Pauli Spectrum and Stabilizer Rényi Entropy in Gapless Symmetry-Protected Topological Phases
Ying-Lin Li, Po-Yao Chang
Quantum entanglement is widely used as a diagnostic of topological phases of matter. Beyond entanglement, non-stabilizerness captures a distinct aspect of quantum many-body states…

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…

Chaotic-Integrable Transition for Disordered Orbital Hatsugai-Kohmoto Model
Ying-Lin Li, Chen-Te Ma, Po-Yao Chang
We have drawn connections between the Sachdev-Ye-Kitaev model and the multi-orbit Hatsugai-Kohmoto model, emphasizing their similarities and differences regarding chaotic behaviors…
