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…
Anomaly-Free Supergravities in Six Dimensions
Spyros D. Avramis
This thesis reviews minimal N=2 chiral supergravities coupled to matter in six dimensions with emphasis on anomaly cancellation. In general, six-dimensional chiral supergravities s…
On the velocity and chemical-potential dependence of the heavy-quark interaction in N=4 SYM plasmas
Spyros D. Avramis, Konstadinos Sfetsos, Dimitrios Zoakos
We consider the interaction of a heavy quark-antiquark pair moving in N=4 SYM plasma in the presence of non-vanishing chemical potentials. Of particular importance is the maximal l…
Supergravity and the jet quenching parameter in the presence of R-charge densities
Spyros D. Avramis, Konstadinos Sfetsos
Following a recent proposal, we employ the AdS/CFT correspondence to compute the jet quenching parameter for N=4 Yang-Mills theory at nonzero R-charge densities. Using as dual supe…
