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…
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…
Probing the hollowing transition of a shell-shaped BEC with collective excitation
Zerong Huang, Kai Yuen Lee, Chun Kit Wong +4
We investigate the hollowing transition of a shell-shaped Bose-Einstein condensate using collective excitations. The shell is created using an immiscible dual-species BEC mixture,…
