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. …”

An optimal transport formulation of the Einstein equations of general relativity by Mondino, A, Suhr, S

“…The result gives a new connection between general relativity and optimal transport; moreover, it gives a mathematical reinforcement of the strong link between general relativity and thermodynamics/information theory that emerged in the physics literature of the last years. …”

Large data problems in fluid dynamics and general relativity by Athanasiou, N

“…</p> <p>The second project developed in this thesis shifts focus from the area of conservation laws to that of mathematical General Relativity. We provide, in joint work with Xinliang An, a trapped surface formation criterion for the Einstein–Maxwell system where the right–hand side corresponds to the Maxwell energy–momentum tensor that models electromagnetic effects.…”

Quantum interference in external gravitational fields beyond General Relativity by Luca Buoninfante, Gaetano Lambiase, Luciano Petruzziello

“…We work in the context of generalized quadratic theories of gravity to compare their physical predictions with the analogous outcomes in general relativity. In so doing, we show that the decoherence rate strongly depends on the gravitational model under investigation, which means that this approach turns out to be a promising test bench to probe and discriminate among all the extensions of Einstein’s theory in future experiments.…”
