Invertible field transformations with derivatives: necessary and sufficient conditions
Eugeny Babichev, Keisuke Izumi, Norihiro Tanahashi +1
We formulate explicitly the necessary and sufficient conditions for the local invertibility of a field transformation involving derivative terms. Our approach is to apply the metho…
Possible Explanation of the Geograv Detector Signal during the Explosion of SN 1987A in Modified Gravity Models
Yu. N. Eroshenko, E. O. Babichev, V. I. Dokuchaev +1
A change in gravity law in some regimes is predicted in the modified gravity models that are actively discussed at present. In this paper, we consider a possibility that the signal…
Reconciling spontaneous scalarization with cosmology
Timothy Anson, Eugeny Babichev, Sabir Ramazanov
We discuss the Damour--Esposito-Farèse model of gravity, which predicts the spontaneous scalarization of neutron stars in a certain range of parameter space. In the cosmological se…
Cosmological instability of scalar-Gauss-Bonnet theories exhibiting scalarization
Timothy Anson, Eugeny Babichev, Christos Charmousis +1
In a subclass of scalar-tensor theories, it has been shown that standard general relativity solutions of neutron stars and black holes with trivial scalar field profiles are unstab…
