We study theoretically the collective electronic excitations of quasi-one-dimensional
cylindrical quantum-well wires, the intrasubband and intersubband plasmons in the random …

The exchange and correlation effects of a quasi-one-dimensional electron gas are
investigated by using the self-consistent-field approximation theory proposed by Singwi …

The collective electronic excitations in quasi‐one‐dimensional cylindrical quantum‐well
wires are studied theoretically. Using a two‐subband model the dispersion curves of the …

We have evaluated within the random-phase approximation the density-response function of
laterally modulated two-dimensional electron systems, examining both single-particle and …

In the framework of the current-response scheme we develop the theory of magneto-optical
absorption of the quasi-one-dimensional electron gas synthesized in semiconductor …

The effect of cross-sectional geometry on both the intrasubband plasmon and intersubband
plasmon of a quantum wire is investigated within a two-subband RPA scheme. Exact …

We consider the two-dimensional electron gas confined laterally to a narrow channel by a
harmonic potential. As the Zeeman splitting matches the intersubband separation, the …

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 …

Coulomb interactions in a dilute one-dimensional (1D) electron system in high quality
cleaved-edge overgrown GaAs quantum wires are probed by optics experiments. Intra …

Cleaved-edge overgrown semiconductor quantum wires containing a one-dimensional
electron gas with few occupied subbands are probed by optical experiments. Inter-sub-band …
