DOI: 10.1088/1361-6382/aa9fd5
Abstract: The variety of consistent ‘gauging’ deformations of supergravity theories in four dimensions depends on the choice of Lagrangian formulation. One important goal is to get the most general deformations without making hidden assumptions. Ignoring supersymmetry… read more here.

DOI: 10.1088/1475-7516/2018/07/048
Abstract: The observation of GW170817 in both gravitational and electromagnetic waves provides a number of unique tests of general relativity. Certain modifications of gravity involve the presence of additional spacetime dimensions. In these models, as the… read more here.

DOI: 10.1103/physrevd.95.106005
Abstract: We discuss some aspects of soft hairy black holes and a new kind of "soft hairy cosmologies", including a detailed derivation of the metric formulation, results on flat space, and novel observations concerning the entropy.… read more here.

DOI: 10.1103/physrevd.97.024036
Abstract: We investigate the gravitational memory effect for linearized perturbations off of Minkowski space in odd spacetime dimensions $d$ by examining the effects of gravitational radiation from classical point particle scattering. We also investigate analogous memory… read more here.

DOI: 10.1103/physrevlett.130.111603
Abstract: We establish the irreversibility of renormalization group flows on a pointlike defect inserted in a d-dimensional Lorentzian conformal field theory. We identify the impurity entropy g with the quantum relative entropy in two equivalent ways.… read more here.
