Modified Mukhanov-Sasaki equation and primordial perturbations in -deformed non-commutative space-time
Yang Lei, Vishnu Rajagopal, Puxun Wu
We study the inflationary primordial perturbations in -Minkowski non-commutative space-time, a Lie-algebraic type deformation of canonical space-time motivated by quantum gravi…
Thermodynamics and phase transitions of -deformed Schwarzschild-AdS black holes
A. Naveena Kumara, Vishnu Rajagopal, Puxun Wu
We investigate the thermodynamics of the Schwarzschild-AdS black hole in the framework of \(κ\)-deformed non-commutative geometry by constructing an effective \(κ\)-deformed Schw…
Search for possible signals of space-time non-commutativity from ACT DR6
Vishnu Rajagopal, Puxun Wu
The non-commutative geometry offers an effective framework for describing physics at the Planck scale, incorporating generic quantum-gravitational effects through an intrinsic mini…
Entropic force and bouncing behaviour in -Minkowski space-time
Vishnu Rajagopal, Puxun Wu
We generalise the entropic force description of gravity into -Minkowski space-time and derive the -deformed corrections to the Newton's gravitational force. Using this we s…
