Abstract
We study the effect of the interaction of electrons confined in one sp atial direction in a parabolic quantum well with longitudinal optical (LO) phonons in a tilted magnetic field. In detail we analyse the pola ron cyclotron mass, calculated using second-order perturbation theory, in dependence on the magnetic field strength and the tilt angle of th e magnetic field. We find a strong dependence of the cyclotron masses on the tilt angle, corresponding to the two measurable transitions in cyclotron resonance experiments.
