HEAT BATH COUPLING EFFECTS ON INTERACTION BETWEEN FROHLICH VIBRATION SYSTEMS

The energy supplied to the Frohlich vibration system in a living cell may condense in certain normal modes provided the coupling of the vibr ation system with a heat bath is nonlinear. The strong coupling of a c oherent vibration system with a heat bath causes reduced energy conden sation; high frequency modes are not excited and the energy condensed in the lowest frequency mode is smaller than the energy condensed in a system with weak coupling. The vibrations are polar and generate an e lectromagnetic field. The electromagnetic field mediates a long range interaction between the Frohlich vibration systems; the interaction de pends on the intensity of the generated electromagnetic field, and, th erefore, on the energy condensed in the vibration system. The systems with strong coupling with a heat bath have weak interaction forces, wh ich may be attractive as well as repulsive. The effect of coupling wit h a heat bath on interaction between the Frohlich systems is a new con tribution of this paper. The coherent vibration systems are assumed to be excited in protein molecules in cellular membranes. Protein phosph orylation may cause the strong Coulomb coupling of vibration systems w ith a heat bath and may have a fundamental effect on energy condensati on.
