Lattice Fermions and Chiral Symmetry
H. Banerjee, Asit K. De
We propose a formulation of lattice fermions with one-sided differences that is hermitian, chirally symmetric (barring a bare mass term) and completely free of doubling. To obtain…
Non abelian bosonisation in three dimensional field theory
N. Banerjee, R. Banerjee, S. Ghosh
We develop a method based on the generalised Stückelberg prescription for discussing bosonisation in the low energy regime of the SU(2) massive Thirring model in 2+1 dimensions. Fo…
A Class of Quantum Integrable Models Associated with the Infra-red Limit of Massive Chern-Simons Theory
V. V. Sreedhar
We study the infra-red limit of non-abelian Chern-Simons gauge theory perturbed by a non-topological, albeit gauge invariant, mass term. It is shown that, in this limit, we may con…
Van der Waerden's Colouring Theorem and Classical Spin Systems
R. Chaudhury, D. Gangopadhyay, S. K. Paul
We find a non-invertible matrix representation for Van der Waerden's colouring theorem for two distinct colours in a one dimensional periodic lattice. Using this,an infinite one di…
Spin of Chern-Simons vortices
R. Banerjee, P. Mukherjee
We discuss a novel method of obtaining the fractional spin of abelian and nonabelian Chern-Simons vortices. This spin is interpreted as the difference between the angular momentum…
On the Vortex-Point Charge Composite: Classical Orbits and Quantum Bound States
Subir Ghosh
The possibility of composite systems arising out of a point charge interacting with a Nielsen-Olesen vortex in 2+1-dimensions is investigated. It is shown that classical bounded or…
