Spin and Charge Josephson effects between non-uniform superconductors with coexisting helimagnetic order

Ilya Eremin, Flavio S. Nogueira, Rene-Jean Tarento

We consider the spin and charge Josephson current between two non-uniform Fulde-Ferrel-Larkin-Ovchinnikov superconductors with helimagnetic order. We demonstrate that the presence…
