Fig. 4: Normalized fluctuation contribution vs reduced temperature.
From: Observation of suppressed viscosity in the normal state of 3He due to superfluid fluctuations
a The measured excess Q (see Fig. 3) of the quartz fork at various pressures, normalized to Qc (see Fig. 3c) plotted against the square root of reduced temperature. This plot shows that the contribution to Q of the fluctuation component increases faster than the increase of Qc with pressure. b δQ normalized to δQc (see Eqs. (3), (4)). The dashed line shows the expected temperature-dependent fit to the fluctuation component of viscosity in Eq. (1) (see ref. 1). The shaded gray region represents the 1σ range in the curve fit based upon the error in the fit parameters.
