Alleviation of anomalies from the non-oscillatory vacuum in loop quantum cosmology
Mercedes MartÃn-Benito, Rita B. Neves, Javier Olmedo
In this work we investigate observational signatures of a primordial power spectrum with exponential infrared suppression, motivated by the choice of a non-oscillatory vacuum in a…

Hawking radiation from an analogue bouncing geometry
Alberto GarcÃa MartÃn-Caro, Gerardo GarcÃa-Moreno, Javier Olmedo +1
We propose a setting that simulates Hawking radiation from an analogue bouncing geometry, i.e., a collapsing geometry that reverts its collapse after a finite time, in a setup cons…
