Thermality from a Rindler quench (2018)
Journal Article
Louko, J. (2018). Thermality from a Rindler quench. Classical and Quantum Gravity, 35(20), 1-13. https://doi.org/10.1088/1361-6382/aadb34

© 2018 IOP Publishing Ltd. Ultracold fermionic atoms in an optical lattice, with a sudden position-dependent change (a quench) in the effective dispersion relation, have been proposed by Rodríguez-Laguna et al as an analogue spacetime test of the Unr...

Smooth and sharp creation of a spherical shell for a (3+1)-dimensional quantum field (2018)
Journal Article
Carrington, M. E., Kunstatter, G., Louko, J., & Zhou, L. J. (2018). Smooth and sharp creation of a spherical shell for a (3+1)-dimensional quantum field. Physical Review D, 98(2), https://doi.org/10.1103/PhysRevD.98.024035

We study the creation of a spherical, finite radius source for a quantized massless scalar field in 3 þ 1 dimensions. The goal is to model the breakdown of correlations that has been proposed to occur at the horizon of an evaporating black hole. We d...

Dynamical obstruction to perpetual motion from Lorentz-violating black holes (2018)
Journal Article
Benkel, R., Bhattacharyya, J., Louko, J., Mattingly, D., & Sotiriou, T. P. (2018). Dynamical obstruction to perpetual motion from Lorentz-violating black holes. Physical Review D, 98(2), Article 024034. https://doi.org/10.1103/PhysRevD.98.024034

Black holes in Lorentz-violating theories have been claimed to violate the second law of thermodynamics by perpetual motion energy extraction. We revisit this question for a Penrose splitting process in a spherically symmetric setting with two specie...

Quantum fields during black hole formation: how good an approximation is the Unruh state? (2018)
Journal Article
Juárez-Aubry, B. A., & Louko, J. (in press). Quantum fields during black hole formation: how good an approximation is the Unruh state?. Journal of High Energy Physics, 2018(5), https://doi.org/10.1007/JHEP05%282018%29140

We study the quantum effects of a test Klein-Gordon field in a Vaidya space-time consisting of a collapsing null shell that forms a Schwazschild black hole, by explicitly obtaining, in a (1 + 1)-dimensional model, the Wightman function, the renormali...

Quantum memory for Rindler supertranslations (2018)
Journal Article
Kolekar, S., & Louko, J. (2018). Quantum memory for Rindler supertranslations. Physical Review D, 97(8), https://doi.org/10.1103/PhysRevD.97.085012

The Rindler horizon in Minkowski spacetime can be implanted with supertranslation hair by a matter shock wave without planar symmetry, and the hair is observable as a supertranslation memory on the Rindler family of uniformly linearly accelerated obs...

Low-energy Lorentz violation from high-energy modified dispersion in inertial and circular motion (2018)
Journal Article
Louko, J., & Upton, S. D. (2018). Low-energy Lorentz violation from high-energy modified dispersion in inertial and circular motion. Physical Review D, 97(2), Article 025008. https://doi.org/10.1103/PhysRevD.97.025008

© 2018 American Physical Society. We consider an Unruh-DeWitt detector in inertial and circular motion in Minkowski spacetime of arbitrary dimension, coupled to a quantized scalar field with the Lorentz-violating dispersion relation ω=|k|f(|k|/M†), w...
