Mesoscopic superfluid to superconductor transition
Yehoshua Winsten, Doron Cohen
Spectrum tomography for the energy () of a ring-shaped Bose-Hubbard circuit is illustrated. There is an inter-particle interaction that controls superfluidity (SF) and the t…

Quantum tomography of the superfluid-insulator transition for a mesoscopic atomtronic ring
Yehoshua Winsten, Doron Cohen
We provide a phase-space perspective for the analysis of the superfluid-insulator transition for finite-size Bose-Hubbard circuits. We explore how the eigenstates parametrically ev…
