Holographic spectral functions and diffusion constants for fundamental matter

Myers, Robert C., Starinets, Andrei O. and Thomson, Rowan M. (2007) Holographic spectral functions and diffusion constants for fundamental matter Journal of High Energy Physics, 11, (91), pp. 1-63. (doi:10.1088/1126-6708/2007/11/091).

The holographic dual of large-Nc super-Yang-Mills coupled to a small number of flavours of fundamental matter, Nf << Nc, is described by Nf probe D7-branes in the gravitational background of Nc black D3-branes. This system undergoes a first order phase transition characterised by the `melting' of the mesons. We study the high temperature phase in which the D7-branes extend through the black hole horizon. In this phase, we compute the spectral function for vector, scalar and pseudoscalar modes on the D7-brane probe. We also compute the diffusion constant for the flavour currents.
