The effect of boson-boson interaction on the Bipolaron formation
Jonas Jager, Ryan Barnett
Impurities immersed into a surrounding ultra-cold Bose gas experience interactions mediated by the surrounding many-body environment. If one focuses on two impurities that are suff…

Stochastic-field approach to the quench dynamics of the one-dimensional Bose polaron
Jonas Jager, Ryan Barnett
We consider the dynamics of a quantum impurity after a sudden interaction quench into a one-dimensional degenerate Bose gas. We use the Keldysh path integral formalism to derive a…
