Metastable confinement in Rydberg lattice gauge theories
Yaohua Li, Devendra Singh Bhakuni, Yong-Chun Liu +1
Confinement and string breaking are two fundamental phenomena in gauge theories. Signatures of both are currently pursued in quantum-simulator experiments, opening a new angle on s…
General theory for geometry-dependent non-Hermitian bands
Chenyang Wang, Jinghui Pi, Qinxin Liu +2
In two- and higher-dimensional non-Hermitian lattices, systems can exhibit geometry-dependent bands, where the spectrum and eigenstates under open boundary conditions depend on the…
Open-system analogy of Berry conjecture
Yaohua Li, Yunhan Wang, Yong-Chun Liu
Berry conjecture is central to understanding quantum chaos in isolated systems and foundational for the eigenstate thermalization hypothesis. Here we establish an open-system analo…
Exact steady state of quantum van der Pol oscillator: critical phenomena and enhanced metrology
Yaohua Li, Xuanchen Zhang, Yong-Chun Liu
Quantum criticality of open many-body systems has attracted lots of interest for emergent phenomena and universality. Here we present the exact steady state of the quantum van der…
