Transport coefficients in non-quasiparticle systems
Transport coefficients, in particular the shear viscosity to entropy density ratio are studied in systems where the small-width quasiparticle assumption is not valid. It is found that η/s has no universal lower bound, the minimal value depends on the system and the temperature, and can be even zero....
