Mass flux characteristics in solid 4He for T>100 mK: evidence for bosonic Luttinger-liquid behavior
1Laboratory for Low Temperature Physics, Department of Physics, University of Massachusetts, Amherst, Massachusetts 01003, USA.
Abstract:
At a pressure of ~25.7 bar, the flux F carried by solid (4)He for T>100 mK depends on the net chemical potential difference between two reservoirs in series with the solid, Δμ, and obeys F~(Δμ)(b), where b≈0.3 is independent of temperature. At fixed Δμ the temperature dependence of the flux F can be adequately represented by F~-ln(T/τ), τ≈0.6 K, for 0.1≤T≤0.5 K. A single function F=F(0)(Δμ)(b)ln(T/τ) fits all of the available data sets in the range 25.6-25.8 bar reasonably well. We suggest that the mass flux in solid (4)He for T>100 mK may have a Luttinger liquidlike behavior in this bosonic system.
