论文摘要
当两个有限储层之间的潜在偏差驱动时,跨量子系统的粒子电流从初始载荷从初始载荷到相干演变而来,然后是亚稳态相,最终在平衡时消失了。我们制定了一个理论,该理论充分说明了相关的,不同的时间尺度,并确定了衰减速率的参数依赖性,该衰减速率最终控制了趋于平衡的收敛性。我们的形式主义保证了系统中流动的宏观和内部电流之间的总颗粒数量和基本一致性。我们此外,在产生的电导率上建立了费尔米金或骨化粒子特征的明显烙印。
When driven by a potential bias between two finite reservoirs, the particle current across a quantum system evolves from an initial loading through a coherent, followed by a metastable phase, and ultimately fades away upon equilibration. We formulate a theory which fully accounts for the associated, distinct time scales, and identifies the parameter dependence of the decay rate which ultimately controls the convergence towards equilibrium. Our formalism guarantees total particle number conservation and fundamental consistency between macroscopic and internal currents flowing in the system. We furthermore establish a clear imprint of the fermionic or bosonic particle character on the resulting conductance.
