Reversible stochastic pump currents in interacting nanoscale conductors

TL;DR

This paper discusses how the geometric phase causes reversible pump currents in classical stochastic systems and proposes that these can be observed experimentally using electronic setups similar to recent experiments.

Contribution

It demonstrates the potential to observe geometric phase effects in nanoscale conductors through experimental electronic setups.

Findings

Geometric phase induces reversible pump currents.

Experimental observation is feasible with current electronic technology.

Connects classical stochastic kinetics with quantum geometric effects.

Abstract

I argue that the geometric phase, responsible for reversible pump currents in classical stochastic kinetics, can be observed experimentally with an electronic setup, similar to the ones reported recently in [Phys. Rev. Lett. 96,076605 (2006)] and [Nature Physics 3, 243 - 247 (2007)].
