SUMMARY:Anomalous Josephson effect in spin-orbit coupled Nanowires\, R
 . G. Herb Condensed Matter Seminar\, Gabriele Campagnano\, University 
 of Naples "Federico II"
DESCRIPTION:Traditionally the Josephson current flowing between two su
 perconductors coupled by a normal region <br>
\n<br>
\n(either insulat
 ing or conducting) vanishes when the superconducting phase difference 
 between the two sides of the junction is zero.  This property can be s
 hown to be related to symmetries of the Bogoliubov-de Gennes equations
 \, the simultaneous presence of spin–orbit interaction and magnetic 
 field may break such symmetries.<br>
\n<br>
\nIn this seminar I will d
 iscuss the conditions required to have a finite anomalous Josephson cu
 rrent\, i.e. a supercurrent flowing when the phase difference is zero.
  In particular\, I will describe how this phenomenon is related to the
  band structure and to the geometrical realization of the normal regio
 n.
