Crossing Over from Attractive to Repulsive Interactions in a Tunneling Bosonic Josephson Junction

G. Spagnolli, G. Semeghini, L. Masi +9

We explore the interplay between tunneling and interatomic interactions in the dynamics of a bosonic Josephson junction. We tune the scattering length of an atomic ${}^{39}$K Bose-Ei…
