New variational perturbation theory based on deformed oscillator
Hyeong-Chan Kim, Jae Hyung Yee, Sang Pyo Kim
A new variational perturbation theory is developed based on the deformed oscillator. It is shown that the new variational perturbation method provides 200 or 10 times better ac…
Scattering theory of space-time non-commutative abelian gauge field theory
Chaiho Rim, Jae Hyung Yee
The unitary S-matrix for the space-time non-commutative QED is constructed using the -time ordering which is needed in the presence of derivative interactions. Based on this…
Propagation of Light in Doubly Special Relativity
Sung Ku Kim, Sun Myong Kim, Chaiho Rim +1
In an attempt to clarify what is the velocity of a particle in doubly special relativity, we solve Maxwell's equations invariant under the position-space nonlinear Lorentz transfor…
Open and Closed Universes in Brane-World Cosmology
Hyeong-Chan Kim, Jae Hyung Yee, Mu-In Park
We find two types [called (S) and (A)] of new vacuum solutions of open, flat, and closed universes which are inflating in the brane-world scenario. We show that the warp factor of…
Vortex Solutions of a Fermion Maxwell-Chern-Simons Theory
Jae Hyung Yee
We explain how static multi-vortex solutions arise in non-linear field theories, by taking the non-linear Schrödinger equation coupled to Chern-Simons field (Jackiw-Pi model) and a…
Fractal Diffraction Grating
Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2
We consider an optical diffraction grating in which the spatial distribution of open slits forms a fractal set. The Fraunhofer diffraction patterns through the fractal grating are…
