Ordering wave vector
WebDec 22, 2024 · Within the CuO planes, the distortions involve a periodic modulation of the Cu-Cu spacing along the direction of the ordering wave vector. The charge ordering within the copper-oxygen layer induces an out-of-plane breathing modulation of the surrounding lanthanum layers, which leads to a related distortion on the adjacent copper-oxygen layer. Webfluctuating SDW order parameter near wave vector Q is thus ~S QðxÞ¼S0e iθðxÞN~ðxÞ: ð4Þ The corresponding fluctuating CDW order parameter is ρ 22Q ¼ ρ 0 Q e 2iθ: ð5Þ It is useful to formulate discussions offluctuations in terms of the two separate fields b ≡eiθ and N~. Both the SDW order parameter S~ Q ∼bN~ and the CDW order ...
