Anomalous transport in long-ranged open quantum systems
We consider a one-dimensional fermionic lattice system with long-ranged power-law
decaying hopping with exponent α. The system is further subjected to dephasing noise in …

Kibble–Zurek scaling due to environment temperature quench in the transverse field Ising model
Á Bácsi, B Dóra - Scientific Reports, 2023 - nature.com
Abstract The Kibble–Zurek mechanism describes defect production due to non-adiabatic
passage through a critical point. Here we study its variant from ramping the environment …

Speeding up quantum heat engines by the Mpemba effect
D Liu, J Yuan, H Ruan, Y Xu, S Luo, J He, X He, Y Ma… - Physical Review A, 2024 - APS
The Mpemba effect is a counterintuitive relaxation phenomenon that a system which begins
hot can cool down faster than the identical system which is initially cold. Here, we investigate …

Local and global thermalization in non-Markovian open quantum system
LP Han, J Zou, H Li, B Shao - The European Physical Journal D, 2023 - Springer
In this paper, we study thermalization of spin chains whose two end spins interact with two
independent non-Markovian dephasing baths by the quantum state diffusion (QSD) …

Anti-thermalization: Heating by cooling and vice versa
Common intuition tells us that if one part of a connected system is cooled continuously, the
other parts should also cool down. This intuition can be given a microscopic foundation for …
