Worldline algorithm by oracle-guided variational autoregressive network
Zhifang Shi, Yuchuang Cao, Qiangqiang Gu +1
The variational autoregressive network is extended to the Euclidean path integral representation of quantum partition function. An essential challenge is adapting the sequential pr…
Berezinskii-Kosterlitz-Thouless transition in two dimensional random-bond XY model on a square lattice
Yi-Bo Deng, Qiang Gu
We perform Monte Carlo simulations to study the two dimensional random-bond XY model on a square lattice. Two kinds of bond randomness with the coupling coefficient obeying the Gau…
Magnetic properties of two-dimensional charged spin-1 Bose gases
Yingxue Chen, Jihong Qin, Qiang Gu
Within the mean-field theory, we investigate the magnetic properties of a charged spin-1 Bose gas in two dimension. In this system the diamagnetism competes with paramagnetism, whe…
Magnetic properties of charged spin-1 Bose gases with ferromagnetic coupling
Jihong Qin, Xiaoling Jian, Qiang Gu
Magnetic properties of a charged spin-1 Bose gas with ferromagnetic interactions is investigated within mean-field theory. It is shown that a competition between paramagnetism, dia…
Competition between paramagnetism and diamagnetism in charged Fermi gases
Xiaoling Jian, Jihong Qin, Qiang Gu
The charged Fermi gas with a small Lande-factor is expected to be diamagnetic, while that with a larger could be paramagnetic. We calculate the critical value of the -fa…
Diamagnetism versus Paramagnetism in charged spin-1 Bose gases
Xiaoling Jian, Jihong Qin, Qiang Gu
It has been suggested that either diamagnetism or paramagnetism of Bose gases, due to the charge or spin degrees of freedom respectively, appears solely to be extraordinarily stron…
