Microscopic derivation of the Fröhlich Hamiltonian for the Bose polaron in the mean-field limit

MATHPHYS ANALYSIS SEMINAR

Date: November 26, 2020 | 4:15 pm – 5:15 pm
Speaker: Krzysztof Mysliwy, IST Austria
Location: Online via Zoom

We consider the quantum mechanical many-body problem of a single impurity particleimmersed in a weakly interacting Bose gas. The impurity interacts with the bosons via atwo-body potential. We study the Hamiltonian of this systemin the mean-field limit andrigorously show that, at low energies, the problem is well described by the Fröhlich polaron model. In collaboration with Robert Seiringer.
