Energy transduction in periodically driven non-Hermitian systems
arXiv:cond-mat/0009214 · doi:10.1103/PhysRevLett.85.3995
Abstract
We show a new mechanism to extract energy from non-equilibrium fluctuations typical of periodically driven non-Hermitian systems. The transduction of energy between the driving force and the system is revealed by an \emph{anomalous} behavior of the susceptibility, leading to a diminution of the dissipated power and consequently to an improvement of the transport properties. The general framework is illustrated by the analysis of some relevant cases.
