Magic Entropy in Hybrid Spin-Boson Systems
Samuel Crew, Ying-Lin Li, Heng-Hsi Li +1
We introduce entropic measures to quantify non-classical resource in hybrid spin-boson systems. We discuss the stabilizer Rényi entropy in the framework of phase space quantisatio…

Impurity-induced non-unitary criticality
Heng-Hsi Li, Kuang-Hung Chou, Xueda Wen +1
Quantum impurities give rise to rich physical phenomena, with some exhibiting critical behavior described by conformal field theories (CFTs) in the low-energy limit. In parallel, p…

Phase transitions from Heating to non-heating in SU(1, 1) quantum dynamics: applications to Bose-Einstein condensates and periodically driven coupled oscillators
Heng-Hsi Li, Po-Yao Chang
We study the entanglement properties in non-equilibrium quantum systems with the SU(1, 1) structure. Through Möbius transformation, we map the dynamics of these systems following…
