A remarkably simple theory of 3d massive gravity
Marc Geiller, Karim Noui
We propose and study a new action for three-dimensional massive gravity. This action takes a very simple form when written in terms of connection and triad variables, but the conne…
Cosmological evolution in DHOST theories
Marco Crisostomi, Kazuya Koyama, David Langlois +2
In the context of Degenerate Higher-Order Scalar-Tensor (DHOST) theories, we study cosmological solutions and their stability properties. In particular, we explicitly illustrate th…
"Shadowy" modes in Higher-Order Scalar-Tensor theories
Antonio De Felice, David Langlois, Shinji Mukohyama +2
We consider Higher-Order Scalar-Tensor theories which appear degenerate when restricted to the unitary gauge but are not degenerate in an arbitrary gauge. We dub them U-degenerate…
Polymer Schwarzschild black hole: An effective metric
Jibril Ben Achour, Frédéric Lamy, Hongguang Liu +1
We consider the modified Einstein equations obtained in the framework of effective spherically symmetric polymer models inspired by Loop Quantum Gravity. When one takes into accoun…
Mimetic gravity as DHOST theories
David Langlois, Michele Mancarella, Karim Noui +1
We show that theories of mimetic gravity can be viewed as degenerate higher-order scalar-tensor (DHOST) theories that admit an extra local (gauge) symmetry in addition to the usual…
