Electroweak Strings in the Standard Model
Liping Zou, Pengming Zhang, Yongmin Cho
We argue that the existence of the electroweak monopole predicts the existence of the electroweak string in the standard model made of monopole-antimonopole pair separated infinite…

Zero, Normal and Super-radiant Modes for Scalar and Spinor Fields in Kerr-anti de Sitter Spacetime
Masakatsu Kenmoku, Yongmin Cho, Kazuyasu Shigemoto +1
Zero and normal modes for scalar and spinor fields in Kerr-anti de Sitter spacetime are studied as bound state problem with Dirichlet and Neumann boundary conditions. Zero mode is…

Solution-generating methods of Einstein's equations by Hamiltonian reduction
Seung Hun Oh, Kyoungtae Kimm, Yongmin Cho +1
The purpose of this paper is to demonstrate a new method of generating exact solutions to the Einstein's equations obtained by the Hamiltonian reduction. The key element to the suc…
