开放量子系统中电流的涨落定理

Fluctuation theorem for currents in open quantum systems

David Andrieux, Pierre Gaspard, Takaaki Monnai, Shuichi Tasaki

摘要:

建立了一个量子力学框架,描述了在含时驱动下开放系统中粒子在库间流动的全计数统计。得到一个对称关系,这是微观可逆性的结果的概率的非平衡功和转移的粒子和能量之间的水库。在适当的长时间范围内,对称关系导出了两个库之间电流的稳态量子涨落定理。在此基础上,推导出将Onsager-Casimir互易关系推广到非线性响应系数的关系式。

英文摘要:

A quantum-mechanical framework is set up to describe the full counting statistics of particles flowing between reservoirs in an open system under time-dependent driving. A symmetry relation is obtained which is the consequence of microreversibility for the probability of the nonequilibrium work and the transfer of particles and energy between the reservoirs. In some appropriate long-time limit, the symmetry relation leads to a steady-state quantum fluctuation theorem for the currents between the reservoirs. On this basis, relationships are deduced which extend the Onsager-Casimir reciprocity relations to the nonlinear response coefficients.
