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…
Instabilities of D-brane Bound States and Their Related Theories
Joshua J. Friess, Steven S. Gubser
We investigate the Gregory-Laflamme instability for bound states of branes in type II string theory and in M-theory. We examine systems with two different constituent branes: for i…
Hawking Effect in 2-D String Theory
Joshua J. Friess, Herman Verlinde
We use the matrix model to study the final state resulting from a coherent high energy pulse in 2-d string theory at large string coupling. We show that the outgoing signal produce…
