Tighter thermalization bounds for perturbed quantum many-body scars
Meng-Yun Mao, Zhixiang Sun, Wen-Long You
Quantum many-body scars (QMBS) are exceptional eigenstates that defy thermalization, enabling long-lived coherent dynamics in strongly interacting systems. However, their stability…

Yang-Lee edge singularity and quantum criticality in non-Hermitian PXP model
Wen-Yi Zhang, Meng-Yun Mao, Qing-Min Hu +3
We present a comprehensive theoretical framework for quantum criticality in the non-Hermitian detuned PXP model, and establish the complete phase diagram, which had remained elusiv…
