【 摘 要 】

We study the Holstein polaron in transverse magnetic field using nonperturbational methods. At strong fields and large coupling, we show that the polaron has a Hofstadter spectrum, however, very distorted and of lower symmetry than that of a (heavier) bare particle. For weak magnetic fields, we identify nonperturbational behavior of the Landau levels not previously known.
