Memory Effects and Entanglement Dynamics of Finite time Acceleration
Nitesh K. Dubey, Sanved Kolekar
We construct a smooth trajectory in Minkowski spacetime that is inertial in the asymptotic past and future but undergoes approximately uniform acceleration for a finite duration. I…
Isentropic processes for axisymmetric Black Holes
Nitesh K. Dubey, Sanved Kolekar
We demonstrate that the isentropic absorption of a classical charged test particle is classically forbidden for all 3+1 dimensional stationary, non-extremal, axisymmetric black hol…
Harvesting Fermionic Field Entanglement in Schwarzschild Spacetime
Nitesh Kumar Dubey, Sanved Kolekar
We explore entanglement harvesting using two Unruh-DeWitt (UDW) detectors linearly coupled to the scalar density of a massless spin-1/2 field in 1+1 Schwarzschild spacetime. We con…
Wigner distributions in Rindler spacetime and nonvacuum Minkowski states
Nitesh K. Dubey, Sanved Kolekar
In the 1970s, Fulling, Davies, and Unruh demonstrated that the vacuum state perceived by an inertial observer in Minkowski space appears as a thermal bath to a uniformly accelerate…
