Ground state properties of the one-dimensional axial next-nearest-neighbor Ising model in a transverse field
Yun-Tong Yang, Fu-Zhou Chen, Hong-Gang Luo
Describing and understanding the consequences of competing interactions remains profoundly challenging in both classical and quantum systems, as it is difficult to identify suitabl…

On the Origin of the Hidden Symmetry in the Asymmetric Quantum Rabi Model
Yun-Tong Yang, Song-Ming Chen, Hong-Gang Luo
The introduction of an asymmetric term into the quantum Rabi model generally lifts energy-level degeneracies. However, when the asymmetry parameter takes specific multiples of the…

Dissecting Quantum Phase Transition in the Transverse Ising Model
Yun-Tong Yang, Fu-Zhou Chen, Hong-Gang Luo
Despite the fact that a complete theoretical description of critical phenomena in connection with phase transitions has been well-established through the renormalization group theo…
