B02 Summer Hackathon 2026

Mon, 17 Aug 2026 00:00:00 +0000

In August 2026, the [“B02”] project team, members of other NuMeriQS projects and external collaborators got together at the Institute of Computer Science at the University of Bonn for four days of intense work and discussion on the Kronos library for lattice field theory.
Development of the library is at a crucial stage with multiple essential features encompassing around 40k lines of code close to being ready to merge.
Because of their complexity and central nature, many design decisions need to be discussed in depth which is really only possible in person.
NuMeriQS funding enabled external collaborators to join for the entire duration of the hackathon, making the event highly productive and successful.

Many thanks to the Institute of Computer Science for giving us access to one of their computer pools!

Lattice 25 Plenary by Stefan Krieg

Thu, 06 Nov 2025 00:00:00 +0000

NuMeriQS project leader Stefan Krieg has been invited to give and delivered a plenary talk at the 42 International Symposium on Lattice Field Theory on Machines and Exascale Computing.

The Lattice Conference is the central yearly conference for Lattice QCD and related fields. In 2025 it took place in Mumbai, India.

Second NuMeriQS Retreat

Mon, 15 Sep 2025 00:00:00 +0000

From September 15 to September 18, 2025 we met for the second NuMeriQS Retreat, which took place at Kloster Steinfeld in the Eifel.

The first day was reserved for the NuMeriQS early career researchers. On the second day we had two very intersting talks by external researchers: Julia Westermayr and Jennifer Schober. Moreover, we had two introductory presenatations, one by Frank Neese on the coupled cluster algorithm and a second one by Thomas Luu and Carsten Urbach on Lattice QCD for dummies. The status of the single projects was presented in short talks, amended by posters. The method convenors presented ideas on how to extend their applicabilities.

Trento Workshop on Hamiltonian Lattice Gauge Theories

Mon, 01 Sep 2025 00:00:00 +0000

NuMeriQS co-organised from September 1 to September 5, 2025 a workshop at the ECT* in Trento, Italia on a topic at the heart of NuMeriQS: Hamiltonian Lattice Gauge Theories: Status, Novel Developments, and Applications.

With Christian Bauer, Stefan Kühn, Enrico Rinaldi and Martin Savaga we could invite internationally highly visible researchers to deliver keynote lectures at the beginning of the first four workshop days. The workshop was perceived as very useful: in a very open and collaborative atmosphere the current status of the field was assessed, and novel ideas were discussed.

NuMeriQS members successful in Excellence Strategy

Wed, 21 May 2025 00:00:00 +0000

The University of Bonn won support for eight clusters of excellence. Project leaders of NuMeriQS play central roles in the clusters Matter and Light for Quantum Computing: ML4Q, HCM, and Color meets Flavor.

Congratulations to all successful cluster initiatives!

Aniket Sen, a postdoctoral researcher in NuMeriQS, is part of a team which has won the most exciting project price awarded at the occasion of the first birthday of Marvin, the supercomputer of the University of Bonn. The second price was awarded to Katrin Drysch, a NuMeriQS doctoral researcher in the group of Barbara Kirchner. More details can be found on the event webpage.

Physics Show on Tour to Ljubljana and Trieste

Mon, 07 Oct 2024 00:00:00 +0000

From September 21-29, 2024 the The Physics Show of the university Bonn has been on its first international tour since the outbreak of the COVID-19 pandemic.

The group of 20 students and university employees lead by Prof. Herbert Dreiner and Timo Poller visited Ljubljana and Trieste. In both places we performed the Particle Physics Show What’s (the) matter? twice. The shows in Ljubljana took place in the theatre Cankarjev Dom on September 23, while in Trieste the shows were performed at the Revoltella Museum on September 27. All the shows were sold out and very well perceived by the audience.

In addition, the physics students and Postdocs of the Universtiy of Ljubljana were given the opportunity to attend a workshop under the supervision of the Physics Show members. In small groups they discovered a number of unusual physical experiments hands on and they designed short sketches demonstrating and explaining the experiments in an entertaining fashion.

The Physics Show is co-funded by the CRC 1639 NuMeriQS.

First NuMeriQS Retreat

Wed, 02 Oct 2024 00:00:00 +0000

From September 31 to October 29, 2024 the first NuMeriQS Retreat took place at the Bethe Center for Theoretical Physics.

With Martin Savage (Seattle) and Moritz Helias (Aachen and FZJ), we had two inspiring external speakers. With presentations by all projects the communication and interaction between the diverse NuMeriQS working groups was further fostered.

During the poster session questions could be discussed in more detail. Moreover, early career researchers had the possibility to discuss their research with experienced NuMeriQS scientiests

CRC 1639 NuMeriQS Kick-off meeting

Wed, 17 Apr 2024 00:00:00 +0000

On April 27, 2024, we officially kicked of the efforts in NuMeriQS with two very interesting talks by Prof. Anthony Kennedy (University of Edinburgh) and Prof. Peter Coveney (London).

Prof. Kennedy, as one of the inventors of the Hybrid Monte Carlo (HMC) algorithm, gave an interesting historical review of the HMC and its modern applications. Prof. Coveney, a chemist by profession, introduced the audience to uncertainty quantification and its use in large scale molecular dynamics simulations.

Apart from officially starting operation - even though it started of course beginning of April, one of the purposes of the meeting was to introduce the CRC to the wider public of the University of Bonn, and more specifically to the contributing departments. We are happy that the heads of all the contributing departments, i.e. chemistry, computer science, mathematics, and physics, participated in the meeting. Moreover, the TRA Simulation Modelling and the TRA Matter were represented.

There were very interesting discussions during the reception, which took place after the two scientific talks. We look forward to about four more interesting years.

For more details see the meetings indico page.

The corresponding presentations will be accessible to a broader audience. After the scientific part we would be happy to discuss with you sharing some food and drinks.

Please register on the meeting’s indico page as we have only a limited number of places available.
