Modelling a Noncommutative Two-Brane
Subir Ghosh
This paper has been superseded by hep-th/0307227.
Gauge Invariance and Duality in the Noncommutative Plane
Subir Ghosh
We show that the duality between the self-dual and Maxwell-Chern-Simons theories in 2+1-dimensions survives when the space-time becomes noncommutative. Existence of the Seiberg-Wit…
Quasi-exact Solvability of the Pauli Equation
Choon-Lin Ho, Pinaki Roy
We present a general procedure for determining possible (nonuniform) magnetic fields such that the Pauli equation becomes quasi-exactly solvable (QES) with an underlying sy…
Covariantly Quantized Spinning Particle and its Possible Connection to Non-Commutative Space-Time
Subir Ghosh
Covariant quantization of the Nambu-Goto spinning particle in 2+1-dimensions is studied. The model is relevant in the context of recent activities in non-commutative space-time. Fr…
Noncommutativity in open string: New results in a gauge independent analysis
Rabin Banerjee, Biswajit Chakraborty, Subir Ghosh
Noncommutativity in an open string moving in a background Neveu-Schwarz field is investigated in a gauge independent Hamiltonian approach, leading to new results. The noncommutativ…
A New Interpretation of the Seiberg Witten Map
Subir Ghosh
In an alternative interpretation, the Seiberg-Witten map is shown to be induced by a field dependent co-ordinate transformation connecting noncommutative and ordinary space-times.…
