Abstract 



In this presentation three recent contributions to the theory of continuum (or "Frohlich") polarons are reviewed. (i) Using a generalization of the JensenFeymnan variational principle within the pathintegral formalism for identical particles, the groundstate energy of a confined Npolaron system is studied as a function of N and of the electronphonon coupling strength. (ii) A theoretical investigation of the optical properties of stacked quantum dots is presented, which is based on the nonadiabatic approach. (iii) Cyclotronresonance (CR) spectra of a gas of interacting polarons in a GaAs/AlAs quantum well are theoretically investigated taking into account the magnetoplasmonphonon mixing and the band nonparabolicity. The theory explains that, for a highdensity polaron gas, anticrossing of the CR spectra occurs near the GaAs TOphonon frequency rather than near the GaAs LOfrequency in a good agreement with experimental data.
