Few is different: deciphering many-body dynamics in mesoscopic quantum gases
Juergen Berges, Sandra Brandstetter, Jasmine Brewer +27
Emergent macroscopic descriptions of matter, such as hydrodynamics, are central to our description of complex physical systems across a wide spectrum of energy scales. The conventi…
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…
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,…
Interaction induced splitting of Dirac monopoles in the topological Thouless pumping of strongly interacting Bosons and SU() Fermions
Hei Lam, Yangqian Yan
Motivated by the observation of the breakdown of quantization for the Thouless pump in the presence of strong interaction by ETH [Walter et. al. Nat. Phys. 19, 1471 (2023), Viebahn…
