Entanglement transition and suppression of critical phase of thermofield double state in monitored quantum circuit with unitary matrix gates
Shi-Kang Sun, Shu Chen
We study quantum circuits with gates composed randomly of identity operators, projectors, or a kind of matrices which satisfy the Yang-Baxter equation and are unitary and dual-…
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…
Fate of Two-Particle Bound States in the Continuum in non-Hermitian Systems
Yanxia Liu, Shu Chen
We unveil the existence of two-particle bound state in the continuum (BIC) in a one-dimensional interacting nonreciprocal lattice with a generalized boundary condition. By applying…
Emergence of the Gibbs ensemble as a steady state in Lindbladian dynamics
Shi-Kang Sun, Shu Chen
We explicitly construct unique non-equilibrium steady state (NESS) of Lindblad master equation characterized by a Gibbs ensemble , where…
Lindbladian dynamics with loss of quantum jumps
Yu-Guo Liu, Shu Chen
The Lindblad master equation (LME) describing the Markovian dynamics of the quantum open system can be understood as the evolution of the effective non-Hermitian Hamiltonian balanc…
Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
Ze-Yu Xing, Shu Chen, Haiping Hu
Non-Hermitian systems exhibit a distinctive type of wave propagation, due to the intricate interplay of non-Hermiticity and disorder. Here, we investigate the spreading dynamics in…
