" Triplet pairing due to spin-orbit-assisted electron-phonon coupling "


	Abstract


We propose a microscopic mechanism for triplet pairing due to 
spin-orbit-assisted electron interaction with optical phonons in a 
crystal with a complex unit cell.  Using two examples of electrons with 
symmetric Fermi surfaces in crystals with either a cubic or a layered 
square lattice, we show that spin-orbit-assisted electron-phonon 
coupling can, indeed, generate triplet pairing and that, in each case, 
it predetermines the tensor structure of a p-wave order parameter.
