Microscopic entropy of static black holes in 3d Lovelock gravities
Gokhan Alkac, Luis Guajardo, Hikmet Ozsahin
We give a microscopic derivation of the semi-classical entropy of static black holes in 3d Lovelock gravities, which are certain 3d Horndeski theories that were recently discovered…
Non-Noetherian conformal Cheshire effect
Eloy Ayón-Beato, Mokhtar Hassaine, Pedro A. Sánchez
The gravitational Cheshire effect refers to the possibility of turning off the gravitational field while still leaving an imprint of the nonminimal coupling of matter to gravity. T…
Global conformal symmetry in scalar-tensor theories
Eugeny Babichev, Christos Charmousis, Mokhtar Hassaine +1
We study a subclass of Horndeski gravity which has both global conformal and shift symmetries. Global symmetries are characterised by the presence of a conserved current which has…
Nonlinearly charging the conformally dressed black holes preserving duality and conformal invariance
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine
We start this paper by concisely rederiving ModMax, which is nothing but the unique nonlinear extension of Maxwell's equations preserving conformal and duality invariance. The meri…
