Phenomenological model of decaying Bose polarons
Ragheed Alhyder, Georg M. Bruun, Thomas Pohl +2
Cold atom experiments show that a mobile impurity particle immersed in a Bose-Einstein condensate forms a well-defined quasiparticle (Bose polaron) for weak to moderate impurity-bo…

Green's function approach to interacting lattice polaritons and optical nonlinearities in subwavelength arrays of quantum emitters
Simon Panyella Pedersen, Georg M. Bruun, Thomas Pohl
Sub-wavelength arrays of quantum emitters offer an efficient free-space approach to coherent light-matter interfacing, using ultracold atoms or two-dimensional solid-state quantum…
