Topological Bogoliubov Quasiparticles from Bose-Einstein Condensate in a Flat Band System

A team of researchers led by ICREA Prof. at ICFO Maciej Lewenstein, who is also the Dynamite project coordinator, reports in Physical Review Letters on the stability of Bose Einstein Condensates, where Bogoliubov excitation modes have non-trivial topological properties.
