The source particle method (SPM) due to Percus and Verlet of obtaining the single particle density, and the pair and triplet distribution functions of classical fluids (as well as in the variational theory of Bose liquids) is studied. Generalizations

We study a variational multiparticle correlation theory for the ground state of inhomogeneous Bose fluids at zerotemperature. The ground state wave function of a many-boson system is written as a generalized Jastrow–Feenberg function including mult

We consider the calculation of the excess entropy in the grand canonical ensemble and redevelop a systematic expansion in terms of the multiparticle correlation functions. The exact expansion for the entropy is written as two series of functions, one

The properties of two-dimensional liquid 4He film at T = 0 are calculated with HNC-optimization. The effect of elementary diagrams is taken into account with Pade-technique. The agreement is good with Monte Carlo results. Utilizing the HNC-solution f

A method for numerical calculation of integrals containing Bessel functions of integer or integer plus one-half order is described. The calculation involves first a one-dimensional Fourier sine or cosine transform followed by evaluation of the coeffi

We apply the hypernetted chain theory (HNC) of inhomogeneous systems in the canonical ensemble to derive a new integral equation for the function that corrects the superposition approximation of the triplet distribution function of the homogeneous sy

The anisotropic antiferromagnetic chain at T = 0 is studied using the renormalization group method for the perturbation expansion of the Dyson-Maleev spin wave model in the inverse of the spin 1/S. We show that the momentum shell recursion relations

The effect of elementary diagrams on liquid 4 He at T = 0 are studied by using two different equations, the hypernetted chain (HNC), not containing the three-body radial distribution function and the Born-Bogoliubov-Green-Kirkwood-Yvon (BBGKY) equati
