09:00 - 10:15
Room: SR III The Higgs boson was discovered in 2012 as the last missing piece of the Standard Model of Particle Physics. It is often seen as a key particle in our search for the origins of dark matter and the matter-antimatter asymmetry. In these lecture, I will cover basic Higgs theory, the discovery of the Higgs boson, and our state-of-the-art knowledge of the Higgs boson properties, as well as possible connections to physics beyond the Standard Model.

- Gudrun Wanner
09:00 - 10:15
Room: SR I In this lecture, we will discuss a number of fundamental questions concerning gravitational wave detection with a particular focus on the space-based gravitational wave detector LISA. With these questions and their high-level answers, we will work on an overview spanning all relevant aspects: What are gravitational waves, what is their effect, and how can they be measured? Why do we need multiple detectors on the ground and, additionally, a space-based detector (or several)? What do we learn from gravitational wave detection? What are the key differences between ground-based and space-based detectors, and how does a space-based gravitational wave detector like LISA actually work? We will substantiate the fundamental and conceptual overview with a number of technical details. For example, we will speak about Gaussian beams, laser frequency noise, time-delay interferometry, power spectral densities, the computation of LISA sensitivity curves, and many more.

Room: SR I In this lecture, we will discuss the basics of dark matter. In particular, we discuss the evidence of dark matter from astrophysical scales to cosmological scales, for instance, galaxy rotation curves, lensing, cosmic microwave background, etc. We then discuss the cosmological origin of dark matter, namely how it is produced in the first few seconds of the universe, how it evolves throughout the history of the universe, and how it affects the structure of the universe we observe today. Lastly we will briefly discuss possible ways to detect dark matter with terrestrial detectors and with astrophysical observation. This includes conventional dark matter direct and indirect detection strategies. Chair: Dieter Horns

10:45 - 12:00
Room: SR III The geometry and topology of supergravity. The term supergravity refers to a class of gravitational theories invariant under a conjectured symmetry called supersymmetry. Once considered as a potential candidate for a theory of everything, supergravity is nowadays understood as the low energy limit of string theory and as such, supergravity has played a fundamental role in our current understanding of the latter. Aside from its remarkable relevance in modern theoretical physics, supergravity has had, and continues to have, a tremendous impact on the development of differential geometry and topology. In this set of lectures, I will give an elementary introduction to four-dimensional supergravity, focusing on its most important applications to differential geometry and topology and describing some of its most salient features from a mathematical physics perspective. In particular, I will give a pedagogical introduction about how idealized exact gravitational waves naturally occur as supersymmetric solutions of four-dimensional ungauged supergravity.

13:30 - 14:45
Room: SR I Title: GW detection with PTAs Abstract: In this lecture, we will review the basics of Gravitational Waves (GWs) detection using Pulsar Timing Arrays (PTAs). We will start by discussing how GWs perturb the apparent period of pulsars and derive the famous Hellings and Downs correlation curve describing the correlation of these perturbations among pairs of pulsars. Armed with these results, we will look into methods to dig out these GW-induced perturbations from detector and astrophysical noise and characterize possible GW signals. Finally, we will review the recent results presented by several PTA collaborations claiming the presence of a GW background in the nHZ window and discuss possible interpretations of this background.

13:30 - 14:45
Room: SR III Abstract: This lecture will provide an overview of some of the main questions of modern research around the Higgs boson at the LHC and future experiments. A first part of the lectures will discuss the crucial role of the Higgs boson to probe Physics beyond the Standard Model (our current best description of Physics at high energies, but which we know to be only an effective theory of some more complete theory of Nature). In particular, we will review a number of deficiencies of the Standard Model – hierarchy problems, matter-antimatter asymmetry of the Universe, dark matter, inflation, etc. – and how these relate to the Higgs sector. Next, we will consider properties of the Higgs boson that can be accessed experimentally – its mass, decay widths, trilinear self-coupling, etc. – and what can be learnt from them. Finally, we will consider the relation between the Higgs sector, the dynamics of the electroweak phase transitions, and the evolution of the early Universe.

Room: SR I In the advanced dark matter lectures, we cover a specific class of dark matter candidate, wave dark matter. The wave dark matter encompasses a wide range of bosonic dark matter candidates whose mass is smaller than several electron-volt scales. Being that light, it behaves similar to classical waves rather than a particle, offering unique phenomenology across scales. We will discuss some of the theoretical motivations of wave dark matter. We will also discuss its behavior in the early universe, e.g. how it is produced. Furthermore, we will discuss unique phenomenological consequences of wave dark matter over astrophysical and cosmological scales, emphasizing its differences and similarities with usual particle dark matter. Finally we will discuss several detection strategies for wave dark matter.

Room: SR III The geometry and topology of supergravity. In this set of lectures, I will give an introduction to the ongoing quest of discovering the mathematical theory of four-dimensional ungauged supergravity and developing its potential applications to geometry and topology. In particular, I will use the cohomology of an appropriately chosen locally constant sheaf to implement the Dirac- Schwinger-Zwanziger integrality condition on four-dimensional classical ungauged supergravity, interpreting it geometrically to obtain its duality-covariant, gauge-theoretic, differential-geometric global model. Using this construction, I will prove that four-dimensional bosonic ungauged supergravity is completely determined by a choice of polarized Siegel bundle defined over the total space of a vertically Riemannian submersion equipped with a complete Ehresmann connection, showing that its gauge sector reduces to a polarized self-duality condition for connections on the underlying polarized Siegel bundle. Furthermore, I will explore the continuous and arithmetic U-duality groups of the theory, characterizing them through short exact sequences and realizing the latter through the automorphism group of the underlying Siegel bundle acting on its adjoint bundle. This elucidates the geometric origin of U-duality and justifies its miraculous existence in supergravity as a gauge group. Finally, and time permitting, I will discuss the structure of a simple class of supersymmetric solutions in supergravity, explaining how the concept of idealized gravitational wave arises naturally in this context

Room: SR II Introduction to PHYSnet and UHH GPU-Ressources The PHYSnet-RZ as well as the UHH-RRZ each provide compute resources, including GPUs, for you. This talk will provide you with an overview of the available resources, their differences and individual target use-cases and how-to access them. We will focus on GPUs in particular, as this type of accelerator hardware currently receives a lot of attention due to its particular benefits for increasingly popular machine-learning use-cases. We will discuss GPU's potential in speeding up your computations along with which use-cases do or don't benefit from including GPUs and why that's the case. The talk will include a short live demonstration on how-to access the PHYSnet compute cluster, setup a common base-environment for machine learning tasks with Python and run a tiny example compute job using GPUs.

15:15 - 16:30
Room: SR IV As academic leaders, your role is to empower your students and group members and help them tap into their full potential to perform at their best. The academic environment has specific additional requirements as people work under extremely high uncertainty with long periods of delayed gratification and limited resources. With these specific needs in mind, the aim of this skill-building course is to help you navigate the unique demands of academic leadership with more confidence and impact. We will explore evidence-based insights on leadership from positive psychology, learning research, and contemporary neuroscience to understand the principles behind effective academic leadership. We will discuss helpful action-based practices (including practices from agile frameworks) that will enable you to communicate and support your students and research group members more effectively. Depending on the need of the audience, we will be able to investigate topics such as motivation, mindset, emotional competence, communication, feedback, progress tracking, and coaching through challenges.
