Here...10 December 2024|ilp SengstockSingle Fermionic Yb atoms in optical tweezersPhoto: UHH/PetersenAfter successful optimization of trapping and imaging of individual bosonic 174Yb atoms we have now succeeded in trapping fermionic 173Yb atoms in...22 August 2024|ilp SengstockFirst single Yb atoms in optical tweezers in Hamburg!Photo: UHH/PetersenFor the first time we have loaded individual 174Yb atoms in a small tweezer array at a wavelength of 532nm. Atoms are imaged on the 1S0 -3P1...26 April 2024|ilp SengstockWe welcome our 3D MOT back to the labPhoto: UHH / SponseleeShortly after the 2D MOT we trap atoms again int the 3D MOT. We now use diagonal beams inclined by 59 degrees with only 8mm diameter - signififcantly...5 April 2024|ILP SengstockCooling dynamics of a free ion in a Bose-Einstein condensatePhoto: L. Oghittu / Ph. Wessels-StaarmannWe investigate the dynamics of an ion moving through a homogeneous Bose-Einstein condensate (BEC) after an initial momentum is imparted. For this, we...8 February 2024|ilp SengstockBlue 2D MOT back againPhoto: UHH/ SponseleeAfter extensive rebuild of the main experiment and the cooling laser systems we have found the 2D magneto-optical trap (MOT) again! The first step in...12 September 2023|ilp SengstockSuccessful suppression of servo bumps by more than 20 dBPhoto: UHH / HerbigPhilipp Herbig has successfully finished his Bachelor’s project on the topic of servo-bump phase noise suppression.
