Graphical Representations and Worm Algorithms for the O() Spin Model
Longxiang Liu, Lei Zhang, Xiaojun Tan +1
We present a family of graphical representations for the O() spin model, where represents the spin dimension, and corresponds to the Ising, XY and Heisenberg…
Worm-algorithm-type Simulation of Quantum Transverse-Field Ising Model
Chun-Jiong Huang, Longxiang Liu, Yi Jiang +1
We apply a worm algorithm to simulate the quantum transverse-field Ising model in a path-integral representation of which the expansion basis is taken as the spin component along t…
Evidences for interaction-induced Haldane fractional exclusion statistics in one and higher dimensions
Xibo Zhang, Yang-Yang Chen, Longxiang Liu +2
Haldane fractional exclusion statistics (FES) has a long history of intense studies, but its realization in physical systems is rare. Here we study repulsively interacting Bose gas…
Phases of superclimbing dislocation with long-range interaction between jogs
Longxiang Liu, Anatoly Kuklov
The main candidate for the superfluid pathways in solid Helium-4 are dislocations with Burgers vector along the hcp symmetry axis. Here we focus on quantum behavior of a generic ed…
Eta-mesic nuclei: past, present, future
Q. Haider, L. C. Liu
Eta-mesic nucleus or the quasibound nuclear state of an eta () meson in a nucleus is caused by strong-interaction force alone. This new type of nuclear species, which extends th…
The Massive Goldstone (Higgs) mode in two-dimensional ultracold atomic lattice systems
Longxiang Liu, Kun Chen, Youjin Deng +3
We discuss how to reveal the massive Goldstone mode, often referred to as the Higgs amplitude mode, near the Superfluid-to-Insulator quantum critical point (QCP) in a system of two…
