We investigated the properties of the spin-1/2 ferromagnetic-antiferromagnetic-antiferromagnetic alternating Heisenberg chain using the spin-wave theory. The spin-wave excitation spectra, the sublattice magnetizations and the local bond energies of the model are calculated to be compared with the co

We extend our own previous applications of the microscopic coupled-cluster method (CCM) to quantum antiferromagnets. In particular, we carry out a systematic calculation involving high-order multispin correlations for the spin-f anisotropic Heisenberg models on the one-dimensional chain and the two-

The orthogonally spin-adapted (OSA) state-universal coupled-cluster method involving singly and doubly excited clusters (CCSD) and the recently proposed OSA open-shell state-specific CCSD method are applied to the problem of singlet-triplet separation in methylene. Both double zeta (DZ) and DZ plus
