Chirality, charge and spin-density wave instabilities of a two-dimensional electron gas in the presence of Rashba spin-orbit coupling

摘要: We show that a result equivalent to Overhauser’s famous Hartree-Fock instability theorem can be established for the case of two-dimensional electron gas in presence Rashba spin-obit coupling. In this it is spatially homogeneous paramagnetic chiral ground state shown differentially unstable with respect certain class distortions spin-density-wave and charge-density-wave type. The holds all densities. Basic properties these inhomogeneous states are analyzed.
