Abstract
Cyclotron resonance of magnetopolarons in a parabolic quantum dot with a strong magnetic field normal to the plane of the quantum dot is investigated theoretically. It is shown that for a strong magnetic field (≫), the cyclotron mass in a parabolic quantum dot is split into two cyclotron masses ( and ). One () is lower than the bare band mass, but increases with increasing effective confinement length of the quantum dot, and approaches that of the two-dimensional case. The other () is greater than the bare band mass and might be a measurable effect for small quantum dots.
