Unruh-DeWitt Fermion Detector on a (1+1)-Dimensional Cylindrical Spacetime: Arbitrary Worldlines and Inequivalent Spin Structures (2017)
Conference Proceeding

We examine an Unruh-DeWitt particle detector which couples linearly to the scalar density of a massless Dirac field on the static cylindrical quotient of the (1+1)-dimensional Minkowski spacetime, allowing the detector’s motion to remain arbitrary and...

Gravitational memory for uniformly accelerated observers (2017)
Journal Article

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

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

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

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...
