WebAbstract. In many materials with a highly anisotropic band structure, electron-phonon interactions lead to a novel type of ground state called the charge-density wave. The … WebJan 1, 1994 · Abstract. Spin-density waves (SDWs) are broken-symmetry ground states of metals, the name referring to the periodic modulation of the spin density with period, λ0 = π kF, determined by the Fermi wave vector kF. The state, originally postulated by Overhauser, has been found in several organic linear-chain compounds.
