Dynamics of phase transition in (3+1) dimensional scalar theory
Hyeong-Chan Kim, Jae Hyung Yee
We use the variational approximation with double Gaussian type trial wave-functional approximation, in which we use the square root of the dispersion of the zero-mode wave-function…
Perturbation theory of the space-time non-commutative real scalar field theories
Chaiho Rim, Yunseok Seo, Jae Hyung Yee
The perturbative framework of the space-time non-commutative real scalar field theory is formulated, based on the unitary S-matrix. Unitarity of the S-matrix is explicitly checked…
Post Gaussian effective potential in the Ginzburg Landau theory of superconductivity
Chul Koo Kim, A. Rakhimov, Jae Hyung Yee
The post Gaussian effective potential in D=3 dimensions and the Gaussian effective potential in D=2+epsilon are evaluated for the Ginzburg-Landau theory of superconductivity. It is…
Zero mode in the time-dependent symmetry breaking of theory
Hyeong-Chan Kim, Jae Hyung Yee
We apply the quartic exponential variational approximation to the symmetry breaking phenomena of scalar field in three and four dimensions. We calculate effective potential and eff…
