sheets as signature of manysheeted spacetimeThe dropping of particle to a larger spacetime sheet liberates energy, which is the difference of the energies of the particle at two spacetime sheets. If the interaction energy of the particle with the matter at spacetime sheet can be neglected the energy is just the difference of zero point kinetic energies. This energy depends on the details of the geometry of the spacetime sheet. Assuming padic length scale hypothesis the general formula for the zero point kinetic energy can be written as E(k)= x× E_{0}(k) , E_{0}(k)=(3/2)×(π^{2}/mL^{2}(k)) . Here x is a numerical factor taking into account the geometry of the spacetime sheet and equals to x=1 for cubic geometry. The liberated zero point kinetic energy in the case that the particle drops to a spacetime sheet labelled by k_{f}=k+Δ k with same value of x is ΔE(k,Δk)=x× E_{0}(k)×(12^{Δ k}) . The transitions are seen as discrete lines for some resolution Δ k≤Δ k_{max}. At the limit k→ ∞ transitions give rise to a quasicontinuous band. The photon energy for k→ ∞ transition is same as the energy from k1→ k transition, which brings in additional option to the model building. For a proton dropping from the atomic spacetime sheet k=137 to very large spacetime sheet (Δ k→ ∞) one has ΔE(k)= E(k)≈ x× .5 eV. Since the ratio of electron and proton masses is m_{p}/m_{e}≈ .94× 2^{11}, the dropping of electron from spacetime sheet k_{e}=k_{p}+11 liberates zero point kinetic energy which is by a factor .9196 smaller. For k_{p}=137 one would have k_{e}= 148. This energy corresponds to the metabolic energy currency of living systems and the idea is that the differences of zero point kinetic energies define universal metabolic energy currencies present already in the metabolism of prebiotic systems. In the following fit electron's zero point kinetic energy will be taken to be E_{0}(148)=.5 eV so that for proton the zero point kinetic energy would be E_{0}(137)=.544 eV. The hypothesis predicts the existence of anomalous lines in the spectrum of infrared photons. Also fractally scaled up and scaled down variants of these lines obtained by scaling by powers of 2 are predicted. The wavelength corresponding to .5 eV photon would be λ= 2.48 μm. These lines should be detectable both in laboratory and astrophysical systems and might even serve as a signature for a primitive metabolism. One can also consider dropping of Cooper pairs in which case zero point kinetic energy is scaled down by a factor of 1/2. Interestingly, the spectrum of diffuse interstellar medium exhibits three poorly understood structures: Unidentified Infrared Bands (UIBs), Diffuse Interstellar Bands (DIBs), and Extended Red Emission (ERE) allowing an interpretation in terms of dropping of protons or electrons (or their Cooper pairs) to larger spacetime sheets. The model also suggests the interpretation of biophotons in terms of generalizes EREs. 1. Unidentified Infrared Bands Unidentified infrared bands (UIBs) contain strong bands at λ=3.3, 6.2, 11.3 microns. The best fit for the values of k and Δk assuming dropping of either electron or proton are given by the following table. The last row of the table gives the ratio of predicted photon energy to the energy characterizing the band and assuming x=1 and E_{0}(148,e)=.5 eV. Discrepancies are below 8 per cent. Also the dropping of protonic Cooper pair from k=137 spacetime sheet could reproduce the line Δ E= .2 eV. The fit is quite satisfactory although there is of course the uncertainty related to the geometric parameter x. Table 1 . According to this article, UIBs are detected along a large number of interstellar sightlines covering a wide range of excitation conditions. Recent laboratory IR spectra of neutral and positively charged polycyclic aromatic hydrocarbons (PAHs) has been successfully used by Allamandola to model the observed UIBs (L. J. Allamandola, M. P. Bernstein, S.A. Sandford (1997), in Astronomical and biochemical origins and the search for life in the universe, Ed. C.B Cosmovici, S. Bowyer, D. Wertheimer, pp. 2347, Editrice Compositori, Bologna.). It is believed that PAHs are produced in reactions involving photosynthesis and are regarded as predecessors of biotic life (see this). This would conform with the presence of metabolic energy quanta. DNA sugar bone, some aminoacids, and various hallucinogens involve 5 and 6cycles and the proposal is that these cycles involve free electron pairs, which possess Planck constant hbar= n×hbar_{0}, n=5, 6. These free electron pairs would explain the anomalous conductivity of DNA and would be an essential characteristic of living matter. The emergence of n=5,6 levels could be seen as the first step in the prebiotic evolution. 2. Diffuse Interstellar Bands There are diffuse interstellar bands (DIBs) at wavelengths 578.0 and 579.7 nanometers and also at 628.4, 661.4 and 443.0 nm. The 443.0 nm DIB is particularly broad at about 1.2 nm across  typical intrinsic stellar absorption features are 0.1 nm (see this). The following table proposes a possible identification of these lines in terms of differences of zero point kinetic energies. Also now the best fit has errors below 7 per cent. Table 2 . The peak wavelengths in chlorophyll and photosynthesis are around 650 nm and 450 nm and could correspond to second and third row of the table. 