String junctions in curved backgrounds, their stability and dyon interactions in SYM
Konstadinos Sfetsos, Konstadinos Siampos
We provide a systematic construction of string junctions in curved backgrounds which are relevant in computing, within the gauge/gravity correspondence, the interaction energy of h…
Stability of string configurations dual to quarkonium states in AdS/CFT
Spyros D. Avramis, Konstadinos Sfetsos, Konstadinos Siampos
We extend our earlier work, regarding the perturbative stability of string configurations used for computing the interaction potential of heavy quarks within the gauge/gravity corr…
Complex marginal deformations of D3-brane geometries, their Penrose limits and giant gravitons
Spyros D. Avramis, Konstadinos Sfetsos, Dimitrios Zoakos
We apply the Lunin--Maldacena construction of gravity duals to beta-deformed gauge theories to a class of Type IIB backgrounds with U(1)^3 global symmetry, which include the multic…
Stability of strings dual to flux tubes between static quarks in N=4 SYM
Spyros D. Avramis, Konstadinos Sfetsos, Konstadinos Siampos
Computing heavy quark-antiquark potentials within the AdS/CFT correspondence often leads to behaviors that differ from what one expects on general physical grounds and field-theory…
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…
