Melting of quantum Hall Wigner and bubble crystals
H. Xia, Qianhui Xu, Jiasen Niu +7
A two-dimensional crystal melts via the proliferation and unbinding of topological defects, yet quantitatively predicting the melting temperature in real systems is challengi…
Hybrid Monte Carlo for Fractional Quantum Hall States
Ting-Tung Wang, Ha Quang Trung, Qianhui Xu +3
We develop a hybrid Monte Carlo method to efficiently compute the physical observables from the samplings of the Laughlin and the Moore-Read wave functions of fractional quantum Ha…
Dynamics of Anyon Clusters in Fractional Quantum Hall Fluids
Qianhui Xu, Guangyue Ji, Yuzhu Wang +2
In fractional quantum Hall fluids, the quasiparticle excitations are anyons with fractional charges and statistics. Effective interactions among the anyons can be induced by either…
Long-range Entanglement and Role of Realistic Interaction in Braiding of Non-Abelian Quasiholes in Fractional Quantum Hall Phases
Ha Quang Trung, Qianhui Xu, Bo Yang
Parity conservation dictates that when fusing pairs of Moore-Read (MR) quasiholes, such that each pair of charge- anyon forms a charge- anyon, the parity of the numbers o…
