Abstract

We report an experimental observation and theoretical study of a new non dissipative nonlocal Josephson current which is carried by an Andreev bound state ABS connecting three superconducting terminals set at nonzero voltages 1 Sensitive low frequency cross correlation measurements of current fluctuations prove the origin of the effect and point to its non local characteristics 2 In addition a rich subharmonic gap structure which arises from non local multiple Andreev reflections processes was observed for the first time 3 References 1 A Freyn et al Phys Rev Lett 106 257005 2011 2 R M lin et al arXiv:1511 08436 cond mat mes hall 2010 3 M Houzet et al Phys Rev B 82 060517 R 2010
