Topological Aspect of Knotted Vortex Filaments in Excitable Media
Ji-Rong Ren, Tao Zhu, Yi-Shi Duan
Scroll waves exist ubiquitously in three-dimensional excitable media. It's rotation center can be regarded as a topological object called vortex filament. In three-dimensional spac…
Topology of Knotted Optical Vortices
Ji-Rong Ren, Tao Zhu, Yi-Shi Duan
Optical vortices as topological objects exist ubiquitously in nature. In this paper, by making use of the -mapping topological current theory, we investigate the topology in the…
Magnetic Vortex Line Configuration of Faddeev-Niemi Knot
Yi-Shi Duan, Li-Da Zhang, Yu-Xiao Liu
This paper has been withdrawn by the author due to the inaccurate result.
Fermionic Zero Modes in Gauge and Gravity Backgrounds on a Sphere
Yu-Xiao Liu, Li-Jie Zhang, Yi-Shi Duan
In this letter we study fermionic zero modes in gauge and gravity backgrounds taking a two dimensional compact manifold as extra dimensions. The result is that there exist ma…
Localization of fermionic fields on braneworlds with bulk tachyon matter
Xin-Hui Zhang, Yu-Xiao Liu, Yi-Shi Duan
Recently, Pal and Skar in [arXiv:hep-th/0701266] proposed a mechanism to arise the warped braneworld models from bulk tachyon matter, which are endowed with a thin brane and a thic…
Fermions in gravity and gauge backgrounds on a brane world
Li Zhao, Yu-Xiao Liu, Yi-Shi Duan
We solve the fermionic zero modes in gravity and gauge backgrounds on a brane involving a warped geometry, and study the localization of spin 1/2 fermionic field on the brane world…
