Effect of random anisotropy on NMR frequency shift in the polar phase of the superfluid 3He

Published 15 Jan 2019 in cond-mat.dis-nn | (1901.05025v2)

Abstract: The orbital anisotropy induced in the superfluid 3He by nematic aerogel is, generally speaking, spatially non-uniform. This anisotropy in its turn induces spatial fluctuations of the order parameter. It is shown here that for the polar phase these fluctuations decrease the overall amplitude of the order parameter and the value of the frequency shift of the transverse NMR. Different contributions to this effect are discussed and estimated. Their temperature dependencies are discssed as well.
