A Novel "Magnetic" Field And Its Dual Non-Commutative Phase Space
Subir Ghosh
In this paper we have studied a new form of Non-Commutative (NC) phase space with an operatorial form of noncommutativity. A point particle in this space feels the effect of an int…
Lie Particle And Its Batalin-Tyutin Extension
Subir Ghosh, Probir Pal
In this Letter we have proposed a point particle model that generates a noncommutative three-space, with the coordinate brackets being Lie algebraic in nature, in particular isomor…
The particle
Subir Ghosh
In this note we have considered a relativistic Nambu-Goto model for a particle in metric. With appropriate gauge choice to fix the reparameterization invariance, we recover t…
-Minkowski Spacetime Through Exotic "Oscillator"
Subir Ghosh, Probir Pal
We have proposed a generally covariant non-relativistic particle model that can represent the -Minkowski noncommutative spacetime. The idea is similar in spirit to the noncommut…
