Dimensional transmutation and symmetry breaking in Maxwell- Chern-Simons scalar QED [PDF]
, 1995 The mechanism of dimensional transmutation is discussed in the context of Maxwell-Chern-Simons scalar QED. The method used is non-perturbative. The effective potential describes a broken symmetry state.

A non-perturbative approach to the Coleman- Weinberg mechanism in massless scalar QED [PDF]
, 1995 We rederive non-perturbatively the Coleman-Weinberg expression for the effective potential for massless scalar QED. Our result is not restricted to small values of the coupling constants.

The 2(2S+1)- Formalism and Its Connection with Other Descriptions [PDF]
, 1993 In the framework of the Joos-Weinberg 2(2S+1)- theory for massless particles, the dynamical invariants have been derived from the Lagrangian density which is considered to be a 4- vector.

Pseudoclassical model for Weyl particle in 10 dimensions [PDF]
, 1995 A pseudoclassical model to describe Weyl particle in 10 dimensions is proposed. In course of quantization both the massless Dirac equation and the Weyl condition are reproduced automatically.

Groundstate with Zero Eigenvalue for Generalized Sombrero-shaped Potential in $N$-dimensional Space [PDF]
, 2007 Based on an iterative method for solving the goundstate of Schroedinger equation, it is found that a kind of generalized Sombrero-shaped potentials in N-dimensional space has groundstates with zero eigenvalue.

Chiral Bosons Through Linear Constraints [PDF]
, 1992 We study in detail the quantization of a model which apparently describes chiral bosons. The model is based on the idea that the chiral condition could be implemented through a linear constraint.

Symmetries and degrees of freedom in 2-dimensional dual models [PDF]
, 1998 The 2-dimensional version of the Schwarz and Sen duality model (Tseytlin model) is analyzed at the classical and quantum levels. The solutions are obtained after removing the gauge dependent sector using the Dirac method.

Classical Limit of Relativistic Quantum Mechanical Equations in the Foldy-Wouthuysen Representation [PDF]
, 2013 It is shown that, under the Wentzel-Kramers-Brillouin approximation conditions, using the Foldy-Wouthuysen representation allows the problem of finding a classical limit of relativistic quantum mechanical equations to be reduced to the replacement of ...
