Ubiquity of bound states for the strongly coupled polaron
David Mitrouskas, Robert Seiringer
We study the spectrum of the Fröhlich Hamiltonian for the polaron at fixed total momentum. We prove the existence of excited eigenvalues between the ground state energy and the ess…
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…
