Black-hole radiation in Bose-Einstein condensates
Jean Macher, Renaud Parentani
We study the phonon fluxes emitted when the condensate velocity crosses the speed of sound, i.e., in backgrounds which are analogous to that of a black hole. We focus on elongated…
Black/White hole radiation from dispersive theories
Jean Macher, Renaud Parentani
We study the fluxes emitted by black holes when using dispersive field theories. We work with stationary one dimensional backgrounds which are asymptotically flat on both sides of…
Signatures of trans-Planckian dispersion in inflationary spectra
Jean Macher, Renaud Parentani
The primordial spectra are calculated using dispersion relations which deviate from the relativistic one above a certain energy scale Lambda. We determine the properties of the lea…
Phase Transitions In Compact Stars
Jean Macher, Jurgen Schaffner-Bielich
We report on a three--month research project for undergraduate students about the mass-radius relation of compact stars. The equation of state used is constrained at low densities…
