QCD from the lattice.

Abstract
We present a lattice QCD calculation of the charge diffusion coefficient, the
electrical conductivity and various susceptibilities of conserved charges, for a range of
temperatures below and above the deconfinement crossover. The calculations include the
contributions from up, down and strange quarks. We find that the diffusion coefficient is
of the order of 1/(2πT) and has a dip around the crossover temperature. Our results are
obtained with lattice simulations containing 2+1 dynamical flavours on anisotropic lattices.
The Maximum Entropy Method is used to construct spectral functions from correlators of
the conserved vector current.
