We use soliton techniques of the two-dimensional reduced {beta}-function equations to obtain nontrivial string backgrounds from flat space. These solutions are characterized by two integers ({ital n},{ital m}) referring to the soliton numbers of the metric and axion-dilaton sectors, respectively. We show that the Nappi-Witten universe associated with the SL(2){times}SU(2)/SO(1,1){times}U(1) CFT coset arises as a (1,1) soliton in this fashion for certain values of the moduli parameters, while…
All extremal instantons in Einstein-Maxwell-dilaton-axion theory
• Mathematics, Physics
• 2011
We construct explicitly all extremal instanton solutions to $\mathcal{N}=4$, $D=4$ supergravity truncated to one vector field (Einstein-Maxwell-dilaton-axion theory). These correspond to null
On integrable models from pp-wave string backgrounds
• Physics
• 2002
We construct solutions of type-IIB supergravity with non-trivial Ramond- Ramond 5-form in ten dimensions by replacing the transverse ∞at space of pp-wave back- grounds with exact N = (4;4) c = 4
2-D gravisolitons in string theory
Several gravitational string backgrounds can be interpreted as 2-dim soliton solutions of reduced axion-dilaton gravity. They include black-hole and worm-hole solutions as well as cosmological models
Ehlers-Harrison transformations and black holes in dilaton-axion gravity with multiple vector fields
• Physics
• 1997
Dilaton-axion gravity with $p U(1)$ vector fields is studied on space-times admitting a timelike Killing vector field. Three-dimensional sigma-model is derived in terms of K\"ahler geometry, and
Axion-fermion Coupling and Dyon Charge as Physical Signatures of a Space-time Inner Symmetry
In this paper we intend to complement the identification given in Kuerten & FernandesSilva [1] (Mod. Phys. Lett. A. Vol. 33, No. 16) which relates the axion to a metric spinor phase by means of

Several gravitational string backgrounds can be interpreted as 2-dim soliton solutions of reduced axion-dilaton gravity. They include black-hole and wormhole solutions as well as cosmological models
Solitons via Lie-Bäcklund transformation for 5D low-energy string theory
• Physics
• 2009
We apply a non-linear matrix transformation of Lie-Bäcklund type on a seed soliton configuration in order to obtain a new solitonic solution in the framework of the 5D low-energy effective field
