Metastable Dark Energy on the Phantom Brane
Purba Mukherjee, Arman Shafieloo, Varun Sahni +1
Recent DESI observations hint at a preference for dynamical dark energy with an equation of state (EoS) that crosses the phantom divide at . In this work, we investigate \tex…
Effective scalaron--photon interaction in gravity
Yuri Shtanov
We revisit the effective coupling of the scalaron to gauge fields in gravity minimally coupled to the Standard Model, focusing on the scalaron decay into two photons. Treati…
Sagnac and Mashhoon effects in graphene
Yu. V. Shtanov, T. -H. O. Pokalchuk, S. G. Sharapov
We investigate the Sagnac and Mashhoon effects in graphene, taking into account both the pseudospin and intrinsic spin of electrons, within a simplified model of a rotating nanotub…
Braneworld Dark Energy in light of DESI DR2
Swagat S. Mishra, William L. Matthewson, Varun Sahni +2
Recent observational results from the DESI collaboration reveal tensions with the standard CDM model and favour a scenario in which dark energy (DE) decays over time. The DESI D…
Interactions of the scalaron dark matter in gravity
Yuri Shtanov, Yurii Sheiko
In gravity, the scalaron -- a scalar degree of freedom arising from modification of General Relativity -- could account for all dark matter in the universe if its mass lies…
Scalaron dark matter and the thermal history of the universe
Yuri Shtanov
In metric gravity minimally coupled to the Standard Model, the scalaron field can act as a dark-matter candidate if its mass lies in the range $\text{meV} \lesssim m \lesssi…
