Einstein's General Relativity (GR) is possibly one of the greatest intellectual achievements
ever conceived by the human mind. In fact, over the last century, GR has proven to be an …

We propose an extension of the symmetric teleparallel gravity, in which the gravitational
action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter …

Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

Morris and Thorne developed wormhole solutions in the late 1980s when they discovered a
recipe that wormholes must follow for travelers to cross them safely. They describe exotic …

We consider the Palatini formulation of f (R, T) gravity theory, in which a non-minimal
coupling between the Ricci scalar and the trace of the energy-momentum tensor is …

Recent advances in nuclear theory and new astrophysical observations have led to the
need for specific theoretical models applicable to dense-matter physics phenomena …

In this work, we studied the slow-roll approximation of cosmic inflation within the context of f
(R, T) gravity, where R is the scalar curvature, and T is the trace of the energy–momentum …

We consider an extension of standard General Relativity in which the Hilbert–Einstein action
is replaced by an arbitrary function of the Ricci scalar, nonmetricity, torsion, and the trace of …

We investigate the equilibrium and radial stability of spherically symmetric relativistic stars,
considering a polytropic equation of state (EoS), within the framework of f (R, T) gravity with …

We generalize and unify the f R, T and f R, L m type gravity models by assuming that the
gravitational Lagrangian is given by an arbitrary function of the Ricci scalar R, of the trace of …
