Spin instabilities in coupled semiconductor quantum wells
RJ Radtke, PI Tamborenea, SD Sarma - Physical Review B, 1996 - APS
We study the magnetic phases of two coupled two-dimensional electron gases in order to
determine under what circumstances these phases may occur in real semiconductor
quantum wells, and what the experimental properties of the broken-symmetry ground states
may be. Within the local-density approximation to time-dependent density-functional theory
(DFT), we find a phase transition signaled by the vanishing of the intersubband spin-density
excitations at low but accessible (∼ 10 10–10 11 cm− 2) electron densities. Through a self …
