Unveiling quantum criticality of disordered Aubry-André-Harper models via typical fidelity susceptibility
Tian-Cheng Yi, Ying-Ying Fang, Wen Chen +2
In this study, we investigate the localization transition and quantum criticality {in the ground state of the} disordered Aubry-André-Harper (AAH) model, where a quasiperiodic pot…

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…

Continuously varying critical exponents in an exactly solvable long-range cluster XY mode
Tian-Cheng Yi, Chengxiang Ding, Maoxin Liu +2
We investigate a generalized antiferromagnetic cluster XY model in a transverse magnetic field, where long-range interactions decay algebraically with distance. This model can be e…
