Krylov complexity of anyons
Ya-Nan Wang, Qing-Min Hu, Wen-Long You +1
Anyons obey fractional statistics that lie between bosonic and fermionic statistics, giving rise to a broad range of intriguing phenomena. However, how anyonic statistics govern qu…
Generalized Aubry-André-Harper model with power-law quasiperiodic potentials
Ya-Nan Wang, Wen-Long You, Zhihao Xu +1
We investigate a generalized Aubry-André-Harper (AAH) model with non-reciprocal hopping and power-law quasiperiodic potentials . Our study r…
Non-Hermitian symmetry breaking and Lee-Yang theory for quantum XYZ and clock models
Tian-Yi Gu, Gaoyong Sun
Lee-Yang theory offers a unifying framework for understanding classical phase transitions and dynamical quantum phase transitions through the analysis of partition functions and Lo…
Fidelity zeros and Lee-Yang theory of quantum phase transitions
Tian-Yi Gu, Gaoyong Sun
Lee-Yang theory is central to the analysis of thermal phase transitions. However, the underlying mechanism of the theory and the nature of Lee-Yang zeros in quantum many-body syste…
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…
Quantum anomaly triggers the violation of scaling laws in gravitational system
Ya-Peng Hu, Yu-Sen An, Gao-Yong Sun +5
Scaling laws for critical phenomena take pivotal status in almost all branches of physics. However, as scaling laws are commonly guaranteed by the renormalization group theory, sys…
