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…
Decoding Equilibrium and Dynamical Criticality in the 2D Topological Order
Xiao-Ming Zhao, Cui-Xian Guo, Gaoyong Sun +1
Analytically connecting equilibrium criticality and dynamical quantum phase transitions (DQPTs) under complex driving fields remains a significant challenge, primarily due to the c…
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…

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 reve…
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…
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…
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…
Dynamical signatures of the Yang-Lee edge singularity in non-Hermitian systems
Ming-Chu Lu, Shun-Hui Shi, Gaoyong Sun
The Yang-Lee edge singularity is an intriguing critical phenomenon characterized by nonunitary field theory. However, its experimental realization for interacting many-body systems…
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…

We study the critical behaviors of the ground and first excited states in the one-dimensional nonreciprocal Aubry-Andr{é}-Harper model using both the self-normal and biorthogonal f…
Many-body phase transitions in a non-Hermitian Ising chain
Chao-Ze Lu, Xiaolong Deng, Su-Peng Kou +1
We study many-body phase transitions in a one-dimensional ferromagnetic transversed field Ising model with an imaginary field and show that the system exhibits three phase transiti…
Many-body entanglement and spectral clusters in the extended hard-core bosonic Hatano-Nelson model
Chao-Ze Lu, Gaoyong Sun
We study many-body entanglements and spectra of the extended bosonic Hatano-Nelson model in the hard-core limit. We show that the system undergoes a phase transition from a gapless…
