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…
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…
