Analyzing a Bose polaron across resonant interactions
L. A. Peña Ardila, N. B. Jörgensen, T. Pohl +3
Recently, two independent experiments reported the observation of long-lived polarons in a Bose-Einstein condensate, providing an excellent setting to study the generic scenario of…
Critical slowdown of non-equilibrium polaron dynamics
Kristian Knakkergaard Nielsen, Luis A. Peña Ardila, Georg M. Bruun +1
We study the quantum dynamics of a single impurity following its sudden immersion into a Bose-Einstein condensate. The ensuing formation of the Bose polaron in this general setting…
Ground-state properties of Dipolar Bose polarons
L. A. Peña Ardila, T. Pohl
We consider a quantum impurity immersed in a dipolar Bose Einstein condensate and study the properties of the emerging polaron. We calculate the energy, effective mass and quasi-pa…
Bipolarons in a Bose-Einstein Condensate
A. Camacho-Guardian, L. A. Peña Ardila, T. Pohl +1
Mobile impurities in a Bose-Einstein condensate form quasiparticles called polarons. Here, we show that two such polarons can bind to form a bound bipolaron state. Its emergence is…
