The ability to control and sense the properties of solid-state materials on the nanoscale lays the foundation for both groundbreaking fundamental discoveries and technological applications. By employing advanced measurement techniques, we are pushing the limits of spatial resolution and investigate the intrinsic properties of solid-state nanosystems. These encompass 2D materials and surface spin textures in thin-film systems, as well as single quantum emitters for quantum technologies and integrated circuits controlled by nano-earthquakes. We aim for a profound understanding of the interactions between light, spin, charge, and matter, with the ultimate goal of attaining comprehensive control over nanomaterials in the quantum domain.17.10.2024 Dr. Pauline Gagnon (CERN)
The tragic destiny of Mileva Maric Einstein
What were Albert Einstein's first wife’s contributions to his extraordinary productivity in the first years of his career? A first biography of Mileva Marić Einstein was published in Serbian in 1969 but remained largely unknown despite being translated first in German, then in French in the 1990’s. The publication of Mileva and Albert’s love letters in 1987 revealed how they lived together while two recent publications shed more light on Mileva Marić’s life and work. I will review this evidence in its social and historical context to give a better idea of her contributions. In this presentation, I avoid all type of speculation and do not attack Albert Einstein personally, but rather strictly stick to facts. The audience will be able to appreciate why such a talented physicist has been so unkindly treated by history.24.10.2024 Prof. Dr. Svetlana Gurevich

Dynamics and control of optical pulses in time-delayed micro-cavities
Real-world complex systems can be strongly influenced by time delays due to unavoidable finite signal propagation speeds and time-delayed dynamical systems have proven to be a fertile framework for the modeling of nonlinear phenomena. Nonlinear laser dynamics is one of the fields where time-delayed system are frequently employed to model the arising complex dynamics. In this talk, we will explore the use of time-delayed models to describe the dynamics of ultrashort pulses in optical micro-cavities, highlighting their potential for optical frequency comb generation.

QCD Frontiers from TeV to MeV Scales
The Large Hadron Collider (LHC), which is gearing up for its high-luminosity phase, is stress testing the Standard Model of particle physics at an unprecedented level of detail. I give an overview of major recent highlights of the LHC experimental program on the TeV precision frontier, ranging from the direct observation of Higgs Yukawa interactions -- the fifth force of Nature -- and rare phenomena involving top quarks, including their quantum entanglement, to ultra-precise measurements of the mass of the W boson. In particular, I review some of the theory advances in Quantum Chromodynamics (QCD) making this progress possible, many of which concern the physics of transverse-momentum distributions (TMDs). I then relate these ideas to one of the least understood aspects of the Standard Model, the deeply nonlinear dynamics of quarks and gluons confining into color-neutral hadrons at a scale of hundreds of MeV. I showcase how heavy (bottom and charm) quarks provide a unique view into this phenomenon of hadronization by effectively serving as static sources of the gluon field, and outline the opportunities that heavy hadrons offer towards establishing a future Quantum Information Theory of hadronization.

Axion inflation
Cosmological inflation provides initial conditions for the subsequent `big-bang’ era consistent with observational data. After an overview of the general framework and basic phenomenological predictions, we explore the theoretical motivations behind a specific class of inflationary models known as axion inflation. The coupling between axion inflation and gauge fields can significantly enhance the amplitude of these fields, leading to diverse observational consequences, including non-Gaussianity at Cosmic Microwave Background (CMB) scales, a gravitational wave background detectable at Pulsar Timing Array (PTA) and interferometer scales, and the potential formation of Primordial Black Holes. We conclude by presenting recent results in the strong back-reaction regime, where gauge field amplification alters the inflationary dynamics in a complex, non-trivial manner.
