Wichtige Information:

Important information:

Wegen des Coronavirus-Ausbruchs und der Absage aller Lehrveranstultangen mit physischer Präsenz an der Uni Wien und der TU Wien, findet auch das Lunch-Seminar vorerst nicht statt.

Due to the coronavirus outbreak and the cancellation of all courses with physical attendance at the University of Vienna and the TU Wien, the Lunch Seminar will not take place until further notice.

Idea:

Wie auf vielen Universitäten praktiziert wollen wir ein Lunch-Seminar etablieren, das aktuelle Themen der Theoretischen Physik, die von DiplomandInnen, DoktorandInnen und PostDocs behandelt werden, aufgreift.

Das Niveau soll so gewählt werden, dass jeder Student und jede Studentin am Beginn des Masterstudiums dem Vortrag folgen kann. BachelorstudentInnen können besonders von dem Seminar profitieren, da es ihnen ermöglicht einen Eindruck in die Forschungsarbeit beider Universitäten zu erhalten. Die Vortragenden werden dabei auch ermutigt darüber zu sprechen, warum sie ein gewisses Forschungsgebiet gewählt haben. Dabei dürfen durchaus offene Fragen und Probleme behandelt werden und es ist nicht notwendig einen Vortrag über eine "perfekte", abgeschlossene Arbeit zu halten.

Damit es zu keinem "Zeitverlust" kommt, wird Mittagessen (Pizza) gratis zur Verfügung gestellt.

We want to establish a lunch seminar as practiced at other universities. The focus is on recent theoretical research done by Master students, PhDs and PostDocs.

The seminar is designed for graduate students but should also be comprehensible to advanced undergraduate students. Undergraduate students are particularly encouraged to attend so that they receive an overview of research activities conducted at both universities. Speakers are also encouraged to focus on their motivation for choosing their particular topic and to present open questions.

In order to avoid any "loss of time" we provide a free lunch (pizza).

Scale-dependent black hole solutions.

In this talk, I will review the main features of scale-dependent gravity applied to black hole physics. In particular, starting from the effective average action, I promote the classical coupling to scale-dependent one. After that, I derive the effective Einstein's field equations and compute the new solution in the scale-dependent scenario for certain well-known black hole classical solutions. Finally, some thermodynamic properties are analyzed in detail.

Path Integral for Relativistic Worldlines

I present a stepwise construction of the path integral over relativistic orbits in Euclidean spacetime. It is shown that the apparent problems of this path integral, like the breakdown of the naive Chapman-Kolmogorov relation, can be solved by a careful analysis of the overcounting associated with local and global symmetries. Based on this, the direct calculation of the quantum propagator of the relativistic point particle in the path integral formulation results from a simple and purely geometric construction.

The result can also be reproduced with the corresponding Fadeev-Popov determinant and with a hidden constraint within the Hamiltonian action formulation.

Angular distributions in multi-photon double ionization

In this talk angular distributions of helium electrons ionized by ultra-short, intense laser fields will be presented. By systematically increasing the laser wavelength and thus the number of photons necessary to overcome the double ionization potential, connections are established between the observed angular patterns and the number of absorbed photons. Further, the effect of the laser polarization on the angular distributions will be presented together with the observed circular dichroism.
