Observation of low-lying impurity states in Bose-Einstein condensates
A. M. Morgen, S. S. Balling, M. T. Strøe +6
Impurities embedded in a Bose-Einstein Condensate (BEC) of 39K atoms are investigated with a pump-probe ejection spectroscopy sequence. The spectroscopic signal exhibits a strong f…
Three-body Physics in the Impurity Limit of 39K Bose-Einstein Condensates
A. M. Morgen, S. S. Balling, M. T. Strøe +4
Loss spectroscopy is a key tool for investigating systems where important system parameters are linked to intrinsic resonant loss processes. We investigate loss processes of impuri…
Life and death of the Bose polaron
Magnus G. Skou, Kristian Knakkergaard Nielsen, Thomas G. Skov +6
Spectroscopic and interferometric measurements complement each other in extracting the fundamental properties of quantum many-body systems. While spectroscopy provides precise meas…
Observation of a Lee-Huang-Yang Fluid
Thomas G. Skov, Magnus G. Skou, Nils B. Jørgensen +1
We observe monopole oscillations in a mixture of Bose-Einstein condensates, where the usually dominant mean-field interactions are canceled. In this case, the system is governed by…
Non-equilibrium quantum dynamics and formation of the Bose polaron
Magnus G. Skou, Thomas G. Skov, Nils B. Jørgensen +5
Advancing our understanding of non-equilibrium phenomena in quantum many-body systems remains among the greatest challenges in physics. Here, we report on the experimental observat…
