On the global minimum of the energy-momentum relation for the polaron
Jonas Lampart, David Mitrouskas, Krzysztof Myśliwy
For the Fröhlich model of the large polaron, we prove that the ground state energy as a function of the total momentum has a unique global minimum at momentum zero. This implies th…
Optimal parabolic upper bound for the energy-momentum relation of a strongly coupled polaron
David Mitrouskas, Krzysztof Myśliwy, Robert Seiringer
We consider the large polaron described by the Fröhlich Hamiltonian and study its energy-momentum relation defined as the lowest possible energy as a function of the total momentum…
Polaron models with regular interactions at strong coupling
Krzysztof Myśliwy, Robert Seiringer
We study a class of polaron-type Hamiltonians with sufficiently regular form factor in the interaction term. We investigate the strong-coupling limit of the model, and prove suitab…
Microscopic derivation of the Fröhlich Hamiltonian for the Bose polaron in the mean-field limit
Krzysztof Myśliwy, Robert Seiringer
We consider the quantum mechanical many-body problem of a single impurity particle immersed in a weakly interacting Bose gas. The impurity interacts with the bosons via a two-body…
