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…
Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mustapha Azreg-Aïnou, Mubasher Jamil +1
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…
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…
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…
Effective matter sectors from modified entropies
Ankit Anand, Sahil Devdutt, Kimet Jusufi +1
We present a general formalism linking modified entropy functions directly to a modified spacetime metric and, subsequently, to an effective matter sector of entropic origin. In pa…
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…
