Floquet-Sambe Bottleneck and Frequency-Selective Localization in a Driven Synthetic Spin Chain
J. Cao, K. L. Zhang, R. Wang +1
We study a finite Floquet chain in which a uniform nearest-neighbor hopping coexists with a periodically rotating, \textrm{SU(2)}-dictated spin-assisted hopping profile. The result…
Wave-packet revival in a Floquet engineering quadratic potential system
J. Cao, H. Shen, R. Wang +1
We investigate the quantum dynamics of a one-dimensional tight-binding lattice driven by a spatially quadratic and time-periodic potential. Both Hermitian () and non-Her…
Integrability Breaking and Coherent Dynamics in Hermitian and Non-Hermitian Spin Chains with Long-Range Coupling
Y. S. Liu, X. Z. Zhang
Unraveling the mechanisms of ergodicity breaking in complex quantum systems is a central pursuit in nonequilibrium physics. In this work, we investigate a one-dimensional spin mode…
Probing quantum phase transition in a staggered Bosonic Kitaev chain via layer-resolved localization-delocalization transition
R. Wang, X. Z. Zhang
The bosonic statistics, which allow for macroscopic multi-occupancy of single-particle states, pose significant challenges for analyzing quantum phase transitions in interacting bo…
