Gravitational memory for uniformly accelerated observers (2017)
Journal Article
Kolekar, S., & Louko, J. (2017). Gravitational memory for uniformly accelerated observers. Physical Review D, 96(2), Article 024054. https://doi.org/10.1103/PhysRevD.96.024054

Recently, Hawking, Perry and Strominger described a physical process that implants supertranslational hair on a Schwarzschild black hole by an infalling matter shock wave without spherical symmetry. Using the Bondi-Metzner-Sachs-type symmetries of th... Read More about Gravitational memory for uniformly accelerated observers.

Degenerate detectors are unable to harvest spacelike entanglement (2017)
Journal Article
Pozas-Kerstjens, A., Louko, J., & Martín-Martínez, E. (2017). Degenerate detectors are unable to harvest spacelike entanglement. Physical Review D, 95(10), https://doi.org/10.1103/PhysRevD.95.105009

We show, under a very general set of assumptions, that pairs of identical particle detectors in spacelike separation, such as atomic probes, can only harvest entanglement from the vacuum state of a quantum field when they have a nonzero energy gap. F... Read More about Degenerate detectors are unable to harvest spacelike entanglement.

Quantum communications and quantum metrology in the spacetime of a rotating planet (2017)
Journal Article
Kohlrus, J., Bruschi, D. E., Louko, J., & Fuentes, I. (2017). Quantum communications and quantum metrology in the spacetime of a rotating planet. EPJ Quantum Technology, 4, Article 7. https://doi.org/10.1140/epjqt/s40507-017-0061-0

We study how quantum systems that propagate in the spacetime of a rotating planet are affected by the curved background. Spacetime curvature affects wavepackets of photons propagating from Earth to a satellite, and the changes in the wavepacket encod...

Smooth and sharp creation of a pointlike source for a (3+1)-dimensional quantum field (2017)
Journal Article
Zhou, L., Carrington, M. E., Kunstatter, G., & Louko, J. (2017). Smooth and sharp creation of a pointlike source for a (3+1)-dimensional quantum field. Physical Review D, 95(8), https://doi.org/10.1103/PhysRevD.95.085007

We analyze the smooth and sharp creation of a pointlike source for a quantized massless scalar field in (3+1)-dimensional Minkowski spacetime, as a model for the breakdown of correlations that has been proposed to occur at the horizon of an evaporati...
