Dirac Quantization Condition for Monopole in Noncommutative Space-Time
Masud Chaichian, Subir Ghosh, Miklos Langvik +1
Since the structure of space-time at very short distances is believed to get modified possibly due to noncommutativity effects and as the Dirac Quantization Condition (DQC), $μe =…
Non-Hermitian quantum mechanics in non-commutative space
Pulak Ranjan Giri, P Roy
We study non Hermitian quantum systems in noncommutative space as well as a \cal{PT}-symmetric deformation of this space. Specifically, a \mathcal{PT}-symmetric harmonic oscillator…
Noncommutative oscillator, symmetry and Landau problem
Pulak Ranjan Giri, P. Roy
Isotropic oscillator on a plane is discussed where both the coordinate and momentum space are considered to be noncommutative. We also discuss the symmetry properties of the oscill…
Three dimensional noncommutative bosonization
Rabin Banerjee, Subir Ghosh, T. Shreecharan
We consider the extension of the 2+1-dimensional bosonization process in Non-Commutative (NC) spacetime. We show that the large mass limit of the effective action obtained by integ…
Berry Phase Effects in the dynamics of Dirac Electrons in Doubly Special Relativity Framework
Pierre Gosselin, Alain Berard, Herve Mohrbach +1
We consider the Doubly Special Relativity (DSR) generalization of Dirac equation in an external potential in the Magueijo-Smolin base. The particles obey a modified energy-momentum…
Crypto-Harmonic Oscillator in Higher Dimensions: Classical and Quantum Aspects
Subir Ghosh, Bibhas Ranjan Majhi
We study complexified Harmonic Oscillator models in two and three dimensions. Our work is a generalization of the work of Smilga \cite{sm} who initiated the study of these Crypto-g…
