We describe how starting from a type of nearest-neighbour localized wavefunction cluster expansion one may conveniently build up a locally correlated orthonormal 'many-body' basis for a linear-chain system. The initial correlated cluster expansion approximant to the ground state plays the role of a 'vacuum' while the other members of the basis are single or multiple excitations above this. The scheme is illustrated for the case of two states per site, in application to the linear-chain Heisenberg model. © 1996 IOP Publishing Ltd.
