In this talk I will provide a theoretical perspective on low-energy searches for physics
beyond the Standard Model involving hadrons and nuclei. After presenting an
overview of this exciting field, I will focus on two probes that illustrate the breadth of
the field. more...

The past 25 years have revealed a diversity of exoplanets far beyond what was
imagined from the limited sample in the Solar System. With new and upcoming
observing facilities and a rapidly growing number of nearby planets, we are beginning
to bring this diversity into focus, with detailed follow-up characterization of the planets’
atmospheres. more...

Neutron stars are among the most compact objects in the Universe and the detection
of gravitational waves and electromagnetic signals from the merger of two neutron
stars in 2017 has been a revolution. This breakthrough observation enabled studies
about the history of our cosmos, the formation of heavy elements, and the physics on
subatomic scales. Since then, another binary neutron star merger was seen in April
2019, and in January 2020, the detection of two black hole ? neutron star mergers
completed the picture. more...

Scale invariance, a concept first introduced in high energy physics, has recently found
many applications in the physics of quantum gases and fluids. It applies to strongly
interacting Fermi gases, to two-dimensional Bose gases, and to few-body systems
exhibiting the so-called Efimov effect. more...

Folding the World: Infinite growth on a finite planet
Prof. Dr. Anders Levermann
Institut für Klimafolgenforschung, Potsdam
We are at the end of an age – the age of expansion – and we need a new narrative
for the next step. The limitations of our physical Earth collide with the necessity of
rapid societal development. Accepting the harsh reality of both, we face a dilemma.
The desperate call for renunciation and recession is understandable but
counterproductive, because it does not resolve the dilemma. Where economists
struggle, physicists know the answer: there is infinite opportunity in finite space.
Therefore the mathematical concept of folding could provide a solution, because it
allows for infinite motion in a finite world – through growth into diversity. Not growth
into more, but into different – and not theoretically or esoterically but in a practical,
applicable manner. more...

I will first discuss how gravity can manifest itself geometrically. Using different
geometrical properties of a spacetime I will formulate General Relativity in different but
equivalent ways. This will allow me to introduce a generalization of gravity with distinct
and interesting implications for cosmology and black hole physics and how we can
test them. more...

Soft exoskeleton or exosuits have been introduced in the last decade as possible
candidates to overcome the limitations and acceptability of wearable technology.
Although the Exosuits initially promised tangible improvements, yet their soft wearable
architecture presents strong drawbacks, placing this technology more in a
complementary position rather than on a higher step of the podium respect to their
predecessors. more...

In these days, we are witnessing amazing progress in both the variety and quality of
platforms for quantum computation and quantum communication. Since algorithms
and communication protocols designed for traditional 'classical' hardware do not
employ the superposition principle and thus provide no gain even when used on
quantum hardware, we are in need of developing specific quantum algorithms and
quantum communication protocols that make clever use of the superposition principle
and extract a quantum advantage. more...

The dynamics within the Standard Model of particle physics play a central role in the
properties of not only the microscopic world but also the biggest structures of our
universe. The Higgs boson, for example, plays a critical role is how particles obtain
their masses but also perhaps to how our universe evolved. more...

he performance of electronic chips is to a large extent limited by the electrical resistance, which sets the
maximum operation frequency and the minimum power consumption. It is expected that by replacing part of the
electronic circuit by photonics, these limitations could be alleviated. For this goal, an integrated light source is
required. more...

The dynamics of the early universe and black holes are fundamental reflections of the
interplay between general relativity and classical/quantum fields. The essential
physical processes occur when gravitational and/or field interactions are strong and/or
quantum effects are important. These situations are difficult to observe and impossible
to experiment with, while the existing theoretical approaches are based on
approximations that are in need of experimental verification. more...

Mechanical stability and shape changes of cells are determined by the dynamic interplay
of four distinct cytoskeletal networks, made of actin filaments, microtubules, intermediate
filaments and septins. These four filamentous systems contribute different structural and
dynamical properties, enabling specific cellular functions. more...
