Chern-Simons Gauge Invariance and Boundary Conformal Fields
Kumar Abhinav, Samir K. Paul
The topological non-Abelian Chern-Simons theory with a boundary is shown to require a scalar field companion in order to preserve overall gauge-invariance both in the 3 dimensional…
Semi-phenomenological analysis of neutron scattering results for quasi-two dimensional quantum anti-ferromagnet
Subhajit Sarkar, Ranjan Chaudhury, Samir K. Paul
The available results from the inelastic neutron scattering experiment performed on the quasi-two dimensional spin anti-ferromagnetic material have been…
The connection between vortex-like topological excitations and conventional excitations in quantum ferromagnetic spin systems on two dimensional lattice and their stability
Subhajit Sarkar, Ranjan Chaudhury, Samir K. Paul
We present a scheme for the construction of quantum states of vortex like topological excitations corresponding to spin- 1/2 strongly XY anisotropic nearest neighbor Heisenberg Fer…
Theoretical analysis of neutron scattering results for quasi-two dimensional ferromagnets
Subhajit Sarkar, Samir K. Paul, Ranjan Chaudhury
A theoretical study has been carried out to analyse the available results from the inelastic neutron scattering experiment performed on a quasi-two dimensional spin-1/2 ferromagnet…
Consistent 3D Quantum Gravity on Lens Spaces
Rudranil Basu, Samir K Paul
We study non-perturbative quantization of 3d gravity with positive cosmological constant (de Sitter space being the prototype vacuum solution, whose Euclideanization of course give…
Quillen bundle and Geometric Prequantization of Non-Abelian Vortices on a Riemann surface
Rukmini Dey, Samir K. Paul
In this paper we prequantize the moduli space of non-abelian vortices. We explicitly calculate the symplectic form arising from the metric and we construct a prequantum line…
