Binding Energy of Scalar Bound State by Topologically Massive Interaction: Fermion and Anti-fermion System with Heavy Mass
Toyoki Matsuyama, Hideko Nagahiro
A bound state problem in a topologically massive quantum electrodynamics is investigated by using a non-perturbative method. We formulate the Bethe- Salpeter equation for scalar bo…
Topological Mass vs. Dynamical Mass: Novelty in (2+1)-dimensional Space-Time
Toyoki Matsuyama, Hideko Nagahiro
The restriction of space-time dimensions to "2+1" leads us to a novel quantum field theory which has the Chern-Simons term in its action. This term changes the nature of gauge inte…
Dynamical Mass and Parity Condensate in Varying Topological Mass
Toyoki Matsuyama, Hideko Nagahiro
We investigate how a dynamical mass of a fermion is affected by a topological mass of a gauge field in a Maxwell-Chern-Simons coupled with a two-component fermion. The dyna…
Dynamical mass generation of a two-component fermion in Maxwell-Chern-Simons QED_3: The lowest ladder approximation
Toyoki Matsuyama, Hideko Nagahiro, Satoko Uchida
Dynamical mass generation of a two-component fermion in with a Chern-Simons term is investigated by solving the Schwinger-Dyson equation formulated in the lowest ladder app…
Generalized Hamiltonian Formalism of (2+1)-Dimensional Non-Linear -Model in Polynomial Formulation
Toyoki Matsuyama
We investigate the canonical structure of the (2+1)-dimensional non-linear model in a formulation. A current density defined in the non-linear model is a vecto…
Canonical Structure of the Non-Linear Sigma-Model in a Polynomial Formulation
C. D. Fosco, T. Matsuyama
We study the canonical structure of the non-linear Sigma-model in a polynomial, first-order representation. The fundamental variables in this description are a non-Abelian…
The Polynomial Formulation of the U(1) Non-Linear Sigma-Model in 2 Dimensions
C. D. Fosco, T. Matsuyama
We investigate some properties of a first-order polynomial formulation of the U(1) non-linear sigma-model in two Euclidean dimensions. The variables in this description are a 1-for…
The Ladder Approximation in QED_2
C. D. Fosco, T. Matsuyama
We study the Schwinger-Dyson equation for the fermion self-energy in massless and massive , in the ladder approximation. When the fermion is massless (and the photon massles…
