Quasi-exact solvability of Dirac-Pauli equation and generalized Dirac oscillators
Choon-Lin Ho, Pinaki Roy
We demonstrate that neutral Dirac particles in external electric fields, which are equivalent to generalized Dirac oscillators, are physical examples of quasi-exactly solvable syst…
Space-Time Symmetries in Noncommutative Gauge Theory: A Hamiltonian Analysis
Subir Ghosh
We study space-time symmetries in Non-Commutative (NC) gauge theory in the (constrained) Hamiltonian framework. The specific example of NC CP(1) model, posited in \cite{sg}, has be…
Maxwell-Chern-Simons Theory is Free for Marginally Noncommutative Spacetimes
Subir Ghosh
We have conclusively established the duality between noncommutative Maxwell-Chern-Simons theory and Self-Dual model, the latter in ordinary spacetime, to the first non-trivial orde…
Effective Field Theory for Noncommutative Spacetime: A Toy Model
Subir Ghosh
A novel geometric model of a noncommutative plane has been constructed. We demonstrate that it can be construed as a toy model for describing and explaining the basic features of p…
The Seiberg-Witten Map in Noncommutative Field Theory: An Alternative Interpretation
Subir Ghosh
In this article, an alternative interpretation of the Seiberg-Witten map in non-commutative field theory is provided. We show that the Seiberg-Witten map can be induced in a geomet…
Soldering Formalism in Noncommutative Field Theory: A Brief Note
Subir Ghosh
In this paper, I develop the Soldering formalism in a new domain - the noncommutative planar field theories. The Soldering mechanism fuses two distinct theories showing opposite or…
