Non-extremal instantons and wormholes in string theory
E. Bergshoeff, A. Collinucci, U. Gran +2
We construct the most general non-extremal spherically symmetric instanton solution of a gravity-dilaton-axion system with symmetry, for arbitrary euclidean spacetime dim…

Non-extremal D-instantons
E. Bergshoeff, A. Collinucci, U. Gran +2
We construct the most general non-extremal deformation of the D-instanton solution with maximal rotational symmetry. The general non-supersymmetric solution carries electric charge…

Transient Quintessence from Group Manifold Reductions or how all roads lead to Rome
Eric Bergshoeff, Andres Collinucci, Ulf Gran +2
We investigate the accelerating phases of cosmologies supported by a metric, scalars and a single exponential scalar potential. The different solutions can be represented by trajec…
