Quantum geometry and flat band Bose-Einstein condensation
Aleksi Julku, Georg M. Bruun, Päivi Törmä
We study the properties of a weakly interacting Bose-Einstein condensate (BEC) in a flat band lattice system by using multiband Bogoliubov theory, and discover fundamental connecti…

Nonlinear optical response of resonantly driven polaron-polaritons
Aleksi Julku, Miguel. A. Bastarrachea-Magnani, Arturo Camacho-Guardian +1
Exciton polaritons in two-dimensional semiconductors inside microcavities are powerful platforms to explore hybrid light-matter quantum systems. Here, we study a macroscopic cohere…
