Absence of measurement-induced entanglement transition due to feedback-induced skin effect
Yu-Peng Wang, Chen Fang, Jie Ren
A quantum many-body system subject to unitary evolution and repeated local measurements with an increasing rate undergoes a measurement-induced entanglement transition from extensi…
Deformed Symmetry Structures and Quantum Many-body Scar Subspaces
Jie Ren, Chenguang Liang, Chen Fang
A quantum many-body scar system usually contains a special non-thermal subspace (approximately) decoupled from the rest of the Hilbert space. In this work, we propose a general str…
A effective Hamiltonian generator
Yi Jiang, Zhong Fang, Chen Fang
effective Hamiltonian is important for theoretical analysis in condensed matter physics. Based on the 'kdotp-symmetry' package, we develop an upgraded package named 'kdo…
Quasi-symmetry groups and many-body scar dynamics
Jie Ren, Chenguang Liang, Chen Fang
In quantum systems, a subspace spanned by degenerate eigenvectors of the Hamiltonian may have higher symmetries than those of the Hamiltonian itself. When this enhanced-symmetry gr…
