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. WebThe ordering wavevector is in A and B and in C and D. The black arrows in Fig. 2B are approximately the ordering wavevectors. (E) The energy gap of CDW produced by the …

Webthe charge order at a wavevector. K =1 = 4 is observed, and we consider it signi cant that this valueemerges nat-urally from our theory. Our large-N. theory only found states in which the ordering wavevector. K. was quantized at the rational plateaus in Fig. 2. However, for smaller. N. we expect that irrational, incommensurate, values of. K ... 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. chiropractic live webinars
