Collective charge transport processes in condensed matter and biological systems

Collective charge transport processes occur in inanimate condensed matter systems as well as biological macro-molecules. Physical models can provide insight into both types of systems when there is transport of charges. A large body of experimental evidence suggests that the decay of the false vacuum, accompanied by quantum pair creation of soliton domain walls, can occur in a variety of condensed matter systems. A macroscopic quantum charge transport of density waves by pair creation of soliton domain walls is studied. It is discussed under theoretical arguments for the existence of high-temperature collective quantum phenomena. Here a macroscopic Coulomb blockade model is utilized to develop and study a novel soliton tunneling transistor, which represents a macroscopic version of the single electron transistor. The electron transport is reviewed via quantum tunneling in proteins and a theoretical junction model of the mitochondrial electron transport chain is proposed. The interaction of the mitochondrial electron transport with oscillatory electric field is considered; therefore, the numerical predictions are compared with the results obtained by experimental measurements of the harmonics induced in the mitochondria of yeast cells.
