On Cosmological Implications of Gravitational Trace Anomaly
Neven Bilic, Branko Guberina, Raul Horvat +2
We study the infrared effective theory of gravity that stems from the quantum trace anomaly. Quantum fluctuations of the metric induce running of the cosmological constant and the…
Cosmologies with variable parameters and dynamical cosmon: implications on the cosmic coincidence problem
Javier Grande, Joan Sola, Hrvoje Stefancic
Dynamical dark energy (DE) has been proposed to explain various aspects of the cosmological constant (CC) problem(s). For example, it is very difficult to accept that a strictly co…
What is there in the black box of dark energy: variable cosmological parameters or multiple (interacting) components?
Javier Grande, Joan Sola, Hrvoje Stefancic
The coincidence problems and other dynamical features of dark energy are studied in cosmological models with variable cosmological parameters and in models with the composite dark…
