Aharonov-Bohm effect in a Class of Noncommutative Theories
A. Das, H. Falomir, J. Gamboa +2
The Aharonov-Bohm effect including spin-noncommutative effects is considered. At linear order in , the magnetic field is gauge invariant although spatially strongly anisotropic.…
Supersymmetric Polytropic Gas Dynamics
Ashok Das, Ziemowit Popowicz
We construct the N=1 supersymmetric extension of the polytropic gas dynamics. We give both the Lagrangian as well as the Hamiltonian description of this system. We construct the in…
Properties of Moyal-Lax Representation
Ashok Das, Ziemowit Popowicz
The Moyal-Lax representation and the Moyal momentum algebra are introduced and systematically investigated. It is shown that the Moyal-Lax equation can be interpreted as a Hamilton…
THERMAL EFFECTS ON THE CATALYSIS BY A MAGNETIC FIELD
Ashok Das, Marcelo Hott
We show that the formation of condensates in the presence of a constant magnetic field in 2+1 dimensions is extremely unstable. It disappears as soon as a heat bath is introduced w…
DYNAMICAL SUPERSYMMETRY
Ashok Das, Marcelo Hott
We show, in a simple quantum mechanical model, how a theory can become supersymmetric in the presence of interactions even when the free theory is not. This dynamical generation of…
