We show that the combination of the roton instability and quantum stabilization leads under proper conditions to a novel regime that presents supersolid properties, due to the coexistence of stripe modulation and phase coherence. In a combined experimental and theoretical analysis, we determine the parameter regime for the formation of coherent stripes, whose lifetime of a few tens of millisec","authors_text":"Andrea Fioretti, Carlo Gabbanini, Eleonora Lucioni, Francesca Fam\\`a, Giovanni Modugno, Jacopo Catani, Luca Tanzi, Luis Santos, Russell N.
