Hamiltonian analysis of mimetic scalar gravity revisited
Alexander Ganz, Purnendu Karmakar, Sabino Matarrese +1
We perform the Hamiltonian analysis of several mimetic gravity models and compare our results with those obtained previously by different authors. We verify that for healthy mimeti…

Gravity in mimetic scalar-tensor theories after GW170817
Alexander Ganz, Nicola Bartolo, Purnendu Karmakar +1
We derive the most general mimetic scalar-tensor theory assuming a healthy "seed" action and accounting for the constraints on the speed of gravitational-wave propagation arising f…
