Higher-order topological insulator in a modified Haldane-Hubbard model
Tian-Cheng Yi, Hai-Qing Lin, Rubem Mondaini
We investigate the ground-state phase diagram of a modified spinless Haldane-Hubbard model with broken threefold rotational symmetry, employing exact diagonalization calculations.…
Exploring unconventional quantum criticality in the p-wave-paired Aubry-André-Harper model
Ting Lv, Yu-Bin Liu, Tian-Cheng Yi +3
We have investigated scaling properties near the quantum critical point between the extended phase and the critical phase in the Aubry-André-Harper model with p-wave pairing, which…
Characterizing quantum criticality and steered coherence in the XY-Gamma chain
Zhuan Zhao, Tian-Cheng Yi, Ming Xue +1
In this paper, we show that an effective spin Hamiltonian with various types of couplings can be engineered using quantum simulators in atomic-molecular-optical laboratories, dubbe…
Recent neutron focusing experiments using polycapillary lens in CSNS
Kai Pan, Xue-Peng Sun, Tian-Cheng Yi +9
Higher neutron current densities can provide convenience for neutron experiments. Using neutron optical focusing elements, large flux beams transported to sample can be achieved. A…
Quantum criticality and universality in the -wave paired Aubry-André-Harper model
Ting Lv, Tian-Cheng Yi, Liangsheng Li +2
We investigate the quantum criticality and universality in Aubry-André-Harper (AAH) model with -wave superconducting pairing in terms of the generalized fidelity susceptibil…
