QURS Days 2025

17 Feb 2025, 08:30 → 20 Feb 2025, 20:00 Europe/Berlin

Harbor, building 610 (Campus Bahrenfeld)

The second edition of the "QURS Days" will be organized in February 2025 by the Early Career Council and the QURS management. All doctoral researchers are welcome to join our graduate week.

Within the first three days introductory and advanced lecture courses will be held in each QU area:

• Gravitational Waves 
• Higgs Physics 
• Dark Matter
• Quantum Theories 

Additionally, two key skills courses will be offered on the topics leadership and software development. 

A poster session will be held by our QURS members, and the DESY Startup Labs will present their work.

Our social program will feature a Science Pub Quiz on Tuesday, 18 February 2025, with drinks and pretzels provided.

All researchers at CHAMPP (Center in Hamburg for Astro-, Mathematical, and Particle Physics) are warmly invited to join this event!

Introductory course - Dark Matter: Part 1

Introductory course - Quantum Theories: Introduction to string theory for non-experts: Part 1

This course introduces basic concepts of string theory and its application to particle physics in a non-technical way. It addresses physicists or mathematicians who have not taken a string theory course before and who would like to get a general idea of why string theory is considered a leading candidate for a theory of quantum gravity and how it makes contact with concepts in particle physics and cosmology.

Convener: Timo Weigand (UNI/TH (Uni Hamburg, Institut fuer Theoretische Physik))

Key skills course I: Your Role as a Young Leader (part 1)

Convener: Matthias Mayer

Key skills course II: Best practices of software development (part 1)

Maximizing the potential of particle physics requires an investment in the software used to collect, process, and analyze the data and simulation. In particular, mindful development of software for particle physics analysis is important to ensure its robustness, efficiency, reproducibility, and in some cases, longevity. In this key skills course, we will discuss the software development life cycle and some ideas for best practices of software development. After we review the basic tools for development like computing clusters (such as the National Analysis Facility) and batch computing, we will discuss good coding practices, software testing, continuous integration, and documenting with GIT. For each of these topics, exercises that are tailor-made to the needs of QU software developers will be demonstrated, and participants will have the opportunity to practice these exercises alongside the demonstration.

Convener: Juliette Alimena (CMS (CMS Fachgruppe Searches))

Advanced course - Dark Matter. Cosmological magnetic fields: Origin, evolution, observational constraints, and relevance: Part 1

This lecture introduces cosmological magnetic fields. As they could already have been generated in the early Universe, their observational signatures offer unique insights into fundamental physics. The lecture begins by outlining the essential tools for modeling magnetized fluids, with a particular focus on magnetohydrodynamics (MHD) and MHD turbulence. Then, the discussion shifts to high-energy MHD, which is relevant for the very early Universe plasma. Here, macroscopic quantum effects are incorporated into the models, which significantly affects the evolution of primordial magnetic fields. Finally, the lecture examines the broader potential cosmological implications of primordial magnetic fields, with a specific example of their impact on the formation of dwarf galaxies.

1 Science Pub Quiz

Why should you pet your basil plant from time to time? What is the IKEA effect? And does an onion float? Since the first Science Pub Quiz in 2019, Lisa, Nikolas and Dennis ask all the really important questions and get their audience to draw obscure animals, build paper planes and google answers as fast as possible.

Everyone is welcome to join this Science Pub Quiz - conducted entirely in English!

Whether you’re an early career researcher, an experienced researcher, or just looking for a fun evening filled with quirky questions and fascinating facts, this event is for you!

Snacks and drinks will be provided from 4:30 pm on.

Register in teams of 3-5, or individually and we’ll match you with other teammates.
Registration deadline: 13 Februray, 2025 - Please contact qurs.champp@uni-hamburg.de if you would like to register after this date.
Enjoy drinks and snacks!

UHH research information system (FIS) helpdesk

In this hands-on session, all participants can visit the helpdesk directly on site and ask their questions about research information, and the system introduced at the UHH for this purpose: What data should be in the FIS? Do I have automatic access? Where is my data displayed? etc.
Uncomplicated solutions, individual assistance, and quick answers to specific questions will be offered here in a short way.

9 Non-Gaussianities in ultra slow-roll inflation

A phase of ultra slow-roll during inflation, characterized by a transient decrease in the inflaton field velocity, is known to generate large curvature perturbations on small scales that could later seed the formation of a significant population of primordial black holes. In this talk, we discuss how non-Gaussianities can arise from the non-linear relation between curvature perturbations and inflaton fluctuations and from the intrinsic non-Gaussianities of the latter, which stem from its self interactions. We discuss a numerical approach to estimate the impact of such non-Gaussianities on the tail of the probability distribution function of curvature perturbations.

10 Flows of Spin(7)-structures

We will discuss the negative gradient flow of an energy functional of Spin(7)-structures on compact 8-manifolds. The energy functional is the L2-norm of the torsion of the Spin(7)-structure. We will talk about the short-time existence and uniqueness of solutions to the flow. We will also explain how this negative gradient flow is the most general flow of Spin(7)-structures.

Speaker: Prof. Shubham Dwivedi (Universität Hamburg)
