Longitudinal SDW order in a quasi-1D Ising-like quantum antiferromagnet

S. Kimura, M. Matsuda, T. Masuda +10

From neutron diffraction measurements on a quasi-1D Ising-like Co $^{2 +}$ spin compound BaCo $_{2}$ V $_{2}$ O $_{8}$ , we observed an appearance of a novel type of incomm…

On calculation of vector spin chirality for zigzag spin chains

Kouichi Okunishi

We calculate the vector spin chirality for $S = 1/2$ zigzag spin chains having U(1) symmetry, using the density matrix renormalization group combined with unitary transformation. We…
