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…
Magnetic domains stabilized by symmetry-protected zero modes
Pavel Kos, Dominik S. Wild, Kristian Knakkergaard Nielsen
Understanding mechanisms for the breakdown of thermalization in closed quantum systems is a central problem in quantum many-body physics. We demonstrate strong nonergodic behavior…
Hole and spin dynamics in an anti-ferromagnet close to half filling
Magnus Callsen, Jens H. Nyhegn, Kristian Knakkergaard Nielsen +1
The interplay between charge and spin dynamics is at the heart of strongly correlated materials. Inspired by recent quantum simulation experiments, we develop a conserving diagramm…
