Weak coupling limit for the ground state energy of the 2D Fermi polaron
David Mitrouskas
We analyze the ground state energy for N fermions in a two-dimensional box interacting with an impurity particle via two-body point interactions. We allow for mass ratios M > 1.225…
Landau-Pekar equations and quantum fluctuations for the dynamics of a strongly coupled polaron
Nikolai Leopold, David Mitrouskas, Simone Rademacher +2
We consider the Fröhlich Hamiltonian with large coupling constant . For initial data of Pekar product form with coherent phonon field and with the electron minimizing the corres…
A note on the Fröhlich dynamics in the strong coupling limit
David Mitrouskas
We revise a previous result about the Fröhlich dynamics in the strong coupling limit obtained in [Gri17]. In the latter it was shown that the Fröhlich time evolution applied to the…
Derivation of the Landau-Pekar equations in a many-body mean-field limit
Nikolai Leopold, David Mitrouskas, Robert Seiringer
We consider the Fröhlich Hamiltonian in a mean-field limit where many bosonic particles weakly couple to the quantized phonon field. For large particle number and suitably small co…
