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…

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…
