Topological Excitation in an Antiferromagnetic Bose-Einstein Condensate
Yi-shi Duan, Jun-ping Wang, Xin Liu +1
Two kinds of topological excitations, skyrmions and monopoles, are studied. It is revealed that these two types of excitations originate from different order parameter fields that…

Knotlike Cosmic Strings in The Early Universe
Yi-shi Duan, Xin Liu
In this paper, the knotlike cosmic strings in the Riemann-Cartan space-time of the early universe are discussed. It has been revealed that the cosmic strings can just originate fro…

Cosmic Strings and Quintessence
Yi-Shi Duan, Ji-Rong Ren, Jie Yang
We present a new Lorentz gauge invariant U(1) topological field theory in Riemann-Cartan spacetime manifold . By virtue of the decomposition theory of U(1) gauge potential a…
