Kolloquien

Clouds are not only fascinating to observe for their myriad of shapes, but are also scientifically challenging because their formation requires both knowledge about the large-scale meteorological environment as well as knowledge about the details of cloud droplet and ice crystal formation on the micro-scale. The ice phase in clouds remains enigmatic because ice crystal number concentrations can exceed the number concentrations of those aerosol particles that act as seeds for ice crystals by orders of magnitude.   mehr...

This colloquium gives an overview of the ideas and topics driving the newly approved research cluster STRUCTURES at Heidelberg University. This cluster is a joint project of the Department of Physics and Astronomy and the Department of Mathematics and Computer Science, as well as the Interdisciplinary Center for Scientific Computing (IWR) at our university, together with HITS, MPI-A and MPI-K.   mehr...

About 25 years ago, the first planets beyond our Solar System have been discovered. Since then, this research field exploded and over three thousands planets are known to date. Some have been declared as 'habitable' - what does this mean? What type of life do we expect there? Do we understand what life is and how it emerged?   mehr...

We will discuss a measurement of atomic parity violation in a chain of Yb isotopes and the progress in the CASPEr experiments, including the recent results of the search for ultralight dark-matter fields with zero- and ultralow-field (ZULF) nuclear magnetic resonance.   mehr...

What happens in your brain when you learn to ride a bike or memorize a new word? In this talk, I will discuss mathematical models of memory formation and learning.   mehr...

Ultra-relativistic heavy-ion collisions create extreme conditions in temperature and energy density, such that a plasma of quarks and gluons, no longer confined in color-neutral hadrons, is produced. This is the state of matter, which existed a few microseconds after the Big Bang. Nowadays we investigate the properties of the hot, strongly-interacting plasma at accelerators such as the LHC at CERN, with fascinating instruments such as the ALICE experiment.   mehr...

Es werden immer mehr Daten gesammelt, um Fußballspiele ganz genau zu sezieren. Doch wie informativ sind solche Daten eigentlich? Auf welche Art und wie gut lassen sich damit Spielergebnisse vorhersagen? Welche Rolle spielt eigentlich der Zufall?   mehr...

An overview is given on recent measurements with extreme precision on single or few cooled ions stored in Penning traps. On the one hand, mass measurements provide crucial information for atomic, nuclear and neutrino physics as well as for testing fundamental symmetries. On the other and, g-factor measurements of the bound electron in highly-charged hydrogen-like ions allow for the determination of fundamental constants and for constraining Quantum Electrodynamics.   mehr...

One of the most surprising aspects of quantum mechanics is that under certain circumstances it does not allow individual physical systems, even when isolated, to possess properties in their own right. This feature, first clearly appreciated by John Bell in 1964, has in the last three decades been tested experimentally and found (in most people's opinion) to be spectacularly confirmed.   mehr...

Superconductivity is one of the most fascinating quantum states of matter. Almost half a century passed between the discovery of superconductivity by Kamerlingh Onnes and the theoretical explanation of the phenomenon by Bardeen, Cooper and Schrieffer (BCS).   mehr...

Unser Universum dehnt sich immer schneller aus. Dieser Effekt wurde von Astronomen sehr präzise vermessen. Ungefähr 70% der Energie- und Massendichte im Universum sind derzeit dafür nötig, aber unklar ist, woher diese Energie kommt.   mehr...
