| الوصف: | We investigate heavy-hole--light-hole mixing in quasi-two-dimensional semiconducting structures. We propose and analyze several measures that characterize the mixing quantitatively in Ge, Si, and GaAs. We find that a mixing that is `weak' when considering the light-hole content can be `strong' when considering the induced spin-orbit interactions (SOIs). We identify two different types of hole-Hamiltonian terms concerning mixing. The first type changes the direction of the pure spinors, without admixing light-hole components. It is efficient for Rabi driving the heavy-hole spin. The second type induces mixing and changes the eigenvalues of the $g$ tensor. We restrict ourselves to the zone center, what leads to a simple description, analytical results, and physical insights. We show how the model can be used to investigate heavy-hole spin qubit $g$ tensor, dephasing, relaxation, and Rabi frequencies. Comment: 16 pages, 5 figures |
