Conical singularities and the Vainshtein screening in full GLPV theories
Ryotaro Kase, Shinji Tsujikawa, Antonio De Felice
In Gleyzes-Langlois-Piazza-Vernizzi (GLPV) theories, it is known that the conical singularity arises at the center of a spherically symmetric body () in the case where the par…
Cosmology with a successful Vainshtein screening in theories beyond Horndeski
Ryotaro Kase, Shinji Tsujikawa, Antonio De Felice
We propose a dark energy model where a scalar field has nonlinear self-interactions in the presence of a dilatonic coupling with the Ricci scalar. This belongs to a sub-class o…
Existence and disappearance of conical singularities in Gleyzes-Langlois-Piazza-Vernizzi theories
Antonio De Felice, Ryotaro Kase, Shinji Tsujikawa
In a class of Gleyzes-Langlois-Piazza-Vernizzi (GLPV) theories, we derive both vacuum and interior Schwarzschild solutions under the condition that the derivatives of a scalar fiel…
