Universal scaling of finite-temperature quantum adiabaticity in driven many-body systems
Li-Ying Chou, Jyong-Hao Chen
Establishing quantitative adiabaticity criteria at finite temperature remains substantially less developed than in the pure-state setting, even though realistic quantum systems are…

Quantum adiabaticity in many-body systems and almost-orthogonality in complementary subspace
Jyong-Hao Chen, Vadim Cheianov
We investigate why, in quantum many-body systems, the adiabatic fidelity and the overlap between the initial state and instantaneous ground states often yield nearly identical valu…
