Quantumness and quantum to classical transition in the generalized Rabi model
Wei-Feng Zhuang, Yun-Tong Yang, Hong-Gang Luo +2
The quantum to classical transition (QCT) is one of the central mysteries in quantum physics. This process is generally interpreted as state collapse from measurement or decoherenc…
An explicit evolution from Néel to striped antiferromagnetic states in the spin-1/2 - Heisenberg model on the square lattice
Yun-Tong Yang, Fu-Zhou Chen, Chen Cheng +1
The frustrated spin- Heisenberg model on the square lattice has been extensively studied since 1988 because of its close relationship to the high-temperature superco…
Topological or not? A unified pattern description in the one-dimensional anisotropic quantum XY model with a transverse field
Yun-Tong Yang, Hong-Gang Luo
The nature of phase transitions involving the questions why and how phase transitions take place has not been sufficiently touched in the literature. In contrast, the current atten…
Pattern Description of Quantum Phase Transitions in the Transverse Antiferromagnetic Ising Model with a Longitudinal Field
Yun-Tong Yang, Hong-Gang Luo
Despite of simplicity of the transverse antiferromagnetic Ising model with a uniform longitudinal field, its phases and involved quntum phase transitions (QPTs) are nontrivial in c…
First-Order Excited-State Quantum Phase Transition in the Transverse Ising Model with a Longitudinal Field
Yun-Tong Yang, Hong-Gang Luo
The investigation of the first-order quantum phase transition (QPT) is far from clarity in comparison to that of the second-order or continuous QPT, in which the order parameter an…
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…
