We study the effective geometry felt by the fluctuations of open strings living on the worldvolume of probe D-branes in the presence of background electromagnetic fields. This is captured by an effective action consisting of a Maxwell term and a topological term, with the role of the metric played by the open string metric. Studying generalized Eddington-Finkelstein coordinates for stationary but non-static manifolds, we consider an open string membrane paradigm to obtain a generic formula for…

Probe branes thermalization in external electric and magnetic fields
Abstract We study thermalization on rotating probe branes in AdS 5 × S 5 background in the presence of constant external electric and magnetic fields. In the AdS/CFT framework this corresponds to
