A set of programs for computing properties of spin-l/2 Heisenberg lattices is presented. The programs make full use of the spin symmetry inherent in these systems by operating in the fully S, M-adapted spin basis. This considerably reduces dimensions of the Hamiltonian matrices to be diagonalized. P
The uniform electron fluid is the reference model for density functional calculations. Even for this system, many-body perturbation theory, and related methods become questionable when the density parameter r s exceeds unity. Hence, quantum Monte Carlo (QMC) simulation has been almost the only appli
