Symmetries have played a crucial role in the development of the standard
model of particle physics. Moreover, they are believed to provide the key
ingredients for a unified description of all fundamental interactions. We
review the arguments that favor the investigation of these mathematical
structures and explain possible consequences for particle physics and
cosmology. more...

Man-made organic materials allow to tailor functional device properties in an
unprecedented manner. A prerequisite is the fundamental understanding of the
underlying physics. In this seminar, I will introduce some of our recent work, in which
we investigate the fundamentals of charge motion in carbon-based molecular materials
and use the gained insights to develop novel electronic functionality. more...

Festkolloquium zu Ehren von Prof. Dr. Franz Wegner

We study the force-force correlator for disordered elastic systems. We show that each
of the relevant universality classes has its own function. The nicest experiments are
for DNA unzipping and Barkhausen noise. For the latter we observe two distinct
universality classes, depending on the range of spin interactions. In all cases force-
force correlations grow linearly at small distances, while they are bounded at large
distances. As a consequence, avalanches are anti-correlated, i.e. reduced in size, at
short distances. more...

Tailored High Tc Superconductors for Power and Magnet Applications: - nm defects for kA on the km scale –

*Prof. Dr. Bernhard Holzapfel, Institut für Technische Physik, KIT Karlsruhe*

INF 308, HS 1

High field magnet applications like MRI, NMR and accelerator magnets are one of the
major success stories of superconductivity and only possible by tailoring
superconducting materials on various length scales. Besides the conventional low
temperature superconductors, cuprate based High Temperature Superconductors
(HTSC) and new superconducting materials will open completely new opportunities in
modern magnet/power applications and are currently on the way into commercial
products. more...

Finding new land expands the horizon. The same is true for new phases of matter. I
will discuss the rich landscape of strongly correlated quantum materials and their
fascinating properties, using heavy fermion compounds as a particularly versatile
platform to explore them. more...

Since the inception of agriculture by mankind about ten millennia ago, the basis of the
food supply for the human population has been the farming of field crops. However,
our conventional, biogenic agriculture (CBA) has failed to provide a reliable concept to
feed a growing population in a sustainable way. In particular CBA suffers from severe
environmental externalities - such as the massive use of land area, water for irrigation,
fertiliser, pesticides, herbicides, and fossil fuel. more...

In the scientific reports, political debates, and to a large degree also in the media, the measure
of global climate change around the world is global mean temperature rise used as the metric
to determine how humans are changing the climate by burning fossil fuels. It is, however, not
the abstract measure of global mean temperature that cause loss and damage from climate
change, instead the impacts of climate change primarily manifest through rising sea levels and
the changing risks of extreme weather events. more...

In 2015 the LIGO detectors observed, for the first time, a gravitational wave passing
through the Earth produced by the collision of two black holes. Such an event was a
milestone for astrophysics and it provided a remarkable confirmation of the general
theory of relativity. Since then, as many as ninety gravitational waves have
been observed by the LIGO and Virgo experiments, including signals from binary
neutron stars and neutron- star - black-hole binaries. more...

Nuclear halos are a fascinating manifestation of quantum physics. They belong to a
subset of low-density clustering for which most of the probability to find the halo
nucleon extends to a region of space that is classically forbidden. Their properties show
universal aspects of few-body systems such as scaling laws. Advances in the
production of radioactive isotope beams give access to loosely-bound neutron-rich
systems at the nuclear driplines, where halos are found. more...

In the 1980s, Feynman observed that many-body quantum problems seemed difficult
to solve with classical computers due to the exponentially growing size of the quantum
state Hilbert space. He proposed that a quantum computer would be a natural solution. more...
