Stress tensor of static dipoles in strongly coupled N=4 gauge theory
Abstract
In the context of the AdS/CFT correspondence we calculate the induced stress tensor of static dipoles (electricelectric and electricmagnetic) in a strongly coupled N=4 SYM gauge theory, by solving the linearized Einstein equation with Maldecena string as a source. Analytic expressions are given for the farfield and a nearfield close to one charge, and compared to what one has in weak coupling. The result can be compared to lattice results for QCDlike theories in a deconfined but strongly coupled regime.
