We compute the energy density radiated by a quark undergoing circular motion in strongly coupled N = 4 supersymmetric Yang-Mills plasma. If it were in vacuum, this quark would radiate a beam of strongly coupled radiation whose angular distribution has been characterized and is very similar to that of synchrotron radiation produced by an electron in circular motion in electrodynamics. Here, we watch this beam of gluons getting quenched by the strongly coupled plasma. We find that a beam of gluons of momenta ∼ q πT is attenuated rapidly, over a distance ∼ q 1/3 (πT ) −4/3 in a plasma with temperature T . As the beam propagates through the plasma at the speed of light, it sheds trailing sound waves with momenta πT . Presumably these sound waves would thermalize in the plasma if they were not hit soon after their production by the next pulse of gluons from the lighthouse-like rotating quark. At larger and larger q, the trailing sound wave becomes less and less prominent. The outward going beam of gluon radiation itself shows no tendency to spread in angle or to shift toward larger wavelengths, even as it is completely attenuated. In this regard, the behavior of the beam of gluons that we analyze is reminiscent of the behavior of jets produced in heavy ion collisions at the LHC that lose a significant fraction of their energy without appreciable change in their angular distribution or their momentum distribution as they plow through the strongly coupled quark-gluon plasma produced in these collisions.

Abstract:We study the time evolution of cMERA (continuous MERA) under quantum quenches in free field theories. We calculate the corresponding holographic metric using the proposal in arXiv:1208.3469 and confirm that it qualitatively agrees with its gravity dual given by a half of the AdS black hole spacetime, argued by Hartman and Maldacena in arXiv:1303.1080. By doubling the cMERA for the quantum quench, we give an explicit construction of finite temperature cMERA. We also study cMERA in the presence of chemical potential and show that there is an enhancement of metric in the infrared region corresponding to the Fermi energy.

Non-Relativistic Holography from Hořava Gravity Stefan Janiszewski Chair of the Supervisory Committee:Professor Andreas Karch Department of PhysicsHolography is a powerful theoretical duality that relates quantum gravitational theories to non-gravitational theories in one less dimension. The most explored example of this tool is the correspondence between general relativity on five dimensional Anti-deSitter space and a four dimensional supersymmetric Yang-Mills theory. This case is extremely useful as the strong coupling regime of the Yang-Mills theory is solved by weakly coupled gravity.Another interesting class of strongly coupled field theories are those of a nonrelativistic nature that arise in condensed matter systems. Herein, motivated by the generic symmetry structure of these theories, a non-relativistic version of holography is proposed using an alternate theory of gravity, Hořava gravity. Justifications of this proposal are thoroughly discussed. Various checks of the duality, such as correlation functions and black hole thermodynamics are presented. This new holographic correspondence provides a crucial tool to tackle strongly coupled problems in condensed matter systems. On the other hand, Hořava gravity, thought to be a UV complete theory of quantum gravity, will allow holography to move away from the strong coupling, large number of colors limit that has restricted traditional AdS/CFT.
