Stationary Stars Are Axisymmetric in Higher Curvature Gravity
Nitesh K. Dubey, Sanved Kolekar, Sudipta Sarkar
The final equilibrium stage of stellar evolution can result in either a black hole or a compact object such as a white dwarf or neutron star. In general relativity, both stationary…
Quantum Field Theory in Successive Rindler Spacetimes
Nitesh K. Dubey, Jaswanth Uppalapati, Sanved Kolekar
We study successive Rindler-like transformations in Minkowski spacetime and the corresponding sequence of vacuum states perceived by observers restricted to respective wedges. Exte…
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…
