A beautiful BEC transition in the lab

We observed this beautiful BEC transition in the lab on the 16th of September. The BEC is created with the help of a so-called dimple, a very tightly focused laserbeam.

High sensitivity magnetometry in the Hires lab

One of the main research interests of the experimental team is to utilize the atomic Faraday effect to measure properties of our atomic clouds. In recent work we have built a magnetometer capable of measuring magnetic fields to the precision of 2 nT. Taking into the cycle time of the experiment of about 30 s, the sensitivity of our magnetometer amounts to 12 nT/sqrt(Hz).

Paper on the ArXiv: Mapping of BEC phase diagrams

On the 11th of July we just submitted a preprint on the ArXiv of our new paper Measurement-enhanced determination of BEC phase diagrams. Find out how to utilize Faraday imaging, to enhance the performance of your ultracold atoms experiment, here: http://arxiv.org/abs/1607.02934.

Making BEC's remotely!

Over the summer, optimal control experts; an experimentalist, and a young student have had remote access to our experiment in order to create as large BECs as possible. Stay tuned for the exciting results.

First observation of Larmor precession in the lab!

We observed Larmor precession of atoms in the lab on the 23rd of June. Our atoms are magnetized, and when they are abruptly exposed to a magnetic field, pointing in a different direction than their magnetization, the start rotating around this external field. This effect can be used to measure magnetic fields very precisely.

Søren Christensen defends masters project

We congratulate our masters student Søren Christensen on fulfillment of his masters degree, with a project entitled Step-by-step Optimization of the Production of Ultra Cold Atoms, defended on the 6th of May 2016. Thank you for your contribution to the understanding of the fundamentals of our experiment, the MOT and the evaporation process.
