Title: The transient regime in Frohlich's condensation phenomenon in biosystems
Author: Tenan, MA

Abstract: We consider the emergence of the so-called Frohlich's effect in a biosystem, a phenomenon consisting of the condensation of excitations in the polar vibrational modes lying at the bottom of these modes' frequency spectrum. This complex behavior of the system, which seems to have relevance in bioenergetics, may arise in open biomaterial, which is governed by nonlinear kinetic equations, and when under the action of a pumping source of metabolic energy. We analyze here in detail the dynamics of (i) the transient stage before the establishment of a steady state and (ii) the relaxation to the original thermodynamic equilibrium state after the pumping source is turned off.
