On the viability of minimal HoÅava gravity
Ted Jacobson, Pranav Pulakkat
HoÅava gravity is a Lorentz-violating modification of general relativity (GR) with a preferred spacelike foliation. Observational evidence has put strong constraints on the parame…

Dressed Subsystems in Classical Gravity
Pranav Pulakkat
This paper considers the problem of consistently defining subsystems in gravitational theories. It is argued that a subsystem is a spacetime subregion in which the observables form…

On the Charge Algebra of Causal Diamonds in Three Dimensional Gravity
Pranav Pulakkat
Covariant phase space methods are applied to the analysis of a causal diamond in 2+1-dimensional pure Einstein gravity. It is found that the reduced phase space is parametrized by…
