The dynamics of quasiparticles in a toy model of the KcsA biological ion channel

EasyChair Preprint no. 966

Abstract

We study the highly-concerted motion of ions in a narrow biological ion channel (KcsA) by considering the notion of a quasiparticle, with specific focus on the transition process. Namely, we show that the ion entering or exiting the channel is correlated with the position of the quasiparticle. This result is of importance in the rate theories of ion conduction through narrow channels and artificial nanopores.

Keyphrases: Brownian Dynamics, differential Chapman-Kolmogorov equation, effective potential, highly-correlated ionic motion, ion channel, quasiparticle, statistical physics, transition process
