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…

Tweezer interferometry with NOON states
Yehoshua Winsten, Doron Cohen, Yoav Sagi
Atomic interferometers measure phase differences along paths with exceptional precision. Tweezer interferometry represents a novel approach for this measurement by guiding particle…
