Retardation effects on intra- and intersubband plasmons in quasi-one-dimensional quantum-well wires

The spectrum of the intra-and intersubband plasmon-polaritons of a quasi-one-dimensional quantum-well wire is investigated. The polarization tensor is treated in detail within the random-phase approximation. The dispersion curves of the collective excitations are calculated and presented in graphica...

Description
Summary:The spectrum of the intra-and intersubband plasmon-polaritons of a quasi-one-dimensional quantum-well wire is investigated. The polarization tensor is treated in detail within the random-phase approximation. The dispersion curves of the collective excitations are calculated and presented in graphical form.
