Hawking-Page phase transition for pure Lovelock black holes

Nitesh K. Dubey, Sanved Kolekar

We investigate the thermodynamic properties of static, spherically symmetric Anti-de Sitter (AdS) black holes, focusing on the interplay between characteristic temperatures, as wel…

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…

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…
