Particles and their fluids in nontrivial matter extensions to general relativity by P.P. Avelino

“…According to the standard von Laue condition, the volume-averaged pressure inside particles of fixed mass and structure vanishes in the Minkowski limit of general relativity. Here we show that this condition is in general not fulfilled in the context of f(R,T) gravity, or of other theories of gravity in which the linear momentum is not conserved in this limit (here, R and T represent the Ricci scalar and the trace of the energy-momentum tensor, respectively). …”

General relativity from three-forms in seven dimensions by Kirill Krasnov

“…We show that the resulting 4D theory is (Riemannian) General Relativity (GR) in Plebanski formulation, modulo corrections that are negligible for curvatures smaller than Planckian. …”

Mapping nonlinear gravity into General Relativity with nonlinear electrodynamics by Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi, Diego Rubiera-Garcia

“…Abstract We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into general relativity (GR) coupled to another nonlinear theory of electrodynamics. …”

Generalized Uncertainty Principle, Classical Mechanics, and General Relativity by Roberto Casadio, Fabio Scardigli

“…The Generalized Uncertainty Principle (GUP) has been directly applied to the motion of (macroscopic) test bodies on a given space-time in order to compute corrections to the classical orbits predicted in Newtonian Mechanics or General Relativity. These corrections generically violate the Equivalence Principle. …”

Bound on Photon Circular Orbits in General Relativity and Beyond by Sumanta Chakraborty

“…In this work, we derive bounds on the location of the photon circular orbit around compact objects within the purview of general relativity and beyond. As we have explicitly demonstrated, contrary to the earlier results in the context of general relativity, the bound on the location of the photon circular orbit is not necessarily an upper bound. …”

Cosmological Tests of General Relativity with Future Tomographic Surveys by Zhao, Gong-Bo, Pogosian, Levon, Silvestri, Alessandra, Zylberberg, Joel

“…Future weak lensing surveys will map the evolution of matter perturbations and gravitational potentials, yielding a new test of general relativity on cosmic scales. They will probe the relations between matter overdensities, local curvature, and the Newtonian potential. …”
