Subsystem Thermalization Hypothesis in Quantum Spin Chains with Conserved Charges

Feng-Li Lin, Jhh-Jing Hong, Ching-Yu Huang

We consider the thermalization hypothesis of pure states in quantum Ising chain with $Z_2$ symmetry, XXZ chain with $U(1)$ symmetry, and XXX chain with $SU(2)$ symmetries. Two kind…
