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…
Identifying the ground state phases by spin-patterns in the Shastry-Sutherland model
Yun-Tong Yang, Fu-Zhou Chen, Hong-Gang Luo
Exploring the influence of frustration on the phases and related phase transitions in condensed matter physics is of fundamental importance in uncovering the role played by frustra…
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…
Dissecting Superradiant Phase Transition in the Quantum Rabi Model
Yun-Tong Yang, Hong-Gang Luo
The phase transition is both thermodynamically and quantum-mechanically ubiquitous in nature or laboratory and its understanding is still one of most active issues in modern physic…
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…
The process of superradiant phase transition for quantum Rabi model in view of nonclassical states
Junpeng Liu, Miaomiao Zhao, Yun-Tong Yang +1
The ground state of quantum Rabi model (QRM) exhibits rich nonclassical states including squeezed state, cat state, and entangled state in different parameter regimes. In this pape…
Exotic Behavior of Parity in the Superradiant Phase of Quantum Rabi Model
Yun-Tong Yang, Junpeng Liu, Hong-Gang Luo
Parity describing the symmetry of quantum mechanics wavefunction under space inversion transformation not only plays an essential role in solving quantum systems but also can be us…
Characterizing Superradiant Phase of the Quantum Rabi Model
Yun-Tong Yang, Hong-Gang Luo
Recently, a superradiant phase transition first predicted theoretically in the quantum Rabi model (QRM) has been verified experimentally. This further stimulates the interest in th…
