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-…
