Coherent control of intersubband optical bistability in quantum wells
H. O. Wijewardane, C. A. Ullrich
We present a study of the nonlinear intersubband (ISB) response of conduction electrons in a GaAs/AlGaAs quantum well to strong THz radiation, using a density-matrix approach combi…

Anisotropic splitting of intersubband spin plasmons in quantum wells with bulk and structural inversion asymmetry
C. A. Ullrich, M. E. Flatte
In semiconductor heterostructures, bulk and structural inversion asymmetry and spin-orbit coupling induce a k-dependent spin splitting of valence and conduction subbands, which can…
