Effective Goldstone dynamics on cosmological space-times
Marc Schneider
We derive the Lehmann-Symanzik-Zimmermann reduction formalism for a massive spin-2 particle on Minkowski spacetime and extend the formalism to cosmological spacetimes. The reductio…
Hawking radiation with dispersion: reconciling the Bogoliubov and tunneling approaches
Francesco Del Porro, Stefano Liberati, Marc Schneider
We investigate Hawking-like particle production in analogue gravity systems with superluminal modified dispersion relations. For a broad class of even, convex, and polynomially bou…
Probing of colliding wave spacetimes and a quantum Weyl conjecture
Ivo Sachs, Marc Schneider
We perform a quantum probing of colliding plane-wave space-times. In particular, we consider the Khan-Penrose and the Ferrari-Ibáñez solutions, which admit a strong and a weak sing…
A local diagnostic program for unitary evolution in general space-times
Ka Hei Choi, Stefan Hofmann, Marc Schneider
We present a local framework for investigating non-unitary evolution groups pertinent to effective field theories in general semi-classical spacetimes. Our approach is based on a r…
On the Resilience of Black Hole Evaporation: Gravitational Tunneling through Universal Horizons
M. Schneider, F. Del Porro, M. Herrero-Valea +1
Using a quantum tunneling derivation, we show the resilience of Hawking radiation in Lorentz violating gravity. In particular, we show that the standard derivation of the Hawking e…
Gravitational Tunneling in Lorentz Violating Gravity
F. Del Porro, M. Herrero-Valea, S. Liberati +1
Black holes in Lorentz violating gravity, such as Einstein--Aether or Horava--Lifshitz Gravity, are drastically different from their general relativistic siblings. Although they al…
