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-…
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 th…
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…
Exact zeros of fidelity in finite-size systems as a signature for probing quantum phase transitions
Yumeng Zeng, Bozhen Zhou, Shu Chen
The fidelity is widely used to detect quantum phase transitions, which is characterized by either a sharp change of fidelity or the divergence of fidelity susceptibility in the the…
Observation of size-dependent boundary effects in non-Hermitian electric circuits
Luhong Su, Cui-Xian Guo, Yongliang Wang +5
The non-Hermitian systems with the non-Hermitian skin effect (NHSE) are very sensitive to the imposed boundary conditions and lattice size, which leads to size-dependent non-Hermit…
