Anomalous spin transport in integrable random quantum circuits
Songlei Wang, Chenguang Liang, Hongzheng Zhao +1
High-temperature spin transport in integrable quantum spin chains exhibits a rich dynamical phase diagram, including ballistic, superdiffusive, and diffusive regimes. While integra…
Exact spin helix eigenstates in the anisotropic spin- Heisenberg model with arbitrary dimensions
Mingchen Zheng, Chenguang Liang, Shu Chen +1
Spin helix states-characterized by their spatially modulated spin textures-are exact eigenstates of the one-dimensional anisotropic spin- Heisenberg model under specif…
Types of dynamical behavior in a quasiperiodic mosaic lattice
Yu Zhang, Chenguang Liang, Shu Chen
Quasiperiodic mosaic systems with the quasiperiodic potential being added periodically with a fixed lattice interval have attracted significant attention due to their peculiar spec…
Statistical and dynamical aspects of quantum chaos in a kicked Bose-Hubbard dimer
Chenguang Liang, Yu Zhang, Shu Chen
Systems of interacting bosons in double-well potentials, modeled by two-site Bose-Hubbard models, are of significant theoretical and experimental interest and attracted intensive s…
