摘要：

We report temperature effects in the Landau damping of the acoustic plasmon mode in a double-quantum-well system. Its dispersion has been measured using Raman spectroscopy and modeled within the random-phase approximation (RPA). The Landau damping of the acoustic plasmon has also been modeled within the RPA using a O-K Hubbard correction, with mixed success. This points to the need for further theoretical work on local-field corrections at higher temperatures, but shows the value of the study of the temperature dependence of Landau damping as a probe of many-body effects.
