STRUCTURES Member Felix Joos receives Lautenschläger Junior Researcher Prize

We congratulate Felix Joos on receiving the Lautenschläger Junior Researcher Prize! Manfred Lautenschläger, the award sponsor and an Honorary Senator of Heidelberg University, describes him as an “enormously productive young researcher, who with creativity, self-determination and technical flexibility is tackling major questions in theoretical computer science and discrete mathematics”.

Since March 2020, Felix Joos is Junior Professor at the Institute for Computer Science, leading the group Theoretical Computer Science and joined STRUCTURES in July 2021. He recently attracted attention with his solution to the “Oberwolfach problem” (2018) and a paper on the “kissing number” (2019).

The festive presentation is to take place on 7 May 2021 as a virtual event, open to the public, and will be livestreamed from the Great Hall of the Old University starting at 17:00. It is accessible via the portal heiONLINE of Heidelberg University.

See press release from April 29, 2021.

CP7 Lunch Seminar - Summer Term 2021

We cordially invite you to the newly founded CP7 lunch seminar on selected Wednesdays during the semester. This seminar is an informal meeting for members and anyone who might be interested. Participants take turns at illustrating their area of research or a neighboring field, in 30-minute talks aimed at a broader audience. The goal is to stimulate discussions and explore possible collaborations at the interface between Mathematics and Physics.

For the updated schedule and more information, please visit the CP7 Seminar webpage.

Girl's Day 2021 with STRUCTURES

Discovering physics in a whole new light was the aim of Girls'Day, April 22. At this day it was possible to look behind the curtain of the scientific work of the department of physics and astronomy at Heidelberg University. Welcomed by the dean of the department for physics and astronomy, 120 young girls from all over Germany took part in twelve extraordinary online workshops with diverse topics such as black holes, programming with robots, mysteries of light and the universe.

We thank all participating scientists and are looking forward to taking part next year again. The Girls`Day was jointly supported by STRUCTURES, the Collaborative Research Centre 1225 "Isolated Quantum Systems and universality in extreme conditions", the Collaborative Research Centre 881 "The Milky Way System" and the HighRR Research Training Group.

Watch the introductory video by some of our YRC members about the daily life of a scientist here.

STRUCTURES welcomes four new members

We are very happy to welcome our four new members Jan Johannes, Philipp Preiß, Johannes Schemmel and Fabian Schneider to STRUCTURES. They excellently represent the rich diversity of research areas of the STRUCTURES community. Jan Johannes, leading his group "Statistics of Inverse Problems", is Professor at the Institute for Applied Mathematics. Junior group leader Philipp Preiß from the Kirchhoff-Institute for Physics leads a new project funded by the ERC starting grant "UniRand - Random Unitarities in a Rapid Optical Lattice Simulator". Johannes Schemmel, working on neuromorphic computing, is head of the "Electronic Vision(s) Group" at the Kirhoff-Institute for Physics. Fabian Schneider is Junior group leader of the "Stellar Evolution Theory" group at the Heidelberg Institute for Theoretical Studies.

New STRUCTURES Professorship on Experimental Physics

We are happy to announce that Dr. Lauriane Chomaz has accepted the new STRUCTURES Tenure-Track-Professorship on Experimental Physics. Professor Chomaz, a world leading expert on quantum fluids, explores their behavior using ultracold assemblies of atoms. She joined the STRUCTURES community this February.

Research: The Role of Turbulence in the Birth of Stars

STRUCTURES member Ralf Klessen investigates interstellar gas clouds, as part of an international cooperation.

New level computer simulations reveal the role of turbulence in interstellar molecular clouds in star formation. In their publication, the authors show how their results allow to draw conclusions how this turbulent movement transitions from the supersonic to subsonic regime

The work of this international research team was led by scientists of the Center for Astronomy of Heidelberg University (ZAH) and of the Australian National University in Canberra. The simulations took place at the Leibniz Supercomputing Centre of the Bavarian Academy of Science and Humanities.

STRUCTURES members Carsten Rother and Ullrich Köthe participate in the European Laboratory for Learning and Intelligent Systems.

The great potential of artificial intelligence (AI) and machine learning for the life sciences – from basic research in biology to medical applications – has to date largely been neglected.
To leverage that potential in future, researchers from Heidelberg University, the German Cancer Research Center, and the European Molecular Biology Laboratory have founded a new research unit. It aims to support AI research in the life sciences and forge international links with activities in Heidelberg. The unit is part of the European Laboratory for Learning and Intelligent Systems (ELLIS). ELLIS Life Heidelberg will initially be funded by the founding institutions for five years.

Physics of the Quark-Gluon Plasma with Mauricio Martinez Guerrero

Title: Initial state fluctuations of QCD conserved charges in high energy nuclear collisions
Abstract: We initialize the Quantum Chromodynamic conserved charges of baryon number, strangeness, and electric charge arising from gluon splitting into quark-antiquark pairs for the initial conditions of relativistic heavy-ion collisions. A new Monte Carlo procedure that can sample from a generic energy density profile is presented, called Initial Conserved Charges in Nuclear Geometry (ICCING), based on quark and gluon multiplicities derived within the color glass condensate (CGC) effective theory. We find that while baryon number and electric charge have nearly identical geometries to the energy density profile, the initial strangeness distribution is considerable more eccentric and is produced primarily at the hot spots corresponding to temperatures of T≳ 400T ≳ 400 MeV for PbPb collisions at √s N N = 5.02 TeV.

'Almost a PhD' lecture Series.

Upcoming talk: Monday, July 20, 18:15, Linda Shen: Universelle Dynamik & Thermalisierung in isolierten Quantensystemen.
The talk will be in German this time, as this will be the language of Linda's defence.

About the 'Almost a PhD' lecture series:
In the 'almost a PhD' talks, PhD students shortly before their defence can practice their PhD talk. The presentation will be followed by questions and if wanted a short round of feedback. In this format PhD candidates benefit by practising their talk in front of a live audience and listeners are presented with understandable and hopefully high quality talks about a broad variety of current research topics. And if you are currently in your PhD yourself, you can collect ideas for your own talk in the future!
After the talk is finished and all questions are answered we would love to invite everyone to a virtual get-together. Grab a beer or snacks in front of your computer and have an informal discussion or chat.
If your defence is coming up and you are keen to practice your talk yourself, write us a mail with your topic and your preferred date. We will supply you with a 'drawing pad' that can be connected to a computer, to simulate an actual blackboard presentation. Speakers can borrow one of these pads and use it for their talk.
