DQ-mat Newsletter #18 (June 2024)
Dear DQ-mat members,
In a few days, on 1 July, the third funding period of DQ-mat begins! The approval by the DFG is a great success, which was only possible thanks to the enormous commitment of all members. Many thanks once again to this fantastic team. We will celebrate this achievement on August 21st, starting with a series of hot topic talks, a general assembly including elections, and a BBQ.
We have already achieved a great deal in the first two funding phases. We will now use the next four years to continue what we have started and do our part to answer the unsolved questions of physics.
And summer is just around the corner. We wish you all a holiday to remember.
With best regards
Piet Schmidt, Klemens Hammerer, Malte Niemann, Christian Engel
Funding
Applications for lump sum funds
DQ-mat receives lump sum funds 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.
Jour Fixe - Winter Semester 2023/24
Colloquium
The DQ-mat colloquium will also take place in the coming semester. Dates and speakers are still being finalised and will be announced on the website webpage in good time.
