Transport coefficients in non-quasiparticle systems

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

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 ν/s has no universal lower bound, the minimal value depends on the system and the temperature, and can be even zero. We construct models where the 1/4π conjectured bound is violated.
