Modified gravity and cosmology with nonminimal (derivative) coupling between matter and the Einstein tensor
Petros Asimakis, Spyros Basilakos, Andreas Lymperis +2
We construct new classes of modified theories in which the matter sector couples with the Einstein tensor, namely we consider direct couplings of the latter to the energy-momentum…
Primordial black holes and gravitational waves from non-canonical inflation
Theodoros Papanikolaou, Andreas Lymperis, Smaragda Lola +1
Primordial black holes (PBHs) can generically form in inflationary setups through the collapse of enhanced cosmological perturbations, providing us access to the early Universe thr…
Late-time cosmology with phantom dark-energy in gravity
Andreas Lymperis
Motivated by the exciting features and a recent proposed general form of the function of non-metricity scalar Q, we investigate the cosmological implications in gravity, thr…
