How hot are expanding universes ?
Nathaniel Obadia
A way to address the conundrum of Quantum Gravity is to illustrate the potentially fundamental interplay between quantum field theory, curved space-times physics and thermodynamics…

Unruh Effect for General Trajectories
N. Obadia, M. Milgrom
We consider two-level detectors coupled to a scalar field and moving on arbitrary trajectories in Minkowski space-time. We first derive a generic expression for the response functi…

Moving Detectors in Cavities
Nathaniel Obadia
We consider two-level detectors, coupled to a quantum scalar field, moving inside cavities. We highlight some pathological resonant effects due to abrupt boundaries, and decide to…
