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…
