Open AccessEinstein–Cartan pseudoscalaron inflation
We study a class of early universe cosmological models based on Einstein–Cartan gravity and including a higher derivative term corresponding to a power of the Holst scalar curvature. The resulting effective ac...

Open AccessMulticenter solutions in Eddington-inspired Born–Infeld gravity
We find multicenter (Majumdar–Papapetrou type) solutions of Eddington-inspired Born–Infeld gravity coupled to electromagnetic fields governed by a Born–Infeld-like Lagrangian. We construct the general solution...

Open AccessRicci-Based Gravity theories and their impact on Maxwell and nonlinear electromagnetic models
We extend the correspondence between metric-affine Ricci-Based Gravity the- ories and General Relativity (GR) to the case in which the matter sector is represented by linear and nonlinear electromagnetic field...

Open AccessMap** nonlinear gravity into General Relativity with nonlinear electrodynamics
We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into general relativity (GR) coupled to another non...

Open AccessDualities near the horizon
In 4-dimensional supergravity theories, covariant under symplectic electricmagnetic duality rotations, a significant role is played by the symplectic matrix ...

On the AdS/BCFT approach to quantum Hall systems
In this paper we study a simple gravity model dual to a 2 + 1-dimensional system with a boundary at finite charge density and temperature. In our naive AdS/BCF T extension of a well known AdS/CFT system a non-zer...
