Bose metal in exactly solvable model with infinite-range Hatsugai-Kohmoto interaction
Wei-Wei Yang, Hong-Gang Luo, Yin-Zhong
In a conventional boson system, the ground state can either be an insulator or a superfluid (SF) due to the duality between particle number and phase. This paper reveals that the l…
Robust superconducting correlation against inter-site interactions in the extended two-leg Hubbard ladder
Zongsheng Zhou, Weinan Ye, Hong-Gang Luo +2
The Hubbard and related models serve as a fundamental starting point in understanding the novel experimental phenomena in correlated electron materials, such as superconductivity,…
Friedel oscillation in non-Fermi liquid: Lesson from exactly solvable Hatsugai-Kohmoto model
Miaomiao Zhao, Wei-Wei Yang, Hong-Gang Luo +1
When non-magnetic impurity immerses in Fermi sea, a regular modulation of charge density around impurity will appear and such phenomena is called Friedel oscillation (FO). Although…
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…
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…
