Abstract

In this first lecture we study the energy spectrum of Fröhlich polarons in a uniform magnetic field. In the first part (section 1.1 and section 1.2) the constants of the motion for a polaron in a uniform magnetic field are derived and compared with those of a free electron in a uniform magnetic field. The operators describing these constants of the motion satisfy the same algebra in both cases. This implies that the degeneracy of the eigenstates of the electron in a homogeneous magnetic field is not lifted by the Fröhlich interaction. In the second part of this lecture, I briefly review some calculations of the spectrum of a polaron in a magnetic field (section 1.3 and section 1.4).
