Quantum many-body mixed phase space revealed by hybrid feedback control
Hang Dong, Jie Ren, Andrew Hallam +9
The paper introduces a hybrid quantum‑classical feedback protocol that discovers and stabilizes long‑lived regular trajectories in a superconducting quantum processor, revealing a…
Thermalization in a Height-Conserving Quantum Dimer Model
Junsheng Feng, Jie Ren, Zheng Yan
Strongly constrained quantum systems, in which local rules forbid most configurations, play a central role in condensed matter and lattice gauge theory. Their thermalization is oft…
ScarFinder: a detector of optimal scar trajectories in quantum many-body dynamics
Jie Ren, Andrew Hallam, Lei Ying +1
Mechanisms that give rise to coherent quantum dynamics, such as quantum many-body scars, have recently attracted much interest as a way of controlling quantum chaos. However, ident…
Superdiffusive transport protected by topology and symmetry in all dimensions
Shaofeng Huang, Yu-Peng Wang, Jie Ren +1
Superdiffusion is an anomalous transport behavior. Recently, a new mechanism, termed the ``nodal mechanism," has been proposed to induce superdiffusion in quantum models. However,…
Superdiffusive transport in chaotic quantum systems with nodal interactions
Yu-Peng Wang, Jie Ren, Sarang Gopalakrishnan +1
We introduce a class of interacting fermionic quantum models in dimensions with nodal interactions that exhibit superdiffusive transport. We establish non-perturbatively that t…
