Quadratic curvature corrections to stringy effective actions and the absence of de Sitter vacua
Francesc Cunillera, William T. Emond, Antoine Lehébel +1
We investigate the combined effect of fluxes and higher-order curvature corrections, in the form of the Gauss-Bonnet term, on the existence of de Sitter vacua in a heterotic string…
Neutron star scalarization with Gauss-Bonnet and Ricci scalar couplings
Giulia Ventagli, Georgios Antoniou, Antoine Lehébel +1
Spontaneous scalarization of neutron stars has been extensively studied in the Damour and Esposito-Farèse model, in which a scalar field couples to the Ricci scalar or, equivalentl…
Black hole scalarization with Gauss-Bonnet and Ricci scalar couplings
Georgios Antoniou, Antoine Lehébel, Giulia Ventagli +1
Spontaneous scalarization is a gravitational phenomenon in which deviations from general relativity arise once a certain threshold in curvature is exceeded, while being entirely ab…
