Detecting quantum phase transitions via shallow variational quantum circuits
Ching-Yu Huang, Min-Fong Yang
Mapping quantum phase diagrams through classical simulation is notoriously resource-intensive, as even small systems far from the thermodynamic limit demand prohibitive computation…

Subsystem Thermalization and Work Statistical Characterizations of Floquet Dynamics
Feng-Li Lin, Ching-Yu Huang
We study Floquet thermalization in a periodically driven quantum non-integrable Ising chain by combining two operational diagnostics: subsystem thermalization and work statistics.…

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 symmetry, XXZ chain with symmetry, and XXX chain with symmetries. Two kind…
