Group theoretical approach to quantum fields in de Sitter space I. The principal series
E. Joung, J. Mourad, R. Parentani
Using unitary irreducible representations of the de Sitter group, we construct the Fock space of a massive free scalar field. In this approach, the vacuum is the unique dS invarian…

Hawking Radiation from Acoustic Black Holes, Short Distance and Back-Reaction Effects
R. Balbinot, A. Fabbri, S. Fagnocchi +1
Using the action principle we first review how linear density perturbations (sound waves) in an Eulerian fluid obey a relativistic equation: the d'Alembert equation. This analogy b…
