强耦合非马尔可夫体系中的非平衡量子输运系数和全计数统计的瞬态动力学

Non-equilibrium quantum transport coefficients and the transient dynamics of full counting statistics in the strong coupling and non-Markovian regimes

Javier Cerrillo, Maximilian Buser, Tobias Brandes

摘要:

量子系统的非平衡输运性质最近在测量瞬态和稳态非平衡输运动力学的所谓的全计数实验中的许多平台中变得实验可访问。我们表明,测量反作用的效果可以利用获得相关的输运系数。这种关系是普遍的,但在强耦合到非马尔可夫环境下的开放量子系统的瞬态动力学中变得最为明显。为了探索这一制度,一个新的模拟方法的非马尔可夫,强耦合运输设置的全计数统计的产生已被开发,表示在运动方程的层次。有了这个工具,我们可以访问相关的制度,并实例化我们的建议,通过几个水平系统连接的两个浴之间的能量电导的研究。

英文摘要:

Non-equilibrium transport properties of quantum systems have recently become experimentally accessible in a number of platforms in so-called full-counting experiments that measure transient and steady state non-equilibrium transport dynamics. We show that the effect of the measurement back-action can be exploited to gain access to relevant transport coefficients. This relationship is general, but becomes most conspicuous in the transient dynamics of open quantum systems understrong coupling to non-Markovian environments. In order to explore this regime, a new simulation method for the generation of full counting statistics of non-Markovian, strong-coupling transport settings has been developed that is expressed in terms of a hierarchy of equations of motion. With this tool we gain access to the relevant regime and instantiate our proposal with the study of energetic conductance between two baths connected via a few level system.
