Quantum many-body mixed phase space revealed by hybrid feedback control
Hang Dong, Jie Ren, Andrew Hallam +9
Understanding how complex systems transition between order and chaos is a central challenge of nonequilibrium physics. While weak perturbations of classical integrable systems give…
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…
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,…
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 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…
Quasi-Nambu-Goldstone modes in many-body scar models
Jie Ren, Yu-Peng Wang, Chen Fang
From the quasisymmetry-group perspective [Phys. Rev. Lett. 126, 120604 (2021)], we show the universal existence of collective, coherent modes of excitations in many-body scar model…
Superdiffusive transport on lattices with nodal impurities
Yu-Peng Wang, Jie Ren, Chen Fang
We show that 1D lattice models exhibit superdiffusive transport in the presence of random "nodal impurities" in the absence of interaction. Here a nodal impurity is defined as a lo…
Superdiffusive Transport in Quasi-Particle Dephasing Models
Yu-Peng Wang, Chen Fang, Jie Ren
Investigating the behavior of noninteracting fermions subjected to local dephasing, we reveal that quasi-particle dephasing can induce superdiffusive transport. This superdiffusion…
