Charged polarons and molecules in a Bose-Einstein Condensate
Esben Rohan Christensen, Arturo Camacho-Guardian, Georg M. Bruun
We investigate the properties a mobile ion immersed in a Bose-Einstein condensate (BEC) using different theoretical approaches. A coherent state variational ansatz predicts that th…
Attractive and repulsive exciton-polariton interactions mediated by an electron gas
M. A. Bastarrachea-Magnani, A. Camacho-Guardian, G. M. Bruun
Realising strong photon-photon interactions in a solid-state setting is a major goal with far reaching potential for optoelectronic applications. Using Landau's quasiparticle frame…
Non-equilibrium quantum dynamics and formation of the Bose polaron
Magnus G. Skou, Thomas G. Skov, Nils B. Jørgensen +5
Advancing our understanding of non-equilibrium phenomena in quantum many-body systems remains among the greatest challenges in physics. Here, we report on the experimental observat…
Mediated interactions and photon bound states in an exciton-polariton mixture
A. Camacho-Guardian, M. Bastarrachea-Magnani, G. M. Bruun
The quest to realise strongly interacting photons remains an outstanding challenge both for fundamental science and for applications. Here, we explore mediated photon-photon intera…
Superfluid flow of polaron polaritons above Landau's critical velocity
K. Knakkergaard Nielsen, A. Camacho-Guardian, G. M. Bruun +1
We develop a theory for the interaction of light with superfluid optical media, describing the motion of quantum impurities that are created and dragged through the liquid by propa…
