Herglotz-type gravity

Marek Wazny, Lehel Csillag, Miguel A. S. Pinto +1

The non-conservation of the energy-momentum tensor in gravity can be interpreted as an effective manifestation of dissipation. Motivated by this, we propose a new formulat…

Modified Gravity with Nonminimal Curvature-Matter Couplings: A Framework for Gravitationally Induced Particle Creation

Francisco S. N. Lobo, Tiberiu Harko, Miguel A. S. Pinto

Modified gravity theories with a nonminimal coupling between curvature and matter offer a compelling alternative to dark energy and dark matter by introducing an explicit interacti…

Energy-Momentum Squared Gravity: A Brief Overview

Ricardo A. C. Cipriano, Nailya Ganiyeva, Tiberiu Harko +3

In this work, we present a review of Energy-Momentum Squared Gravity (EMSG) -- more specifically, gravity, where represents the Ricci scalar and de…

Matter really does matter, or Why type theories are significant for gravitational physics and cosmology

Tiberiu Harko, Miguel A. S. Pinto, Shahab Shahidi

In a recent paper (Lacombe, Mukohyama, and Seitz, JCAP {\bf 2024}, 05, 064 (2024)), the authors provided an in-depth analysis of a class of modified gravity theories, generally cal…

Gravitationally induced matter creation in scalar-tensor gravity

Ricardo A. C. Cipriano, Tiberiu Harko, Francisco S. N. Lobo +2

In this work, we analyze the possibility of gravitationally induced matter creation in the so-called Energy-Momentum-Squared gravity (EMSG), i.e. gravity, in it…

Observational Constraints and Cosmological Implications of Scalar-Tensor Gravity

Amine Bouali, Himanshu Chaudhary, Tiberiu Harko +3

Recently, the scalar-tensor representation of gravity was used to explore gravitationally induced particle production/annihilation. Using the framework of irreversible th…

Irreversible Geometrothermodynamics of Open Systems in Modified Gravity

Miguel A. S. Pinto, Tiberiu Harko, Francisco S. N. Lobo

In this work, we explore the formalism of the irreversible thermodynamics of open systems and the possibility of gravitationally generated particle production in modified gravity.…

Gravitationally induced particle production in scalar-tensor gravity

Miguel A. S. Pinto, Tiberiu Harko, Francisco S. N. Lobo

We explore the possibility of gravitationally generated particle production in the scalar-tensor representation of gravity. Due to the explicit nonminimal curvature-matter…
