Supefluidity of flat band Bose-Einstein condensates revisited

Aleksi Julku, Grazia Salerno, Päivi Törmä

We consider the superfluid weight, speed of sound and excitation fraction of a flat band Bose-Einstein condensate (BEC) within multiband Bogoliubov theory. The superfluid weight is…

Loss-driven topological transitions in lasing

Grazia Salerno, Rebecca Heilmann, Kristian Arjas +3

We experimentally observe lasing in a hexamer plasmonic lattice and find that when tuning the scale of the unit cell, the polarization winding of the emission changes. By a theoret…
