The Integrated Sachs-Wolfe Effect in Interacting Dark Energy Models
German Olivares, Fernando Atrio-Brandela, Diego Pavon
Models with dark energy decaying into dark matter have been proposed in Cosmology to solve the coincidence problem. We study the effect of such coupling on the cosmic microwave bac…
Dynamics of Interacting Quintessence Models: Observational Constraints
German Olivares, Fernando Atrio-Barandela, Diego Pavon
Interacting quintessence models have been proposed to explain or, at least, alleviate the coincidence problem of late cosmic acceleration. In this paper we are concerned with two a…
The matter power spectrum as a tool to discriminate dark matterr-dark energy interactions
German Olivares, Diego Pavon, Fernando Atrio-Barandela
The coincidence problem of late cosmic acceleration gets significantly alleviated when a suitable interaction between matter and dark energy, either of phantom type or not, enters…
Matter density perturbations in interacting quintessence models
G. Olivares, F. Atrio-Barandela, D. Pavon
Models with dark energy decaying into dark matter have been proposed to solve the coincidence problem in cosmology. We study the effect of such coupling in the matter power spectru…
Interacting models of soft coincidence
Sergio del Campo, Ramon Herrera, German Olivares +1
The coincidence problem of late cosmic acceleration is a serious riddle in connection with our understanding of the evolution of the Universe. In this paper we show that an interac…
Decoherence assisting a measurement-driven quantum evolution process
L. Roa, G. Olivares
We study the problem of driving an unknown initial mixed quantum state onto a known pure state without using unitary transformations. This can be achieved, in an efficient manner,…
