A Quantum Fluctuation Theorem

摘要

We consider a quantum system strongly driven by forces that are periodic in time. The theorem concerns the probability P(e)P(e) of observing a given energy change ee after a number of cycles. If the system is thermostated by a (quantum) thermal bath, ee is the total amount of energy transferred to the bath, while for an isolated system ee is the increase in energy of the system itself. Then, we show that P(e)/P(e)=eβeP(e)/P(-e)=e^{\beta e}, a parameter-free, model-independent relation.
