Chiral Condensate in Two Dimensional Models
V. G. Ksenzov
We investigate two different models. In one of them massive fermions interact with a massive scalar field and in the other the fermion field is in an electrical field (QED2). The c…
Zero Points of Chiral Condensate
V. G. Ksenzov, A. I. Romanov
We investigate a model with a massless fermion and a massive scalar field with the Yukawa interaction between these two fields. The model possess a discrete symmetry. The chiral co…
Chiral condensate beyond one-loop approximation
V. G. Ksenzov, A. I. Romanov
We study two-dimensional model with a fermion field and a self-interaction scalar field with the Yukawa interaction beyond the framework of the one-loop approximation. We show that…
Phase Transitions in Models with Discrete Symmetry
V. G. Ksenzov, A. I. Romanov
We investigate a class of models with a massless fermion and a self-interacting scalar field with the Yukawa interaction between these two fields. The models considered are formula…
Dynamical Symmetry Breaking in Models with the Yukawa Interaction
V. G. Ksenzov, A. I. Romanov
We discuss models with a massless fermion and a self-interacting massive scalar field with the Yukawa interaction. The chiral condensate and the fermion mass are calculated analyti…
Stable branches of a solution for a fermion on domain wall
V. A. Gani, V. G. Ksenzov, A. E. Kudryavtsev
We discuss the case when a fermion occupies an excited non-zero frequency level in the field of domain wall. We demonstrate that a solution exists for the coupling constant in the…
Example of a self-consistent solution for a fermion on domain wall
V. A. Gani, V. G. Ksenzov, A. E. Kudryavtsev
We discuss a self-consistent solution for a fermion coupled to static scalar field in the form of a kink (domain wall). In particular, we study the case when the fermion occupies a…
On the Calculation of the Vacuum Energy Density in Sigma Models
V. G. Ksenzov
The vacuum energy density is calculated for the nonlinear sigma models in two dimensions. To obtain we assume that each point of the space in which non-p…
