Exact solutions of hidden free fermion models
Mingchen Zheng, Balázs Pozsgay, Shu Chen
Hidden-free-fermion (HFF) Hamiltonians exhibit free-fermion spectra despite lacking an explicit quadratic representation, yet their algebraic provenance and periodic-boundary behav…
Bethe-root configurations and spectral degeneracy in the open XXZ chain with degenerate boundaries
Shizhang Wu, Shu Chen, Junpeng Cao +1
We investigate the structure of Bethe-root configurations in the spin-1/2 XXZ chain with degenerate open boundaries. The physical solutions of the Bethe Ansatz equations are classi…
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…
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-…
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…
Scale-tailored localization and its observation in non-Hermitian electrical circuits
Cui-Xian Guo, Luhong Su, Yongliang Wang +7
Anderson localization and non-Hermitian skin effect are two paradigmatic wave localization phenomena, resulting from wave interference and the intrinsic non-Hermitian point gap, re…
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…
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…
Spread complexity and dynamical transition in multimode Bose-Einstein condensates
Bozhen Zhou, Shu Chen
We study the spread complexity in two-mode Bose-Einstein condensations and unveil that the long-time average of the spread complexity can probe the dynamical tra…
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…
