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…
