Time-like geodesic structure for the K-essence Emergent Barriola-Vilenkin type spacetime
Bivash Majumder, Goutam Manna, Ashoke Das
For a particular type of {\bf k-}essence scalar field, the {\bf k-}essence emergent gravity metric is exactly mapped on to the Barriola-Vilenkin (BV) type metric for Schwarzschild…
Thermodynamics for the k-essence Emergent Reissner-Nordstrom-de Sitter Spacetime
Goutam Manna, Bivash Majumder, Ashoke Das
The {\bf k-}essence emergent Reissner-Nordstrom-de Sitter spacetime has exactly mapped on to the Robinson-Trautman (RT) type spacetime with cosmological constant for certain co…
Supersymmetry and the Riemann zeros on the critical line
Ashok Das, Pushpa Kalauni
We propose a new way of studying the Riemann zeros on the critical line using ideas from supersymmetry. Namely, we construct a supersymmetric quantum mechanical model whose energy…
Bogoliubov transformation and the thermal operator representation in the real time formalism
Ashok Das, Atri Deshamukhya, Pushpa Kalauni +1
It has been shown earlier \cite{brandt,brandt1} that, in the mixed space, there is an unexpected simple relation between any finite temperature graph and its zero temperature count…
Fermion propagator in an external potential and generalized Airy functions
A. L. M. Britto, Ashok K. Das, J. Frenkel
We study the behavior of the fermion propagator in an external time dependent potential in 0+1 dimension. We show that, when the potential has upto quadratic terms in time, the pro…
Testing Dark Matter with the Anomalous Magnetic Moment in Quantum Electrodynamics Model
Ashok K. Das, Jorge Gamboa, Fernando Méndez +1
We consider a model of dark quantum electrodynamics which is coupled with a visible photon through a kinetic mixing term. After checking of consistency properties, we compute the $…
