Topological defects in two-dimensional crystals
Yong Chen, Wei-Kai Qi
By using topological current theory, we study the inner topological structure of the topological defects in two-dimensional (2D) crystal. We find that there are two elementary poin…

Topological dynamics and dynamical scaling behavior of vortices in a two-dimensional XY model
Wei-Kai Qi, Yong Chen
By using topological current theory we study the inner topological structure of vortices a two-dimensional (2D) XY model and find the topological current relating to the order para…

Coexistence of hexatic and isotropic phases in two-dimensional Yukawa systems
Wei-Kai Qi, Shao-Meng Qin, Xiao-Ying Zhao +1
We have performed Brownian dynamics simulations on melting of two-dimensional colloidal crystal in which particles interact with Yukawa potential. The pair correlation function and…
