Schrödinger Symmetry in Gravitational Mini-Superspaces
Jibril Ben Achour, Etera R. Livine, Daniele Oriti +1
We prove that the simplest gravitational symmetry reduced models describing cosmology and black holes mechanics are invariant under the Schrödinger group. We consider the flat FRW…

Hidden symmetry of the static response of black holes: Applications to Love numbers
Jibril Ben Achour, Etera R. Livine, Shinji Mukohyama +1
We show that any static linear perturbations around Schwarzschild black holes enjoy a set of conserved charges which forms a centrally extended Schrödinger algebra sh(1) = sl$(2,\m…
