Scaling behavior of dissipative systems with imaginary gap closing
Jinghui Pi, Xingli Li, Yangqian Yan
Point-gap topology, characterized by spectral winding numbers, is crucial to non-Hermitian topological phases and dramatically alters real-time dynamics. In this paper, we study th…

Signatures of Environment-Induced Quantum Synchronization Transitions via Two-body Dissipator Engineering
Xingli Li, Yan Li, Yangqian Yan
Metronome synchronization and the transition between the in-phase and anti-phase synchronization have been observed in classical systems. We demonstrate the quantum analog of this…

Canonical Quantum Mpemba Effect in a Dissipative Qubit
Xingli Li, Yan Li, Yangqian Yan
The Mpemba effect, where a hotter system cools faster than a colder one under otherwise identical conditions, has been extensively studied in classical systems. In this work, we pr…
