A Ratio of the Shear Viscosity to the Density of Entropy for Helium
Keywords:Helium, ratio of the shear viscosity to the density of entropy, Kovtun–Son–Starinets inequality
We have studied the ratio (n/s) of the shear viscosity n to the density of entropy s for helium as a function of the temperature and have established that the minimal value, (n/s)min, satisfies the Kovtun–Son–Starinets inequality, (n/s)min ≥ (h/4пkB).
