Discrete changes of current statistics in periodically driven stochastic systems

Abstract
We demonstrate that the counting statistics of currents in periodically driven ergodic stochastic systems can show sharp changes of some of its properties in response to continuous changes of the driving protocol. To describe this effect, we introduce a new topological phase factor in evolution of the moment generating function which is akin to the topological geometric phase in evolution of a periodically driven quantum mechanical system with time-reversal symmetry. This phase leads to the prediction of a sign change for the difference of the probabilities to find even and odd number particles transferred in a stochastic system in response to cyclic evolution of control parameters. The driving protocols that lead to such a sign change should enclose specific degeneracy points in the space of control parameters. The relation between topology of the paths in the control parameter space and the sign changes can be described in terms of the first Stiefel-Whitney class.
