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 gravit…
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 Schwar…
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 sho…
Unruh effect using Doppler shift method in DSR framework
Vishnu Rajagopal
We study the Unruh effect in doubly special relativity (DSR) framework by generalising the Doppler-shift method to DSR. For both the scalar and Dirac particles, we observe a deviat…
-deformed power spectrum and modified Unruh temperature
Vishnu Rajagopal
We study the power spectrum of the uniformly accelerating scalar field, obeying the -deformed Klein-Gordon equation. From this we obtain the -deformed corrections to the Unru…
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…
Emergence of maximal acceleration from non-commutativity of space-time
E. Harikumar, Leela Ganesh Chandra Lakkaraju, Vishnu Rajagopal
In this paper, we show that the causally connected -dimensional line element of the -deformed Minkowski space-time induces an upper cut-off on the proper acceleration and der…
Quantisation of -deformed Dirac equation
E. Harikumar, Vishnu Rajagopal
In this paper, we study the quantisation of Dirac field theory in the -deformed space-time. We adopt a quantisation method that uses only equations of motion for quantising the…
Maximal acceleration in non-commutative space-time and its implications
E. Harikumar, Vishnu Rajagopal
In this paper, we derive the non-commutative corrections to the maximal acceleration of a massive particle. Using the eight-dimensional kappa-deformed phase-space metric, we obtain…
Time-space noncommutativity and Casimir effect
E. Harikumar, Suman Kumar Panja, Vishnu Rajagopal
We show that the Casimir force and energy are modified in the kappa-deformed space-time. This is analysed by solving the Green's function corresponding to kappa-deformed scalar fie…
