Polaritons in an electron gas -- quasiparticles and Landau effective interactions
Miguel Angel Bastarrachea-Magnani, Jannie Thomsen, Arturo Camacho-Guardian +1
Two-dimensional semiconductors inside optical microcavities have emerged as a versatile platform to explore new hybrid light-matter quantum states. The strong light-matter coupling…
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…
Topological transport of mobile impurities
D. Pimenov, A. Camacho-Guardian, N. Goldman +3
We study the Hall response of topologically-trivial mobile impurities (Fermi polarons) interacting weakly with majority fermions forming a Chern-insulator background. This setting…
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…
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…
