Manifestation of the magnetic depopulation of one-dimensional subbands in the optical absorption of acoustic magnetoplasmons in side-gated quantum wires

C. Steinebach, T. Kurth, D. Heitmann +1

We have investigated experimentally and theoretically the far-infrared (FIR) absorption of gated, deep-mesa-etched GaAs/Al${}_x$Ga${}_{1-x}$As quantum wires. To overcome Kohn's theorem…
