Tension, crisis, or hot air --- The status of cosmology

Increasingly precise measurements in observational cosmology challenge our current understanding of the evolution and composition of the Universe. Local and cosmic inference of the Hubble-Lema\^itre expansion rate disagree by a statistically significant amount. The strength of large-scale clustering as measured by means of weak gravitational lensing is in tension with its inferred strength from the study of the cosmic microwave background fluctuations.
Other tensions include anomalies of the cosmic microwave sky at the largest angular scales and the cosmic radio dipole. In this colloquium I will review the status of modern cosmology in view of these observational puzzles.

The perfect wave

Many materials provide quite remarkable features in terms of their mechanical, electronic, magnetic or optical properties. Semiconductor structures and layered systems thereof for example have revolutionized our daily life over the last few decades. Morover, if reduced to the
nanometer scale, a wealth of novel properties and physical effects emerged that are partially already exploited technologically. However, some other materials have their own particular specialities that cannot be accomplished by semiconductors alone. By the deliberate realization
of hybrid nanostructures consisting of semiconductors and piezoelectric oxides, or soft matter materials like supported membranes and elastomers we are able to create functional nanosystems that aim towards ‘the best of both worlds’ in such hybrids.
In my talk, I will present a few examples for functional hybrid nanosystems for photonic, electronic and even medical/biological applications. By letting Surface Acoustic Waves interact with these hybrids, novel tunable functionalities can be created that are only possible by combining very different material classes.

Tetraquarks -- Do they matter?

The recently discovered XYZ states in the charmonium region are discussed to be exotic states. The subject of hadron spectroscopy and QCD bound states is introduced. A selection of relevant results obtained by the BESIII experiment are presented. Moreover, unique possibilities of the upcoming PANDA experiment to contribute to solve the XYZ puzzle are discussed.
