SUMMARY: Stefano Chesi: Spin polarized transmission of holes in quantum\npo
 int-contacts with strong spin-orbit coupling
CLASS:PUBLIC
DESCRIPTION:Summary \n\nABSTRACT\n\nEvidence is presented for the finite wa
 ve vector crossing of the two\nlowest one-dimensional spin-split subbands 
 in quantum point contacts\nfabricated from two-dimensional hole gases with
  strong spin-orbit\ninteraction. This phenomenon offers an elegant explana
 tion for the\nanomalous sign of the spin polarization filtered by a point 
 contact\,\nas observed in magnetic focusing experiments. Anticrossing is\n
 introduced by a magnetic field parallel to the channel or an\nasymmetric p
 otential transverse to it.\n