3. The Extended Red Emission The Extended Red Emission (ERE) (see this and this) is a broad unstructured emission band with width about 80 nm and located between 540 and 900 nm. The large variety of peak wavelength of the band is its characteristic feature. In majority of cases the peak is observed in the range 650750 nm but also the range 610750 nm appears. ERE has been observed in a wide variety of dusty astronomical environments. The necessary conditions for its appearance is illumination by UV photons with energies E≥ 7.25 eV from source with T≥ 10^{4} K. The position of the peak depends on the distance from the source . According to the current interpretation attributes ERE to a luminescence originating from some dust component of the ISM, powered by UV/visible photons. Various carbonaceous compounds seem to provide a good fit to the observational constraints. However, the real nature of ERE is still unknown since most candidates seem to be unable to simultaneously match the spectral distribution of ERE and the required photon conversion efficiency. a) Consider first the band 650750 nm appearing in the majority of cases. The most natural interpretation is that the lower end of the band corresponds to the zero point kinetic energy of electron at k=135+11=146=2× 73 spacetime sheet. This would mean that the lines would accumulate near 650 nm and obey the period doubling formula [(λ(k)λ(∞)]/λ(∞)= 2^{k}/(12^{k}) . By the estimate of Table 2 the lower end should correspond to λ=628.4 nm with a correction factor x< 1 reducing the zero point kinetic energy. The reduction would be smaller than 4 per cent. Δk=3 transition would correspond to 744 nm quite near to the upper end of the band. For Δk=2 transition one has λ=867 nm not to far from the upper end 900 nm. Δk=1 corresponds to 1.3 μm. b) For proton with k=135=146 the energy band would shift by the factor 2^{11}m_{e}/m_{p}≈ 1.087 giving the range (598,690) nm. c) The variation for the position of the peak can be understood if the charged particles at the smaller spacetime sheet can have excess energy liberated in the dropping to the larger spacetime sheet. This excess energy would determine the position of the lower end of the band in the range (540,650) nm. d) One should also understand the role of UV photons. UV photon with energy E≥ 8 eV could kick electrons from large spacetime sheets to k=144=1464 spacetime sheet where they have zero point kinetic energy of 8 eV plus possible additional energy. One possibility is that these electrons drop first to k=145 by the emission of ≈ 4 eV UV photon and then to k=144 by the emission ≈ 2 eV photon corresponding to 650 nm line. The further dropping to larger spacetime sheets would produce besides this line also the lines with longer wavelengths in the band. 4. Could UV photons have some metabolic role? The correlation between UV photons and ERE brings in mind the vision that high temperature plasmoids are primitive lifeforms possibly having universal metabolic energy quanta in UV range. One can imagine that the development of chemical energy storage mechanisms has made it possible to use visible light from Sun as a source of metabolic energy and get rid of UV quanta having disastrous biological effects. Ozone layer shields out most of UV light and also air absorbs the UV light below wavelength 200 nm, which justifies the term vacuum UV (VUV) for this range. Table 3 .
From Table 3 one finds that Δk >2 electronic transitions cascading to 8 eV (155 nm) by period doubling belong to vacuum UV (VUV) absorbed by air. The lines 310 nm and 207 nm corresponding to Δk=1 and Δk=2 could however define frequency windows since these lines need not correspond to any atomic or molecular electronic transitions. In the solar photosphere the temperature is about 5800 K, roughly half of the minimum temperature 10^{4} K needed to generate the UV radiation inducing ERE in interstellar dust. Solar corona however has temperature of about 10^{6} K, which corresponds to a thermal energy of order 100 eV and the UV radiation from corona at above mentioned discrete frequencies resulting in dropping of electrons could serve as a metabolic energy source for prebiotics in the interstellar space. This raises obvious questions. Should the stellar sources inducing ERE possess also corona? Could 4 eV and 6 eV UV photons from the solar corona serve as a source of metabolic energy for some primitive organisms like blue algae? 5. What about biophotons? Also the wave length of biophotons are in the range of visible photons. Their spectrum is claimed to be featureless, which would suggest that identification in terms of photons resulting in dropping of electrons and protons to larger spacetime sheets might not make sense. The variation of the geometric shape of spacetime sheets, the possibility of surplus energy, and the clustering of the transition lines around the lower end of wave length spectrum might however give rise to effectively featureless spectrum. For details see the chapter About the New Physics Behind Qualia.

