Entropy production in collisions of gravitational shock waves and of heavy ions
Steven S. Gubser, Silviu S. Pufu, Amos Yarom
We calculate the area of a marginally trapped surface formed by a head-on collision of gravitational shock waves in AdS_D. We use this to obtain a lower bound on the entropy produc…
Thermodynamics and bulk viscosity of approximate black hole duals to finite temperature quantum chromodynamics
Steven S. Gubser, Abhinav Nellore, Silviu S. Pufu +1
We consider classes of translationally invariant black hole solutions whose equations of state closely resemble that of QCD at zero chemical potential. We use these backgrounds to…
Gluon energy loss in the gauge-string duality
Steven S. Gubser, Daniel R. Gulotta, Silviu S. Pufu +1
We estimate the stopping length of an energetic gluon in a thermal plasma of strongly coupled N=4 super-Yang-Mills theory by representing the gluon as a doubled string rising up ou…
Shock waves from heavy-quark mesons in AdS/CFT
Steven S. Gubser, Silviu S. Pufu, Amos Yarom
We calculate the far-field stress-energy tensor of a quark gluon plasma due to a heavy-quark meson moving through it, using a semi-classical description in string theory of the mes…
Sonic booms and diffusion wakes generated by a heavy quark in thermal AdS/CFT
Steven S. Gubser, Silviu S. Pufu, Amos Yarom
We evaluate the Poynting vector generated by a heavy quark moving through a thermal state of N=4 gauge theory using AdS/CFT. A significant diffusion wake is observed as well as a M…
Master field treatment of metric perturbations sourced by the trailing string
Steven S. Gubser, Silviu S. Pufu
We present decoupled, separable forms of the linearized Einstein equations sourced by a string trailing behind an external quark moving through a thermal state of N=4 super-Yang-Mi…
