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…
Krylov complexity in quantum many-body scars of spin-1 models
Qingmin Hu, Wen-Yi Zhang, Yunguang Han +1
Weak ergodicity breaking, particularly through quantum many-body scars (QMBS), has become a significant focus in many-body physics. Krylov state complexity quantifies the spread of…
Deconfined quantum criticality of frustrated hard-core dipolar bosons
Ya-Nan Wang, Wen-Long You, Wen-Yi Zhang +2
Deconfined quantum critical points (DQCPs) are proposed as unconventional second-order phase transitions beyond the Landau-Ginzburg-Wilson paradigm. The nature and experimental rea…
Quantum criticality of generalized Aubry-André models with exact mobility edges using fidelity susceptibility
Yu-Bin Liu, Wen-Yi Zhang, Tian-Cheng Yi +3
In this study, we explore the quantum critical phenomena in generalized Aubry-André models, with a particular focus on the scaling behavior at various filling states. Our approach…
Exploring quantum criticality and ergodicity-breaking dynamics in spin-1 Kitaev chains via single-ion anisotropies
Wen-Yi Zhang, Qing-Min Hu, Jie Ren +2
We investigate topological gauge-theory terms and quantum criticality in a spin-1 Kitaev chain with general single-ion anisotropies (SIAs). The ground-state phase diagram, includin…
