Effect of dynamical noncommutativity on the limiting mass of white dwarfs
Sayan K Pal, Partha Nandi
The discovery of the existence of an upper bound on the mass of a white dwarf star is considered as one of the finest of twentieth century astrophysics. On approaching this limitin…
Fuzzy Classical Dynamics as a Paradigm for Emerging Lorentz Geometries
F. G. Scholtz, P. Nandi, S. K. Pal +1
We show that the classical equations of motion for a particle on three dimensional fuzzy space and on the fuzzy sphere are underpinned by a natural Lorentz geometry. From this geom…
Particle Dynamics and Lie-algebraic type of Non-commutativity of space-time
Partha Nandi, Sayan Kumar Pal, Ravikant Verma
In this paper, we present the results of our investigation relating particle dynamics and non-commutativity of space-time by using Dirac's constraint analysis. In this study, we re…
Connecting dissipation and noncommutativity: A Bateman system case study
Sayan Kumar Pal, Partha Nandi, Biswajit Chakraborty
Quantum effects on a pair of Bateman oscillators embedded in an ambient noncommutative space (Moyal plane) is analyzed using both path integral and canonical quantization schemes w…
Quantum mechanics with space-time noncommutativity
Partha Nandi, Sayan Kumar Pal, Aritra N Bose +1
We construct an effective commutative Schrödinger equation in Moyal space-time in -dimension where both and are operator-valued and satisfy $\left[ \hat{t}, \hat{x}…
