Gravity-Informed Neural Networks for Post-Newtonian Binary Dynamics
Gabriele Barbagallo, Javier Matulich
We introduce a gravity-informed neural-network (GravINNs) framework for learning post-Newtonian binary orbital dynamics. The method incorporates the equations of motion directly in…
Maxwell Chern-Simons gravity in 3D: Thermodynamics of cosmological solutions and black holes with torsion
Luis Avilés, Patrick Concha, Javier Matulich +2
We construct generalized sets of asymptotic conditions for both three-dimensional Maxwell Chern-Simons gravity and a novel extension that incorporates torsion through a deformation…

Patrick Concha, Javier Matulich, Daniel Pino +1
In this work we analyze the asymptotic symmetries of the three-dimensional Chern-Simons (CS) gravity theory for a higher spin extension of the so-called Maxwell algebra. We propose…
Superrotations at Spacelike Infinity
Adrien Fiorucci, Javier Matulich, Romain Ruzziconi
We propose a consistent set of boundary conditions for gravity in asymptotically flat spacetime at spacelike infinity, which yields an enhancement of the Bondi-Metzner Sachs group…

In this paper we analyze the asymptotic symmetries of the three-dimensional Chern-Simons supergravity for a supersymmetric extension of the semi-simple enlargement of the Poincaré…
Singular limits of spacetimes and their isometries
Eric Bergshoeff, Javier Matulich, Tomás Ortín
We consider spacetime metrics with a given (but quite generic) dependence on a dimensionful parameter such that in the 0 and infinity limits of that parameter the metric becomes si…

Local supersymmetry and the square roots of Bondi-Metzner-Sachs supertranslations
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
Super-BMS algebras -- also called BMS superalgebras -- are graded extensions of the BMS algebra. They can be of two different types: they can contain either a finite nu…
