Expanding plasmas and quasinormal modes of anti-de Sitter black holes
Joshua J. Friess, Steven S. Gubser, Georgios Michalogiorgakis +1
We compute the gravitational quasinormal modes of the global AdS_5-Schwarzschild solution. We show how to use the holographic dual of these modes to describe a thermal plasma of fi…
Stability of strings binding heavy-quark mesons
Joshua J. Friess, Steven S. Gubser, Georgios Michalogiorgakis +1
We investigate the stability against small deformations of strings dangling into AdS_5-Schwarzschild from a moving heavy quark-anti-quark pair. We speculate that emission of massiv…
The stress tensor of a quark moving through N=4 thermal plasma
Joshua J. Friess, Steven S. Gubser, Georgios Michalogiorgakis +1
We develop the linear equations that describe graviton perturbations of AdS_5-Schwarzschild generated by a string trailing behind an external quark moving with constant velocity. S…
Heterotic non-linear sigma models with anti-de Sitter target spaces
Georgios Michalogiorgakis, Steven S. Gubser
We calculate the beta function of non-linear sigma models with S^{D+1} and AdS_{D+1} target spaces in a 1/D expansion up to order 1/D^2 and to all orders in α'. This beta function…
Dissipation from a heavy quark moving through N=4 super-Yang-Mills plasma
Joshua J. Friess, Steven S. Gubser, Georgios Michalogiorgakis
Using AdS/CFT, we compute the Fourier space profile of <tr F^2> generated by a heavy quark moving through a thermal plasma of strongly coupled N=4 super-Yang-Mills theory. We find…
Non-linear sigma models with anti-de Sitter target spaces
Joshua J. Friess, Steven S. Gubser
We present evidence that there is a non-trivial fixed point for the AdS_{D+1} non-linear sigma model in two dimensions, without any matter fields or additional couplings beyond the…
