Space- vs Time-dependence in taming the infrared instability of projectable HoÅava Gravity
Shinji Mukohyama, Jury Radkovski, Sergey Sibiryakov
Minkowski spacetime exhibits infrared instability in projectable Ho\v rava gravity in (3+1) dimensions. To be phenomenologically viable, the instability should be either hidden by…

Fixing EFT equations with a reservoir model
A. Besharat, L. Lehner, J. Radkovski
Effective Field Theories with higher derivatives often yield equations of motion which define ill-posed problems. We present a method for enhancing control on such theories by coup…

Quantizing non-projectable HoÅava gravity with Lagrangian path integral
D. Blas, F. Del Porro, M. Herrero-Valea +2
We formulate the quantum version of non-projectable HoÅava gravity as a Lagrangian theory with a path integral in the configuration space with an ultra-local in time, but non-loca…
