New approach to Hamiltonian formulation of Hall magnetohydrodynamics
Kuldeep Kumar
We present a new Hamiltonian formulation of barotropic Hall magnetohydrodynamics in two complementary approaches based on Dirac's constraint analysis. In one case the Hamiltonian i…
Superunitary operator and BRST transformations for non-Abelian two-form
Dheeraj Shukla, Kuldeep Kumar
Using superspace unitary operator formalism, we derive various (anti-)BRST symmetry transformations explicitly for the non-Abelian 2-form gauge theories. We introduce a new Lagrang…
New approach to nonrelativistic ideal magnetohydrodynamics
Rabin Banerjee, Kuldeep Kumar
We provide a novel action principle for nonrelativistic ideal magnetohydrodynamics in the Eulerian scheme exploiting a Clebsch-type parametrisation. Both Lagrangian and Hamiltonian…
Reply to "Comment on 'Noncommutative gauge theories and Lorentz symmetry'"
Rabin Banerjee, Biswajit Chakraborty, Kuldeep Kumar
This is a reply to "Comment on 'Noncommutative gauge theories and Lorentz symmetry,'" Phys. Rev. D 77 (2008) 048701 by Alfredo Iorio.
Symmetries of Snyder--de Sitter space and relativistic particle dynamics
Rabin Banerjee, Kuldeep Kumar, Dibakar Roychowdhury
We study the deformed conformal-Poincare symmetries consistent with the Snyder--de Sitter space. A relativistic particle model invariant under these deformed symmetries is given. T…
Aspects of noncommutativity in field theory, strings and membranes
Kuldeep Kumar
We study certain aspects of noncommutativity in field theory, strings and membranes. We analyse the dynamics of an open membrane whose boundary is attached to p-branes. Noncommutat…
