It involves releasing specific orders to … WebDec 21, 2012 · The antiferromagnetic ordering wavevector is K = (π,π), and →ϕq represents the electron spin density at the wavevector K + q; we will also refer to the antiferromagnetic order as spin density wave (SDW) order. We can thus write the electron part of the Hamiltonian as. H = ∑ k εkc † k ck + λ∑ k,qc † k + K + q(→s ⋅ →ϕq)ck.

WebIf the magnetic ordering wavevector is non-integer, the dispersion is calculated using a coordinate system rotating from unit cell to unit cell. In this case the spin Hamiltonian has to fulfill this extra rotational symmetry which is not checked programatically. Some of the code of the function can run faster if mex files are used. Webcharge order (CO) occurring in the CuO 2 planes. Furthermore, the gradual dependence of the peak intensity on the out-of-plane component of the wavevector Q⊥ is similar to observations in YBCO (7) and indicative of short coherence along the c axis. Figure 1C shows the temperature evolu-tion of the CO peak in REXS: There is an onset temperature T

In this case the … WebApr 1, 2008 · Near the ordering wavevector the vertex is linear in momentum: Γ ↑ ↓ (k, q) ∝ q, where q is the deviation from the AF ordering wavevector Q. (See e.g., Ref. [8].) The form of this linear-momentum suppression factor survives beyond the mean-field treatment of the conduction electron band, as dictated by Adler's Theorem.
WebIn these models, the CDW wavevector is determined by competition between the CDW’s intrinsic ordering wavevector and coupling between the CDW and another degree of freedom, such as the SDW. The low-temperature wavevector may consequently not reflect the formation mechanism for these phases.
