In this work we study nonperturbatively the transmission of classical and quantum
information in globally hyperbolic spacetimes, where the communication channel is between …

A bstract In the present article, we study how different gravitational wave (GW) burst profiles
in linearized gravity, with and without the asymptotic memory, may influence the harvesting …

We study Unruh phenomena for a qudit detector coupled to a quantized scalar field,
comparing its response to that of a standard qubit-based Unruh-DeWitt detector. We show …

We derive the gravitational field and the spacetime metric generated by sources in quantum
superposition of different locations. We start by working in a Newtonian approximation, in …

A bstract It is well-known that the (1+ 1) dimensional Schwarzschild and spatially flat FLRW
spacetimes are conformally flat. This work examines entanglement harvesting from the …

Unruh DeWitt (UDW) detectors are important constructs in studying the dynamics of quantum
fields in any geometric background. Curvature also plays an important role in setting up the …

We propose an alternative form for the quantum master equation in the theory of open
quantum systems. This alternative formalism allows one to describe the dynamics of two …

This work considers two Unruh-DeWitt detectors interacting with a massless, minimally
coupled scalar field in a $(1+ 1) $ dimensional Reissner-Nordström black hole spacetime. In …

We investigate the heat properties of charged AdS black holes in the Gauss-Bonnet gravity
coupled with nonlinear electrodynamics. We consider the thermodynamics of black holes …

We investigate asymmetric steering harvesting phenomenon involving two non-identical
inertial detectors with different energy gaps, which interact locally with vacuum massless …
