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…
Phase diagram of a Bose-Fermi mixture in a one-dimensional optical lattice in terms of fidelity and entanglement
Wen-Qiang Ning, Shi-Jian Gu, Chang-Qin Wu +1
We study the ground-state phase diagram of a Bose-Fermi mixture loaded in a one-dimensional optical lattice by computing the ground-state fidelity and quantum entanglement. We find…
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…
