Josephson effects in one-dimensional supersolids

Kunimi, Masaya*; Nagai, Yuki ; Kato, Yusuke*

We demonstrate that superflow past an obstacle is possible in a solid phase in the one-dimensional Gross-Pitaevskii equation with a finite-range two-body interaction. The phenomenon we find is analogous to the DC Josephson effect in superconductors. We show the phase diagram in the plane of the current and the interaction strength.
