Harvesting Information Across the Horizon

S. Wang, M. R. Preciado Rivas, R. B. Mann

The effect of black holes on entanglement harvesting has been of considerable interest over the past decade. Research involving stationary Unruh-DeWitt (UDW) detectors near a (2+1)…

Deep in the knotted black hole

Massimiliano Spadafora, Manar Naeem, María R. Preciado-Rivas +2

We consider the transition rate of a freely falling Unruh-DeWitt detector, coupled linearly to a massless scalar quantum field prepared in the Hartle-Hawking-Israel state, as a pro…

Accelerated detector in a superposed spacetime

Lakshay Goel, Everett A. Patterson, María Rosa Preciado-Rivas +3

In pursuit of a full-fledged theory of quantum gravity, operational approaches offer insights into quantum-gravitational effects produced by quantum superposition of different spac…
