Current Fluctuations in One-Dimensional Diffusion-Reaction Systems via Tensor Networks
Jiayin Gu
Tensor networks are employed to characterize the current fluctuations in one-dimensional diffusion-reaction systems. The representative system under study is a semiconducting mater…

Upper Bounded Current Fluctuations in One-Dimensional Driven Transport Systems
Jiayin Gu, Fan Zhang
We conjecture that the current fluctuations in one-dimensional driven transport systems obey an upper bound determined by the mean current and the driving force. This inequality or…

Generic Method for Integrating Lindblad Master Equations
Jiayin Gu, Fan Zhang
The time evolution of Markovian open quantum systems is governed by Lindblad master equations, whose solution can be formally written as the Lindbladian exponential acting on the i…
