When one sign is not enough: 2+1 circular motion Unruh effect at low energies
Leo J. A. Parry, Christopher J. Fewster, Jorma Louko
We address the circular motion Unruh effect in 2+1 spacetime dimensions, as probed by a pointlike Unruh-DeWitt detector coupled to a massless scalar field. The effective temperatur…
Back-action from inertial and non-inertial Unruh-DeWitt detectors revisited in covariant perturbation theory
Adam S. Wilkinson, Leo J. A. Parry, Jorma Louko +1
We investigate the back-action from a spatially pointlike particle detector on a quantum scalar field, as characterised by the expectation value of the field's stress-energy tensor…
Reply to 'Comment on "Ideal clocks -- a convenient fiction"'
Krzysztof Lorek, Jorma Louko, Andrzej Dragan
For a quantum scalar field that is confined in a uniformly linearly accelerated cavity in Minkowski spacetime and interacts linearly with a scalar field that is not confined in the…
Nondestructive optomechanical detection scheme for Bose-Einstein condensates
Cisco Gooding, Cameron R. D. Bunney, Samin Tajik +6
We present a two-tone heterodyne optical readout scheme to extract unequal-time density correlations along an arbitrary stationary interaction path from a pancake-shaped Bose-Einst…
Waiting around for Unruh
Leo J. A. Parry, Diego Vidal-Cruzprieto, Christopher J. Fewster +1
How long does a uniformly rotating observer need to interact with a quantum field in order to register an approximately thermal response due to the circular motion Unruh effect? We…
Expansion-sensitive coupling of a local quantum system in de Sitter cosmology
Jorma Louko, Guillermo A. Mena Marugán, Alvaro Torres-Caballeros
When a local quantum system couples to a quantum field in a cosmological spacetime, the time dependence of the coupling strength is conventionally taken to reflect the design of th…
