The generalized second law as a thermodynamic selection criterion for dynamical dark energy
Marcos H. Cruz, Miguel Cruz, Joel Saavedra +1
The growing number of generalized horizon entropy proposals has led to a wide variety of modified cosmological models, yet there is currently no general physical principle capable…
Rotating traversable wormholes and particle dynamics in gravity
G. G. L. Nashed, Waleed El Hanafy, Amare Abebe +2
Traversable wormholes are among the most interesting solutions of gravitational theories, but within General Relativity they generally require exotic matter violating the null ener…
Cosmologically viable non-polynomial quasi-topological gravity: explicit models, CDM limit and observational constraints
Emmanuel N. Saridakis
We investigate the cosmological implications of non-polynomial quasi-topological gravity (NPQTG), a novel class of modified gravitational theories in which the background dynamics…
Accelerating scaling solutions from dark matter particle creation
Sudip Halder, Jaume de Haro, Supriya Pan +3
This article opens new window to obtain accelerating scaling attractors without any need of dark energy. We study cosmological dynamics in a two-fluid system where pressureless dar…
Primordial black hole formation from transient cosmology
Gerasimos Kouniatalis, Theodoros Papanikolaou, Spyros Basilakos +1
We study primordial black hole (PBH) formation in a minimally coupled teleparallel cosmology that generates a transient departure from standard radiation domination. The mod…
New modified cosmology from a new generalized entropy
G. G. Luciano, E. N. Saridakis
We develop new modified cosmological scenarios by applying the first law of thermodynamics at the Universe horizon, utilizing a new entropic functional that generalizes the standar…
Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mubasher Jamil, Emmanuel N. Saridakis
Extreme mass-ratio inspirals (EMRIs) are among the most powerful probes of strong-field gravity and of the environments surrounding supermassive compact objects. Motivated by the e…
