QuantumFrontiers Newsletter #03 (Feb 2020)

Correct use of acknowledgement

We noticed that out of 47 registered publications only three have been correctly acknowledged. DFG demands that publications of each cluster are acknowledged in a specific way. The reason is that DFG outsourced the registration of publications and only specific words are searched for. Not following these instructions will result in the loss of the publications for your own and the merit of QuantumFrontiers. Therefore, please use this acknowledgment for QuantumFrontiers publications in order to ensure that your publication and thus your work is correctly assigned to QuantumFrontiers:

• In German: Gefördert durch die Deutsche Forschungsgemeinschaft (DFG) im Rahmen der Exzellenzstrategie des Bundes und der Länder – EXC-2123 QuantumFrontiers – 390837967
• In English: Funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy – EXC-2123 QuantumFrontiers – 390837967

The German term “Deutsche Forschungsgemeinschaft” and the number 390837967 of QuantumFrontiers are mandatory in all languages! The current and exact wording can always be found on the QuantumFrontiers website under Publications
In case you have questions or want to ensure that your wording is correct you can always contact the QuantumFrontiers office. Best practice is to contact us before submission. We normally provide you feedback within 24 hours.

Single beam grating magneto-optical trap on an atom chip
On our endeavour to simplify and shrink down quantum sensors we have collaborated with the University of Strathclyde (Glasgow, UK) to combine a grating magneto-optical trap with an atom chip. This allows to trap and cool atoms with a single beam of light which greatly reduces the complexity of the setup while keeping the advantages of the atom chip that allows for fast evaporation to Bose-Einstein condensation (BEC). We were able to trap up to 1e9 atoms in 1s and cool them subsequently to 12 µK from where they can be trapped magnetically to create the BEC. This is a significant improvement both in the achievable atom number and in the reached temperature. The similar manufacturing techniques of the atom chip and the optical grating allow for fully integrated devices that can play a key role in the development of transportable quantum sensors.
For further information or related PhD opportunities please contact Prof. Dr. Ernst M. Rasel either by phone (+49 511 762 19203) or by E-Mail (rasel@iqo.uni-hannover.de).

Successful start for the MasterClasses at the Wilhelm-Gymnasium in Braunschweig
On Saturday, 30.11.2019, Prof. Stefanie Kroker and her PhD student Florian Bruns successfully led an all-day workshop on interferometry as a kick-off to the so-called QuantumFrontiers MasterClasses. The goal of the MasterClasses is to bring QuantumFrontiers research from the labs and offices into the hands of the students. Through the MasterClasses, interested aspiring students have the opportunity to learn directly from QuantumFrontiers researchers about current scientific research and even to conduct their own experiments. The MasterClasses will be offered in Hanover and Braunschweig by Prof. Rainer Müller and Prof. Gunnar Friege together with their new group members Dr. Azadeh Ghanbari and MSc Stina Scheer, who are dedicated to establishing the MasterClasses. Further MasterClasses at Braunschweig schools are planned for the near future, and from April 2020 they will be offered at Leibniz Universität Hannover. Please find an article about the kick-off event on the webpage of the Wilhelm-Gymnasium.
