Kolloquium

Thema:

Sehen wie zum ersten Mal - zur Physik des Alltäglichen

Datum:

03.12.18

Uhrzeit:

16:15

Ort:

H6

Vortragender:

Prof. Dr. Hans Joachim Schlichting

Universitaet Muenster

Inhalt:

Anhand von ganz unterschiedlichen Beispielen wird dargelegt, dass das Alltägliche und Vertraute zu einer neuen Realität werden kann, wenn man lernt, es unter einer physikalischen Perspektive zu sehen. Auf diese Weise kann erfahren werden, dass die Physik nicht nur das zeigt, was wir noch nicht kennen, sondern auch das, was wir kennen, wie wir es noch nicht kennen. Neben einer Bereicherung alltäglicher Wahrnehmungen werden dadurch für Lernende Wiederbegegnungen mit physikalischen Sachverhalten ermöglicht, die aus lerntheoretischer Sicht zur Förderung und Nachhaltigkeit des Gelernten beitragen können.

The stringy dimension of physics: a perspective from philosophy of science

Inhalt:

The practice of physics is shaped by experiences and expectations. Physicists and philosophers of science alike are tempted to evaluate scientific achievements by relating them to successfully tested predictions. However, some contemporary research programs at the physical frontiers refuse to be rated based on their power to predict testable phenomena. Without the crucial link to the natural world other criteria of evaluation must be considered. Recently, a shift of strategies for theory assessment was proposed as an explanation to why large numbers of physicists are attracted by string theoretical research. However, historical accounts pointed out years ago shifting practices of fundamental physics that dislocate the balanced system of experiment, theory and mathematics that once established physics as a ‘hard science’.

Symmetry Transition from GUE to chGUE protecting Chirality

Inhalt:

Symmetry transitions of systems have been always of particular interest in physics. There are only few real systems, that are pure and ideal yielding the desired results predicted by simplified, analytically feasible models. This is also the case for the spectral statistics of linear operators corresponding to such realistic systems, which are usually described by random matrices. Especially the global symmetries can be well-captured by random matrices, since the local spectral statistics on the level of the mean level spacing is extremly sensitive to these symmetries. Therefore, the question arises what the statistics would look like when a symmetry transition takes place to compare these results efficiently with physical measurements. Exactly this has been the goal of my joint work with Takuya Kanazawa when we studied an interpolation between the Gaussian unitary ensemble (GUE) and the chiral Gaussian unitary ensemble (chGUE) while protecting the chirality of the matrix. This transition is motivated by several QCD applications. Particularly the protection of the chirality leads to surprising effects. I am going to report on these results which comprise finite matrix size as well as the limit of large matrix dimensions.
