Kolloquium der 39. Heidelberger Graduiertentage - Hans Jensen Invited Lecture
Following LIGO's discovery last year of a gravitational-wave signal from a pair of merging black holes, it was suggested that such black holes might make up the cosmic dark matter. The idea was supported by a remarkable coincidence between the merger rate implied by LIGO and the rate at which such black holes should merge, if they were to make up the dark matter.

I will present an overview of where we stand in the physics of high energies and
ultrasensitive experiments, mentioning developments from Large Hadron Collider
experiments and elsewhere, and give an assessment of what comes next. I will bring
plenty of questions, and look forward to hearing yours!

The ‘standard’ model of cosmology is founded on the basis that the expansion rate of
the universe is accelerating at present —
as was inferred
from the Hubble diagram of
Type Ia supernovae. There exists now a much bigger database of supernovae so we
can perform rigorous statistical tests to check whether these ‘standardisable candles’
indeed indicate cosmic acceleration.

The construction of ever larger and costlier accelerator facilities has its limits, and new
technologies will be needed to push the energy frontier. Plasma Wakefield
acceleration
is a rapidly developing field and is a promising candidate technology for
future high-energy accelerators. The AWAKE collaboration is pursuing an approach to
accelerate electrons to the TeV energy regime in a plasma.

Dass Gravitation überhaupt eine Antwort auf eine theoretische Frage ist -- und nicht
etwa nur ein geschicktes Postulat zur Modellierung einer der vier bekannten
fundamentalen Kräfte -- lässt sich aus einem erstaunlichen Zusammenspiel von
bereits
im
Grundstudium
bekannten
Fakten
und
einigen
wenigen
(aber
hochspannenden!) Spezialkenntnissen verstehen.

Festkolloquium anlässlich des 80. Geburtstags von Prof. Dr. Jörg Hüfner
Collisions of heavy nuclei at high energies produce deconfined
quark-gluon matter, a
state of matter which prevailed in our Universe in its first 10 microseconds of existence.
I will discuss how properties of this state of matter as well as the still-mysterious
transition to hadrons with confined quarks and gluons are currently investigated with
experiments at the Large Hadron Collider at CERN.

Lebende Materie ist außerordentlich dynamisch und organisiert sich spontan
in komplexen Mustern und in räumlichen Strukturen. Eine
fundamentale Frage der
Biologie
ist es zu verstehen,
wie Zellen räumliche Symmetrien brechen. Beispiele
zellulärer
Symmetriebrechung sind Zellpolarität und Zellchiralität. Solche zellulären
Asymmetrien spielen eine wichtige Rolle bei der Entstehung komplexer Organismen.

Mapping out the ''phase'' boundary between the low temperature
confining phase of
ordinary hadronic matter and the phase of an
asymptotically free gas of quarks and
gluons is one of the central goals of current theoretical studies of strong interaction
matter as well as experiments at the Relativistic Heavy Ion Collider (RHIC) at
Brookhaven
National Laboratory and the Large Hadron Collider (LHC) at CERN.

Since their discovery in 1971 the superfluid phases of Helium-3 have
proved to be the ideal testing ground for many fundamental concepts of
modern physics. Phenomena such as anisotropic Cooper pairing, p-wave states,
chirality, macroscopic quantum coherence, spontaneous breaking of high symmetries,
and exotic topological defects are not only an important enrichment of the physics of
condensed matter, but also provide important links to particle physics, defect formation
in the early universe and, most recently, quantum turbulence.

Weihnachtskolloquium
In den
letzten Jahren wurden
mit Hilfe der Stringtheorie neue, überraschende Verbindungen
zwischen Quantenfeldtheorien und höherdimensionalen Gravitationstheorien entdeckt. Diese
holographischen
Dualitäten verbessern unser Verständnis der fundamentalen Theorien der
Natur und haben darüber hinaus zahlreiche Anwendungen.
Insbesondere ermöglichen sie
eine revolutionär neue Sicht auf stark gekoppelte Quantensysteme in vielen Bereichen der
Physik.

Festkolloquium "10 Jahre HCI"
In this talk I will present the work we are conducting in the Visual Learning Lab
Heidelberg, which is at the intersection of computer vision and machine learning. After
a gentle introduction to classical supervised machine learning, I will explain our latest
research results, which often do not fit in this classical form.

Smoking can kill! Our current energy system is
heavily smoking. In view of critical
CO
2
emissions and depleting
conventional resources, a transformation towards a sustainable energy system
is needed. Applied Theoretical Physics and the Physics of Complex
Networks are able to contribute to the solution of this grand challenge.
We discuss a simple
network model, which describes a future European electricity system with a high share of wind and solar power generation.

Gemeinsames Kolloquium mit Karlsruhe
Very high energy (VHE) gamma ray astronomy -
at photon energies of 100 GeV and beyond - has developed in giant steps, with the number of known cosmic VHE gamma ray sources
approaching 200.
Systems of large imaging atmospheric Cherenkov telescopes have
played a key role in this development.
