DQ-mat Newsletter #16 (September 2023)
Dear DQ-mat members,
Summer is already drawing to a close. We hope you were all able to enjoy your holidays and recover properly.
The first DQ-mat Summer School took place at the end of August. With 30 participants from all over Europe and even beyond it was a great success and gave the next generation of young scientists a deeper insight into our research. Many thanks to Naceur Gaaloul and Dennis Schlippert for organising the event.
Next week, the Seventh European Conference on Trapped Ions (ECTI) 2023 will take place in Bückeburg and in October the EQTC will bring the European quantum world to Hannover for a full week. Both events are co-organised by DQ-mat. We look forward to seeing many of you there again.
Also, the winter semester is about to start. We were again able to attract a good line-up of speakers for the colloquium. As always, you can find all the latest information on the website. At the same time, we are entering the crucial phase of the application for the third funding period of DQ-mat. The deadline is in December. We are working hard to submit a successful proposal.
With best regards
Piet Schmidt, Klemens Hammerer, Malte Niemann, Christian Engel
Funding
Applications for lump sum funds
DQ-mat receives lump sum funds of 300.000 € in 2023 to cover publication costs, foster public outreach, and to support new project ideas. How we spend this money is very important for the upcoming follow-up proposal. This is the last chance to get funding to kickstart new projects to be included in the CRC in the next funding period. Therefore, we want to encourage you to propose new project ideas that complement ongoing activities within the SFB. We have two categories of projects in mind: - Larger projects that may become part of the third funding period, ideally involving more than one SFB PI and strengthening one of the core SFB topics. They should be proposed by PIs.
- Smaller projects in which an interesting aspect (that was not part of the original proposal) of an existing project deserves further investigation, since it may become relevant for the SFB. These projects can be proposed by PhD students, PostDocs, or PIs.
You will find a simple template for the proposals in our Seafile cloud.
Applications will be reviewed in a rolling review scheme by the DQ-mat board. Hence, applications can be sent to Malte Niemann (niemann@iqo.uni-hannover.de) at any time. If you have questions concerning the application or whether you idea is suitable for funding via lump sum funds, contact Malte as well.
