dreibein

Noun

dreibein (plural dreibeins)

1. Trihedron.
   • Three orthonormal vectors #92;hat#123;l#125;, #92;hat#123;e#125;#123;(1)#125; and #92;hat#123;e#125;#123;(2)#125; form the dreiben - a local physical coordinate frame of the A-phase vacuum.1992, G. E. Volovik, Exotic Properties of Superfluid 3He, page 21
   • 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...2016, Alfredo Guevara, Pablo Pais, Jorge Zanelli, “Dynamical Contents of Unconventional Supersymmetry”, in arXiv
