Krylov complexity of a tilted extended Bose-Hubbard chain with Rydberg-dressed interactions

Yifan Chen, Tianyi Yan, Lu Qin +1

We investigate Krylov state complexity in a tilted extended Bose-Hubbard chain in which both the on-site interaction and nearest-neighbor interaction are present. The tilte…

Nonthermal Dynamics of a One-dimensional Rydberg-atom Chain with Constraint Four-body Interactions

Tianyi Yan, Weibin Li

We investigate dynamics of a linear chain of Rydberg atoms driven by a constrained four-body interaction, where two neighboring atoms are excited simultaneously from the electronic…

Entanglement-enabled Criticality in One-dimensional Quantum Contact Process

Ya-Xin Xiang, Tianyi Yan, Weibin Li +1

The contact process is a paradigmatic example of nonequilibrium dynamics, with broad applications ranging from chemistry to sociology. Its quantum counterpart, the quantum contact…

Engineer coherent oscillatory modes in Markovian open quantum systems

Chun Hei Leung, Pak-Tik Fong, Tianyi Yan +1

We develop a novel framework to engineer persistent oscillatory modes in Markovian open quantum systems governed by a time-independent Lindblad master equation. We show that oscill…

Hilbert space fragmentation in driven-dephasing Rydberg atom array

Tianyi Yan, Chun Hei Leung, Weibin Li

We investigate the onset and mechanism of Hilbert space fragmentation (HSF) in a chain of strongly interacting Rydberg atoms subject to local dephasing. It is found that the emerge…
