Projection Approach

We apply the theory of magneto-optical transitions, introduced earlier by utilizing a many-body projection technique, on a system of electrons scattered by piezoelectric phonons in GaAs; the temperature dependence of the cyclotron resonance linewidth is investigated. It is shown that the width in the quantum limit increases with the temperature.PACS Nos.: 70.00--79.90

Excitonic Effects

The paper sets out the role of electronic coherence in the strong temperature dependence of the intensity of Raman scattering from two atom diameter HgTe nanowires. It argues the behavior is likely common in extreme nanowires, and possibly due to excitonic effects.
