Abstract:
We analysis physical observables of heavy quarks in gravity models describing
strongly coupled non-conformal plasmas with anisotropy via the gauge/gravity
duality. The focus lies on the binding energy of static quark-antiquark $(q\bar
q$-)pairs, the maximum distance (screening distance) of a bound $q\bar q$-pair
and the drag force on uniformly moving quarks in the hot plasma. In order to
discover universal behavior in the observables, the computations are worked out
in a two parameter deformation of pure gravity in $AdS_5$ spacetime with a
black brane which is assumed to be dual to a respective two parameter
deformation of $\mathcal{N}$=\,4 supersymmetric Yang-Mills (SYM) theory at
temperature $T$. The deformation is designed to break isotropy and conformal
symmetry and is a solution to equations of motion of a gravity action.
