Universality in strongly interacting bosonic clusters
L. Madeira, F. Pederiva, U. van Kolck
We develop an effective field theory (EFT) for strongly interacting bosonic clusters, using He as a paradigmatic example of universality in systems with large scattering length…

Spectroscopy of collective modes in a Bose-Einstein condensate: From single to double excitation periods
Leandro A. Machado, Lucas Madeira, Mônica A. Caracanhas +1
Collective modes are coherent excitations in Bose-Einstein condensates (BECs), and their study provides insight into the macroscopic quantum phenomena that govern these systems. Co…
