Electromagnetism & Fröhlich Modes
Collective large-scale vibrational modes that imply microwave absorption and emission

Pablo Andueza Munduate

Fröhlich predicted that biological systems can generate collective vibrational modes in the GHz frequency range, based on the Bose condensation to the lowest excitation of a single mode, of the energy supplied. It is proposed that cell membranes and microtubules are targets of this phenomena, this entails, because of their dipolar properties, electromagnetic emisions and absortions in the GHz range. ...

As described in [1] Fröhlich effect consists in that

" Provided the energy supply is sufficiently large compared with the energy loss, the system attains a stationary state in which the energy that feeds the polar modes is channelled into the modes with the lowest frequencies. The latter largely increase their populations at the expenses of the other higher-in-frequency modes, in a way reminiscent of a Bose-Einstein condensation."

Those synchronous large-scale collective oscillations imply microwave emissions.

Because mitocondria generates a strong electric field is believed that given the fact that mitochondria are aligned in the vicinity of microtubules, the latter are immersed in this field and because both the tubulin heterodimers and microtubules possess strong electric dipoles that interact with the field it can promotes the nonlinear properties represented in the Fröhlich model, so microtubules are a good candidates.

The reality is that Fröhlich modes are found in a protein structural network, as proved by Ludholm et al. [2]:

" To that end, we used X-ray crystallography combined with THz radiation to visualize structural changes associated with low-frequency collective vibrations induced in lysozyme protein crystals by irradiation with 0.4 THz radiation and detected steady state structural changes that are sustained for micro- to milli-seconds, which is 3–6 orders of magnitude longer than expected if the structural changes would be due to a redistribution of vibrations upon terahertz absorption following Boltzmann's distribution. Our analyses show that the long lifetime of these structural changes can only be explained by Fröhlich condensation. Our results thus provide the first strong evidence for the occurrence of Fröhlich condensation in a protein structural network and indicate that macroscopic quantum effects may manifest in biological systems."

There are varios propositions to integrate those non-linear phenomena with other non-linear electromagnetic emission, like those in the optic range (including near-infrared and ultraviolet) tened biophotons or ultraweak photon emissions *(UPE) as can be seen in [3,4]. Swain [4] wrote:

" ... the factor of 400 or so derived above is about what one would want to get from Fröhlich frequencies in the microwave region to visible Popp photons ... There is even a degree of reversibility in the system and one can imagine coupling what we have so-far considered as an outgoing photon mode to an external visible photon which could in turn be down-converted into Fröhlich photons. This offers the possibility of affecting Fröhlich dynamics inside a cell via visible photons injected from outside, as well as to the possibility of a long range coupling of internal cellular Fröhlich dynamics between cells via visible Popp photons.This also suggests new experiments looking for microwave responses to visible stimulation and vice-versa."

There is a great section dedicated to biophotons in this site [5] but this text will continue describing some other interesting experimental findings and propositions.

Preto et al. [6] propose that given the fact that experimental evidence for the existence of collective excitations within macromolecules of biological relevance is available for proteins and forpolynucleotides (DNA and RNA), with a coherent collective oscillation modes of the whole molecule (protein or DNA) or of a substantial fraction of its atoms, a mechanism such as Fröhlich condensation (or more generally dynamic synchronizations) between molecules turns out to be effectively active in biological systems, implying long-range attractive interactions between biomolecules provided that the latter share common frequencies in their vibration spectra.

Taking in consideration the above mentioned mitochondria-microtubule EM relation, Šrobár [7] proposed that its disruption provoke cancer.

" The computed results show that simultaneous presence of both sufficient metabolic pumping and adequately elevated static electric field is necessary for the full unfolding of the hallmark properties of the Fröhlich model. It is suggested that cancer-related mitochondrial dysfunction leading to metabolic transformation has additional adverse effect mediated by diminution of static fields which in turn reduces the nonlinear processes in the Fröhlich systems, essential for energy condensation in the fundamental mode."

E. Anton et al. [8] wrote:

" .. due to the interactions between bose condensed quasi-particles, it seems that periodical transformations of the phonons into photons and vice versa take place. If this interaction is strong, both photons and phonons can no longer be considered independent. In this way, these two excited states coupled constitute a mixture of phononi and photons called polaritons [15]. When the milimeter photons and phonons are in the bose-condensed state, the formed polaritons will be in the same state."

and proposed that fröhlich condensate is the medium by which millimeter wave therapies act on biosystems.
