How does Casimir energy fall in -deformed space-time?
E. Harikumar, K. V. Shajesh, Suman Kumar Panja
We investigate the response of Casimir energies to fluctuations in a scalar field in a weak gravitational field in the -deformed space-time. We model the Casimir plates in a gra…
Neutron Star in Quantized-space-time
Bhagya. R, Diganta Parai, E. Harikumar +1
We construct and analyze a model of the neutron star in the k deformed space-time. This is done by first deriving the k deformed generalization of the Einstein tensor, starting fro…
Newtonian cosmology and Evolution of kappa-deformed universe
E. Harikumar, Harsha Sreekumar, Suman Kumar Panja
Considering space--time to be non-commutative, we study the evolution of the universe employing the approach of Newtonian cosmology. Generalizing the conservation of energy and the…
Maximal acceleration in a Lorentz invariant non-commutative space-time
E. Harikumar, Suman Kumar Panja, Vishnu Rajagopal
In this paper, we derive the non-commutative corrections to the maximal acceleration in the Doplicher-Fredenhagen-Roberts (DFR) space-time and show that the effect of the non-commu…
Quantisation of Lorentz invariant scalar field theory in non-commutative space-time and its consequence
E. Harikumar, Vishnu Rajagopal
Quantisation of Lorentz invariant scalar field theory in Doplicher-Fredenhagen-Roberts (DFR) space-time, a Lorentz invariant, non-commutative space-time is studied. Absence of a un…
Casimir effect in DFR space-time
E. Harikumar, Suman Kumar Panja
Non-Commutative space-time introduces a fundamental length scale suggested by approaches to quantum gravity. Here we report the analysis of the Casimir effect for parallel plates s…
