On the integrability of spherical gravitational waves in vacuum
Ioannis Bakas
The general class of Robinson-Trautman metrics that describe gravitational radiation in the exterior of bounded sources in four space-time dimensions is shown to admit zero curvatu…
Supersymmetry and finite-temperature strings
I. Bakas, A. Bilal, J. -P. Derendinger +1
We describe finite temperature N=4 superstrings in D=5 by an effective four-dimensional supergravity of the thermal winding modes that can become tachyonic and trigger the instabil…
Riemann surfaces and Schrodinger potentials of gauged supergravity
I. Bakas, A. Brandhuber, K. Sfetsos
Supersymmetric domain-wall solutions of maximal gauged supergravity are classified in 4, 5 and 7 dimensions in the presence of non-trivial scalar fields taking values in the coset…
2-D gravisolitons in string theory
I. Bakas
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…
String effects and field theory puzzles with supersymmetry
I. Bakas, K. Sfetsos
We investigate field theory puzzles occuring in the interplay between supersymmetry and duality in the presense of rotational isometries (also known as non-triholomorphic in hyper-…
String Dualities and the Geroch Group
Ioannis Bakas
We examine the properties and symmetries of the lowest order effective theory of 4-dim string backgrounds with axion and dilaton fields and zero cosmological constant. The dimensio…
