We present and utilize a simple formalism for the smooth creation of boundary conditions within relativistic quantum field theory. We consider a massless scalar field in (1 + 1)-dimensional flat spacetime and imagine smoothly transitioning from there...

Ideal clocks - A convenient fiction (2015)
Journal Article
Lorek, K., Louko, J., & Dragan, A. (2015). Ideal clocks - A convenient fiction. Classical and Quantum Gravity, 32(17), Article 175003. https://doi.org/10.1088/0264-9381/32/17/175003

© 2015 IOP Publishing Ltd. We show that no device built according to the rules of quantum field theory can measure proper time along its path. Highly accelerated quantum clocks experience the Unruh effect, which inevitably influences their time rate.... Read More about Ideal clocks - A convenient fiction.

(1+1)D calculation provides evidence that quantum entanglement survives a firewall (2015)
Journal Article
Martín-Martínez, E., & Louko, J. (2015). (1+1)D calculation provides evidence that quantum entanglement survives a firewall. Physical Review Letters, 115(3), Article 031301. https://doi.org/10.1103/PhysRevLett.115.031301

We analyze how preexisting entanglement between two Unruh-DeWitt particle detectors evolves when one of the detectors falls through a Rindler firewall in (1+1)-dimensional Minkowski space. The firewall effect is minor and does not wash out the detect... Read More about (1+1)D calculation provides evidence that quantum entanglement survives a firewall.

© 2015 American Physical Society. We study analytically the time-dependent boundary conditions of superconducting microwave circuit experiments in the high plasma frequency limit, in which the conditions are Robin-type and relate the value of the fie...

Renormalized vacuum polarization on rotating warped AdS3 black holes (2015)
Journal Article
Ferreira, H. R., & Louko, J. (2015). Renormalized vacuum polarization on rotating warped AdS3 black holes. Physical Review D, 91(2), Article 024038. https://doi.org/10.1103/PhysRevD.91.024038

We compute the renormalized vacuum polarization of a massive scalar field in the Hartle-Hawking state on (2+1)-dimensional rotating, spacelike stretched black hole solutions to topologically massive gravity, surrounded by a Dirichlet mirror that make...
