Perturbative Expansion around the Gaussian Effective Potential of the Fermion Field Theory
Geon Hyoung Lee, Tack Hwi Lee, Jae Hyung Yee
We have extended the perturbative expansion method around the Gaussian effective action to the fermionic field theory, by taking the 2-dimensional Gross-Neveu model as an example.…

Perturbative Expansion around the Gaussian Effective Action: The Background Field Method
Geon Hyoung Lee, Jae Hyung Yee
We develop a systematic method of the perturbative expansion around the Gaussian effective action based on the background field method. We show, by applying the method to the quant…

Gaussian approximation of the (2+1) dimensional Thirring model in the functional Schrödinger picture
S. J. Hyun, G. H. Lee, J. H. Yee
The (2+1)-dimensional Thirring model is studied by using the Gaussian approximation method in the functional Schrödinger picture. Although the dynamical symmetry breaking does not…
