Abstract
En 中文
We theoretically study the entropy production and the work extracted from a system connected to two reservoirs by periodic modulations of the electrochemical potentials of the reservoirs and the parameter of a system Hamiltonian under isothermal conditions. We find that the modulation of the parameters can drive a geometric state, which is away from a nonequilibrium steady state (NESS). Using this property, we construct a demon in which the entropy production during the first one-cycle is negative such that we can extract the work if we start from the NESS without parameter modulations. We use the Anderson model to implement the demon in a realistic situation.
