- 1992, G. E. Volovik, Exotic Properties of Superfluid 3He, page 21:
  Three orthonormal vectors ${\hat {l}}$ , ${\hat {e}}^{(1)}$ and ${\hat {e}}^{(2)}$ form the dreiben - a local physical coordinate frame of the A-phase vacuum.

  This is shown for the following canonical sectors: i) a conformally invariant generic description where the spinor field and the dreibein are locally rescaled; ii) a specific configuration for the Dirac fermion consistent with its spin, where Weyl symmetry is exchanged by time reparametrizations; iii) the vacuum sector 1, which is of interest for perturbation theory.
