| Zusammenfassung: | Phys. Rev. D 92, 105011 (2015) Shear viscosity of the classical $\Phi^4$ theory is measured using classical
microcanonical simulation. To calculate the Kubo formula, we measure the
energy-momentum tensor correlation function, and apply the Green-Kubo relation.
Being a classical theory, the results depend on the cutoff which should be
chosen in the range of the temperature. Comparison with experimentally
accessible systems is also performed. |
