The First Law of Black Hole Mechanics for Fields with Internal Gauge Freedom
Kartik Prabhu
We derive the first law of black hole mechanics for physical theories based on a local, covariant and gauge-invariant Lagrangian where the dynamical fields transform non-trivially…
Curved non-relativistic spacetimes, Newtonian gravitation and massive matter
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
There is significant recent work on coupling matter to Newton-Cartan spacetimes with the aim of investigating certain condensed matter phenomena. To this end, one needs to have a c…
Fields and fluids on curved non-relativistic spacetimes
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
We consider non-relativistic curved geometries and argue that the background structure should be generalized from that considered in previous works. In this approach the derivative…
Black Hole Instabilities and Exponential Growth
Kartik Prabhu, Robert M. Wald
Recently, a general analysis has been given of the stability with respect to axisymmetric perturbations of stationary-axisymmetric black holes and black branes in vacuum general re…
