Exact relations between the conductivities and their connection to the chemical composition of QCD matter

Jan A. Fotakis, Jakob E. Lohr, Carsten Greiner

We present exact relations between the diffusion coefficients or conductivities, ${\kappa }_{q{q}^{\prime }}/T={\sigma }_{q{q}^{\prime }}$, of strongly-interacting matter. We show that once the diagonal entries are k…
