Bounds on transport from hydrodynamic stability
It was recently shown that the dispersion relations describing singularities of retarded two-point functions in causal quantum field theories always satisfy the fundamental inequality Imω≤|Imk|, and that several rigorous bounds on transport coefficients follow directly from such inequality. Here, we...
