Quantum criticality of the Lipkin-Meshkov-Glick Model in terms of fidelity susceptibility
Ho-Man Kwok, Wen-Qiang Ning, Shi-Jian Gu +1
We study the critical properties of the Lipkin-Meshkov-Glick Model in terms of the fidelity susceptibility. By using the Holstein-Primakoff transformation, we obtain explicitly the…
Fidelity susceptibility, scaling, and universality in quantum critical phenomena
Shi-Jian Gu, Ho-Man Kwok, Wen-Qiang Ning +1
We study fidelity susceptibility in one-dimensional asymmetric Hubbard model, and show that the fidelity susceptibility can be used to identify the universality class of the quantu…
One-dimensional spin pyrochlore lattice: exact ground state and elementary excitations
Shu Chen, Yupeng Wang, W. Q. Ning +2
We study the antiferromagnetic spin exchange models with and S=1 on a one-dimensional tetrahedron chain by both analytical and numerical approaches. The system is shown to…
Phonon Effects on Spin-Charge Separation in One Dimension
W. Q. Ning, Hui Zhao, C. Q. Wu +1
Phonon effects on spin-charge separation in one dimension are investigated through the calculation of one-electron spectral functions in terms of the recently developed cluster per…
