Description

We study dynamical properties of one-dimensional supersolids in the framework of the Gross-Pitaevskii equation with a finite-range two-body interaction in the presence of an obstacle. Above a critical velocity, superfluidity breaks down and solitons are emitted periodically as in the case of superfluids. However, near the critical velocity, the period of soliton emissions obeys a scaling law which is different from that in superfluids.
