Spin-orbit coupling-induced anisotropies of plasmon dynamics are investigated in two-dimensional semiconductor
structures. The interplay of the linear Bychkov-Rashba and Dresselhaus spin-orbit interactions
drastically affects the plasmon spectrum: the dynamical structure factor exhibits variations over several decades,
prohibiting plasmon propagation in specific directions. While this plasmon ...
