From few to many bosons inside the unitary window: a transition between universal to non-universal behavior
A. Kievsky, A. Polls, B. Juliá-Díaz +2
Universal behaviour in few-bosons systems close to the unitary limit, where two bosons become unbound, has been intensively investigated in recent years both experimentally and the…

Fast generation of spin-squeezed states in bosonic Josephson junctions
B. Juliá-Díaz, E. Torrontegui, J. Martorell +2
We describe methods for fast production of highly coherent-spin-squeezed many-body states in bosonic Josephson junctions (BJJs). We start from the known mapping of the two-site Bos…
