Percolation of the two-dimensional XY model in the flow representation
Bao-Zong Wang, Pengcheng Hou, Chun-Jiong Huang +1
We simulate the two-dimensional XY model in the flow representation by a worm-type algorithm, up to linear system size , and study the geometric properties of the flow conf…
Fermionic Sign Structure of High-order Feynman diagrams in a Many-fermion System
Bao-Zong Wang, Peng-Cheng Hou, Youjin Deng +2
The sign cancellation between scattering amplitudes makes fermions different from bosons. We systematically investigate Feynman diagrams' fermionic sign structure in a representati…
Critical exponents and universal excess cluster number of percolation in four and five dimensions
Zhongjin Zhang, Pengcheng Hou, Sheng Fang +2
We study critical bond percolation on periodic four-dimensional (4D) and five-dimensional (5D) hypercubes by Monte Carlo simulations. By classifying the occupied bonds into branche…
