Shock waves in strongly coupled plasmas II
Sergei Khlebnikov, Martin Kruczenski, Georgios Michalogiorgakis
In a recent paper we have analyzed the AdS/CFT duals to shock waves propagating in the N=4 plasma. Here we study further properties of the system. In the gravity description we con…
Improved Holographic QCD
Umut Gürsoy, Elias Kiritsis, Liuba Mazzanti +2
We provide a review to holographic models based on Einstein-dilaton gravity with a potential in 5 dimensions. Such theories, for a judicious choice of potential are very close to t…
Shock waves in strongly coupled plasmas
Sergei Khlebnikov, Martin Kruczenski, Georgios Michalogiorgakis
Shock waves are supersonic disturbances propagating in a fluid and giving rise to dissipation and drag. Weak shocks, i.e., those of small amplitude, can be well described within th…
Thermal Transport and Drag Force in Improved Holographic QCD
Umut Gürsoy, Elias Kiritsis, Georgios Michalogiorgakis +1
We calculate the bulk viscosity, drag force and jet quenching parameter in Improved Holographic QCD. We find that the bulk viscosity rises near the phase transition but does not ex…
Entanglement entropy of two dimensional systems and holography
Georgios Michalogiorgakis
In this note a new method for computing the entanglement entropy of a CFT holographically is explored. It consists of finding a bulk background with a boundary metric that has the…
Low-lying gravitational modes in the scalar sector of the global AdS_4 black hole
Georgios Michalogiorgakis, Silviu S. Pufu
We compute the quasinormal frequencies corresponding to the scalar sector of gravitational perturbations in the four-dimensional AdS-Schwarzschild black hole by using the master fi…
