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…
Dilute Fluid Governed by Quantum Fluctuations
Nils B. Jørgensen, Georg M. Bruun, Jan J. Arlt
Understanding the effects of interactions in complex quantum systems beyond the mean-field paradigm constitutes a fundamental problem in physics. Here, we show how the atom numbers…
Temperature dependence of an Efimov resonance in
Lars J. Wacker, Nils B. Jørgensen, Kristoffer T. Skalmstang +3
Ultracold atomic gases are an important testing ground for understanding few-body physics. In particular, these systems enable a detailed study of the Efimov effect. We use ultraco…
