Langevin diffusion of heavy quarks in non-conformal holographic backgrounds

Understand

The Langevin diffusion process of a relativistic heavy quark in a non-conformal holographic setup is discussed.

• The bulk geometry is a general, five-dimensional asymptotically AdS black hole.
• The heavy quark is described by a trailing string attached to a flavor brane, moving at constant velocity.
• From the equations describing linearized fluctuations of the string world-sheet, the correlation functions defining a generalized Langevin process are constructed via the AdS/CFT prescription.
