TRR 181 Seminar "Wave attractors"
The TRR 181 seminar is held every two weeks in the semester and as announced during semester break. The locations of the seminar changes between the three TRR181 locations, but is broadcastet online for all members of the TRR.
The TRR 181 seminar is held by Prof. Leo Maas (Utrecht University and Royal Netherlands Institute for Sea Research) on
Wave attractors
at Universität Hamburg, on December 1 at 10 am, Bundesstr. 53, Room 24 (ground floor).
Abstract
In dynamical systems, an attractor is a subset of phase space towards which a system evolves, regardless of its initial conditions. In geophysical and astrophysical fluids, rotation and density stratification create anisotropic equilibria. Perturbations to these equilibrium states are present as internal waves. Internal waves, reflecting at boundaries that are sloping with respect to the direction of gravity or rotation axis, are focused, and propagate towards a subset of real space at so?called wave attractors. Theory and experiments elucidate the nature and ubiquity of wave attractors.
