High Energy Theory Seminar
Fluctuations and Viscosity
Sound waves with long-distance propagation are both a consequence of
hydrodynamics, and a danger to hydrodynamics' very existence, as they
violate the assumption of local equilibration. In the talk, I will
discuss what the thermally excited sound and shear waves do to
viscosity. In 2+1 dimensions, the shear viscosity and the charge
conductivity cease being independent transport coefficients. In 3+1
dimensions, the fluctuations render second-order hydrodynamics invalid.
