Generalized Uncertainty Principle Corrections to the Simple Harmonic Oscillator in Phase Space
Saurya Das, Matthew P. G. Robbins, Mark A. Walton
We compute Wigner functions for the harmonic oscillator including corrections from generalized uncertainty principles (GUPs), and study the corresponding marginal probability densi…
Discreteness of time in the evolution of the universe
Mir Faizal, Ahmed Farag Ali, Saurya Das
In this paper, we will first derive the Wheeler-DeWitt equation for the generalized geometry which occurs in M-theory. Then we will observe that M2-branes act as probes for this ge…
Dark matter and dark energy from Bose-Einstein condensate
Saurya Das, Rajat K. Bhaduri
We show that Dark Matter consisting of bosons of mass of about 1eV or less has critical temperature exceeding the temperature of the universe at all times, and hence would have for…
Cosmic coincidence or graviton mass?
Saurya Das
Using the quantum corrected Friedmann equation, obtained from the quantum Raychudhuri equation, and assuming a small mass of the graviton (but consistent with observations and theo…
Cosmology from quantum potential
Ahmed Farag Ali, Saurya Das
It was shown recently that replacing classical geodesics with quantal (Bohmian) trajectories gives rise to a quantum corrected Raychaudhuri equation (QRE). In this article we deriv…
