   • 1992, G. E. Volovik, Exotic Properties of Superfluid 3He, page 21:

     Three orthonormal vectors ${\displaystyle {\hat {l}}}$, ${\displaystyle {\hat {e}}^{(1)}}$ and ${\displaystyle {\hat {e}}^{(2)}}$ form the dreiben - a local physical coordinate frame of the A-phase vacuum.

   • 2016, Alfredo Guevara, Pablo Pais, Jorge Zanelli, “Dynamical Contents of Unconventional Supersymmetry”, in arXiv‎^[1]:

     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.
