Random anisotropy disorder in superfluid 3He-A in aerogel

  • G. E. Volovik
Article

Abstract

Anisotropic superfluid 3He-A in aerogel provides an interesting example of a system with continuous symmetry in the presence of random anisotropy disorder. Recent NMR experiments allow us to discuss two regimes of the orientational disorder that have different NMR properties. One of them, the (c) state, is identified as the pure Larkin-Imry-Ma state. The structure of another state, the (f) state, is not very clear: probably, it is the Larkin-Imry-Ma state contaminated by the network of the topological defects pinned by the aerogel.
