论文摘要
我们提出了一种基于Wigner函数的方法，用于费米和骨开放量子多体系统的粒子密度演化，包括dephasing的效果。特别是，我们专注于与lindblad浴的非相互作用颗粒的链。线性和二次跳转算子描述的耗散过程是由不均匀的耦合调节的。遵循半古典方法，我们发现控制Wigner函数演化的微分方程，在某些特定情况下可以以封闭形式解决。我们在不同情况下（即高斯跳跃速率）检查Wigner方法的准确性，描述了经典准粒子的密度演化和传输现象。
We present a Wigner function-based approach for the particle density evolution in fermionic and bosonic open quantum many-body systems, including the effects of dephasing. In particular, we focus on chains of non-interacting particles coupled to Lindblad baths. The dissipative processes, described by linear and quadratic jump operators, are modulated by inhomogeneous couplings. Following a semi-classical approach, we find the differential equation governing the Wigner function evolution, which can be solved in closed form in some particular cases. We check the accuracy of the Wigner approach in different scenarios (i.e. Gaussian jump rates), describing the density evolution and the transport phenomena in terms of classical quasi-particles.
