Computing Large Deviations of First-Passage-Time Statistics in Open Quantum Systems: Two Methods
Fei Liu, Jiayin Gu
We propose two methods for computing the large deviations of the first-passage-time statistics in general open quantum systems. The first method determines the region of convergenc…
Stochastic Thermodynamics of the Two-Dimensional Model of Transistors
Jiayin Gu
We adopt a stochastic approach to study the charge transport in transistors. In this approach, the hole and electron densities are ruled by diffusion-reaction stochastic partial di…
Stochastic Scovil--Schulz-DuBois machine and its three types of cycles
Fei Liu, Jiayin Gu
Three types of cycles are identified in the quantum jump trajectories of the Scovil--Schulz-DuBois (SSDB) machine: an R-cycle as refrigeration, an H-cycle as a heat engine, and an…
Responses for one-dimensional quantum spin systems via tensor networks
Jiayin Gu
Tensor networks are adopted to calculate the responses for one-dimensional quantum spin systems that are initially in thermal equilibrium. The Ising chain in mixed transverse and l…
