  LPEM day

  The LPEM day took place on 15 June 2023. It was the opportunity to (re-)discover what the other teams are doing, who the newcomers are, and to discuss science and lab life over a delicious (...)

  Spin-Orbit induced phase-shift in Bi2Se3 Josephson junctions

  The transmission of Cooper pairs between two weakly coupled superconductors produces a superfluid current and a phase difference; the celebrated Josephson effect. Because of time-reversal and (...)
