Dynamics of He3 in one dimension in the Luttinger liquid limit

Abstract

NMR techniques have been used to investigate the dynamics of highly degenerate 3 He confined to the interior of 4 He plated nanotubes of MCM-41. The 3 He line density was 0.93 ± 0.10 nm −1 , corresponding to a Fermi degeneracy temperature of TF ≈ 0.1 K. Experiments conducted down to 10 mK reveal a linear temperature dependence of the nuclear spin-lattice relaxation for T < TF , following a peak at 2TF , which are hallmarks of Luttinger liquid physics .
