论文摘要
我们开发了“双重性方法”,该方法已被广泛研究用于经典的传输模型,即与热`lindbladian'浴的量子系统接触。该方法(a)将原始模型映射到一个较简单的模型中,仅包含几个粒子,(b)表明,任何具有通用浴的动态过程都可以映射到具有平衡浴缸的一个。我们通过研究特定模型的研究来体现这一点:[D.中引入的量子对称排除过程伯纳德(T. Jin),物理。莱特牧师。 123,080601(2019)]。与经典案例一样,通过考虑问题的动力对称性,整个结构变得可理解。
We develop the `duality approach', that has been extensively studied for classical models of transport, for quantum systems in contact with a thermal `Lindbladian' bath. The method provides (a) a mapping of the original model to a simpler one, containing only a few particles and (b) shows that any dynamic process of this kind with generic baths may be mapped onto one with equilibrium baths. We exemplify this through the study of a particular model: the quantum symmetric exclusion process introduced in [D. Bernard, T. Jin, Phys. Rev. Lett. 123, 080601 (2019)]. As in the classical case, the whole construction becomes intelligible by considering the dynamical symmetries of the problem.
