Transition from Propagating Polariton Solitons to a Standing Wave Condensate Induced by Interactions (American Physical Society (APS), 2018-04-19)We explore phase transitions of polariton wave packets, first, to a soliton and then to a standing wave polariton condensate in a multimode microwire system, mediated by nonlinear polariton interactions. At low excitation density, we observe ballistic ... -
(MDPI, 2021-11-02)Salmon is the most consumed farmed seafood in the EU and there is no indication that demand will abate. Yet salmon aquaculture’s environmental impacts are significant, and its future is likely to be shaped by demands of increased but at the same time ...

(Scandinavian University Press / Universitetsforlaget AS, 2019-11-11)Sleep has been found to be an important factor in adolescents’ mental and physical health. The aim of the present study was to examine trends in sleep difficulty (i.e., difficulty falling asleep more often than once a week) in the Nordic countries among ...

(Public Library of Science (PLoS), 2018-08-22)Background Tobacco consumption is the largest avoidable health risk. Understanding changes of smoking over time and across populations is crucial to implementing health policies. We evaluated trends in smoking initiation between 1970 and 2009 in random ...
