Current correlators and AdS/CFT away from the conformal point
A. Brandhuber, K. Sfetsos
Using the AdS/CFT correspondence we study vacua of N=4 SYM for which part of the gauge symmetry is broken by expectation values of scalar fields. A specific subclass of such vacua…
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…
Wilson loops from multicentre and rotating branes, mass gaps and phase structure in gauge theories
A. Brandhuber, K. Sfetsos
Within the AdS/CFT correspondence we use multicentre D3-brane metrics to investigate Wilson loops and compute the associated heavy quark-antiquark potentials for the strongly coupl…
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-…
On T-Duality and Supersymmetry
Konstadinos Sfetsos
The interplay between T-duality and supersymmetry in string theory is explored. It is shown that T-duality is always compatible with supersymmetry and simply changes a local realiz…
