Space- vs Time-dependence in taming the infrared instability of projectable Hořava 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…
Asymptotic freedom in (3+1)-dimensional projectable Horava gravity: connecting ultraviolet to infrared
Andrei O. Barvinsky, Alexander V. Kurov, Sergey M. Sibiryakov
We investigate the renormalization group flow of projectable Horava gravity in dimensions generated by marginal operators with respect to the Lifshitz scaling. The flow pos…
Scattering amplitudes in high-energy limit of projectable Horava gravity
Jury I. Radkovski, Sergey M. Sibiryakov
We study the high-energy limit of projectable Ho\v rava gravity using on-shell graviton scattering amplitudes. We compute the tree-level amplitudes using symbolic computer algebra…
Black hole induced false vacuum decay: The role of greybody factors
Andrey Shkerin, Sergey Sibiryakov
We study false vacuum decay catalyzed by black holes. We consider a toy two-dimensional model of a scalar field with an unstable potential in the background of a dilaton black hole…
Beta functions of (3+1)-dimensional projectable Horava gravity
Andrei O. Barvinsky, Alexander V. Kurov, Sergey M. Sibiryakov
We derive the full set of beta functions for the marginal essential couplings of projectable Horava gravity in (3 + 1)-dimensional spacetime. To this end we compute the divergent p…
Black hole induced false vacuum decay from first principles
Andrey Shkerin, Sergey Sibiryakov
We provide a method to calculate the rate of false vacuum decay induced by a black hole. The method uses complex tunneling solutions and consistently takes into account the structu…
