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…
