Editing Geometric phase (section)

=== Stochastic pump effect ===

A stochastic pump is a classical stochastic system that responds with nonzero, on average, currents to periodic changes of parameters.
The stochastic pump effect can be interpreted in terms of a geometric phase in evolution of the moment generating function of stochastic currents.<ref name="sinitsyn-07epl">{{cite journal|title=The Berry phase and the pump flux in stochastic chemical kinetics|author1=N.
