Joule Thomson expansion of -deformed Schwarzschild-AdS black hole

Vishnu Rajagopal, Puxun Wu

We investigate the Joule-Thomson expansion of a non-commutative Schwarzschild-AdS black hole, whose space-time geometry is described by the Lie-algebraic -deformed space-time, a…

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…

Thermal Casimir effect in -Minkowski space-time

Suman Kumar Panja, Vishnu Rajagopal

We study the finite temperature Casimir effect for parallel plates in the -Minkowski space-time. Using the Matsubara formalism and imposing the Dirichlet boundary conditions on…

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…
