Hysteresis of bond-orientational order in 2D overdamped Yukawa systems
Weikai Qi, Yong Chen, Yilong Han
This paper has been withdrawn by the author due to need for more improvement.
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…
Topological aspect of disclinations in two-dimensional melting
Wei-Kai Qi, Tao Zhu, Yong Chen +1
By using topological current theory, we study the inner topological structure of disclinations during the melting of two-dimensional systems. From two-dimensional elasticity theory…
Many-body interactions and melting of colloidal crystals
J. Dobnikar, Y. Chen, R. Rzehak +1
We study the melting behavior of charged colloidal crystals, using a simulation technique that combines a continuous mean-field Poisson-Boltzmann description for the microscopic el…
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…
