The Institute for Theoretical Physics offers the following seminars:
Rosetta has been at comet Churyumov-Gerasimenko almost 1.5 years by now and the ten instruments on board the European Space mission Rosetta are very busy studying the comet nucleus and its coma. The two Swiss ROSINA mass spectrometers and the pressure sensors are exploring the volatile material in the coma over a wide range of heliocentric distances. In the talk I will present some of the highlights from ROSINA and other instruments on board and discuss their first implications and conclusions on the origin of our solar system material.

Evidence for dark matter is overwhelming. From experimental data we can infer that dark matter constitutes most of the matter in the Universe and that it interacts very weakly, and at least gravitationally, with ordinary matter. However we do not know what it is. Several theoretical models have been proposed that predict the existence of Weakly Interacting Massive Particles (WIMPs) that are excellent dark matter candidates. The existence of WIMPs can be tested indirectly, primarily through their annihilation or decay into photons. In this talk I’ll present the latest results on these searches.

The endeavour of quantum electronics is driven by one of the most ambitious technological goals of today’s scientists: the realization of an operational quantum computer (http://qurope.eu). We started to address this goal by the new research field of molecular quantum spintronics. The building blocks are magnetic molecules, i.e. well-defined spin qubits. We will discuss this still
largely unexplored field and present our first results.

A fundamental issue in evolutionary biology is the nature of transitions from unicellular organisms to multicellular ones. What is the advantage of being larger? What are the driving forces behind the appearance of distinct cell types? I will describe a physical approach to these questions based on the use of a lineage of green algae which serves as a model for understanding the first steps in the evolution of multicellularity.

The Large Hadron Collider (LHC) has started its second run earlier this year after a two-year shutdown. During this shutdown a lot of work was done to enable the LHC to run at a collision energy of 13 TeV, about 60% higher than in the 2010 – 2012 run. The ATLAS experiment at the LHC was also improved to be ready to analyse the data at higher energies and at the higher rates planned. I will review these improvements, and show initial results from the ATLAS experiment based on the analyses of the new data.
