Polaron Interactions and Bipolarons in One-Dimensional Bose Gases in the Strong Coupling Regime
Martin Will, Gregory E. Astrakharchik, Michael Fleischhauer
Bose polarons, quasi-particles composed of mobile impurities surrounded by cold Bose gas, can experience strong interactions mediated by the many-body environment and form bipolaro…

Strong-coupling Bose polarons in 1D: Condensate deformation and modified Bogoliubov phonons
Jonas Jager, Ryan Barnett, Martin Will +1
We discuss the interaction of a quantum impurity with a one-dimensional degenerate Bose gas forming a Bose-polaron. In three spatial dimensions the quasiparticle is typically well…