Could one demonstrate the existence of large Planck constant photons using ordinary camera or even bare eyes?If ordinary light sources generate also dark photons with same energy but with scaled up wavelength, this might have effects detectable with camera and even with bare eyes. In the following I consider in a rather lighthearted and speculative spirit two possible effects of this kind appearing in both visual perception and in photos. For crackpotters possibly present in the audience I want to make clear that I love to play with ideas to see whether they work or not, and that I am ready to accept some convincing mundane explanation of these effects and I would be happy to hear about this kind of explanations. I was not able to find any such explanation from Wikipedia using words like camera, digital camera, lense, aberrations.. Why light from an intense light source seems to decompose into rays? If one also assumes that ordinary radiation fields decompose in TGD Universe into topological light rays ("massless extremals", MEs) even stronger predictions follow. If Planck constant equals to hbar= q×hbar_{0}, q=n_{a}/n_{b}, MEs should possess Z_{na} as an exact discrete symmetry group acting as rotations along the direction of propagation for the induced gauge fields inside ME. The structure of MEs should somewhat realize this symmetry and one possibility is that MEs has a wheel like structure decomposing into radial spokes with angular distance Δφ= 2π/n_{a} related by the symmetries in question. This brings strongly in mind phenomenon which everyone can observe anytime: the light from a bright source decomposes into radial rays as if one were seeing the profile of the light rays emitted in a plane orthogonal to the line connecting eye and the light source. The effect is especially strong if eyes are stirred. Could this apparent decomposition to light rays reflect directly the structure of dark MEs and could one deduce the value of n_{a} by just counting the number of rays in camera picture, where the phenomenon turned to be also visible? Note that the size of these wheel like MEs would be macroscopic and diffractive effects do not seem to be involved. The simplest assumption is that most of photons giving rise to the wheel like appearance are transformed to ordinary photons before their detection. The discussions about this led to a little experimentation with camera at the summer cottage of my friend Samppa Pentikäinen, quite a magician in technical affairs. When I mentioned the decomposition of light from an intense light source to rays at the level of visual percept and wondered whether the same occurs also in camera, Samppa decided to take photos with a digi camera directed to Sun. The effect occurred also in this case and might correspond to decomposition to MEs with various values of n_{a} but with same quantization axis so that the effect is not smoothed out. What was interesting was the presence of some stronger almost vertical "rays" located symmetrically near the vertical axis of the camera. The shutter mechanism determining the exposure time is based on the opening of the first shutter followed by closing a second shutter after the exposure time so that every point of sensor receives input for equally long time. The area of the region determining input is bounded by a vertical line. If macroscopic MEs are involved, the contribution of vertical rays is either nothing or all unlike that of other rays and this might somehow explain why their contribution is enhanced. Addition: I learned from Samppa that the shutter mechanism is unnecessary in digi cameras since the time for the reset of sensors is what matters. Something in the geometry of the camera or in the reset mechanism must select vertical direction in a preferred position. For instance, the outer "aperture" of the camera had the geometry of a flattened square. Anomalous diffraction of dark photons Second prediction is the possibility of diffractive effects in length scales where they should not occur. A good example is the diffraction of light coming from a small aperature of radius d. The diffraction pattern is determined by the Bessel function J_{1}(x), x=kdsin(θ), k= 2π/λ. There is a strong light spot in the center and light rings around whose radii increase in size as the distance of the screen from the aperture increases. Dark rings correspond to the zeros of J_{1}(x) at x=x_{n} and the following scaling law for the nodes holds true sin(θ_{n})= x_{n}λ/2πd. For very small wavelengths the central spot is almost pointlike and contains most light intensity. If photons of visible light correspond to large Planck constant hbar= q× hbar_{0} transformed to ordinary photons in the detector (say camera film or eye), their wavelength is scaled by q and one has sin(θ_{n})→ q× sin(θ_{n}) The size of the diffraction pattern for visible light is scaled up by q. This effect might make it possible to detect dark photons with energies of visible photons and possibly present in the ordinary light.

Burning salt water with radio waves and large Planck constantThis morning my friend Samuli Penttinen send an email telling about strange discovery by engineer John Kanzius: salt water in the test tube radiated by radiowaves at harmonics of a frequency f=13.56 MHz burns. Temperatures about 1500 K which correspond to .15 eV energy have been reported. You can radiate also hand but nothing happens. The orginal discovery of Kanzius was the finding that radio waves could be used to cure cancer by destroying the cancer cells. The proposal is that this effect might provide new energy source by liberating chemical emergy in an exceptionally effective manner. The power is about 200 W so that the power used could explain the effect if it is absorbed in resonance like manner by salt water. The energies of photons involved are very small, multiples of 5.6× 10^{8} eV and their effect should be very small since it is difficult to imagine what resonant molecular transition could cause the effect. This leads to the question whether the radio wave beam could contain a considerable fraction of dark photons for which Planck constant is larger so that the energy of photons is much larger. The underlying mechanism would be phase transition of dark photons with large Planck constant to ordinary photons with shorter wavelength coupling resonantly to some molecular degrees of freedom and inducing the heating. Microwave oven of course comes in mind immediately.
Recall that one of the empirical motivations for the hierarchy of Planck constants came from the observed quantum like effects of ELF em fields at EEG frequencies on vertebrate brain and also from the correlation of EEG with brain function and contents of consciousness difficult to understand since the energies of EEG photons are ridiculously small and should be masked by thermal noise. In TGD based model of EEG (actually fractal hierarchy of EEGs) the values hbar/hbar_{0} =2^{k11}, k=1,2,3,..., of Planck constant are in a preferred role. More generally, powers of two of a given value of Planck constant are preferred, which is also in accordance with padic length scale hypothesis. For details see the chapter Dark Nuclear Physics and Condensed Matter.
