Three–Body Configuration Space Calculations with Hard Core Potentials
We present a mathematically rigorous method suitable for solving three-body bound state and scattering problems when the inter–particle interaction is of a hard–core nature. The proposed method is a variant of the Boundary Condition Model and it has been employed to calculate the binding energies for a system consisting of three 4He atoms. Two realistic He–He interactions of Aziz and collaborat...

متن کاملScreened KKR with hard-core potentials
We developed a self-consistent screened-Korringa± Kohn± Rostoker (KKR) method in an ab initio tight-binding formulation. The reduction in numerical e ort in comparison with that required for the standard KKR method is achieved by the choice of a suitable reference system. Following the idea of Zeller et al. (1995, Phys. Rev. B, 52, 8807), reference systems with repulsive mu n-tin potentials o...
متن کاملComparison of Hard-Core and Soft-Core Potentials for Modelling Flocking in Free Space
An investigation into the properties of a two dimensional (2D+1) system of self propelled particles (known as boids) in free space is conducted using a Lagrangian Individual-Based Model. A potential, associated with each boid is specified and a Lagrangian is subsequently derived in order to obtain the equations of motion for each particle in the flock. The Morse potential and the Lennard-Jones ...
متن کاملBoundary conditions for three-body scattering in configuration space.
The asymptotic behavior of three-body scattering wave functions in configuration space is studied by considering a model equation that has the same asymptotic form as the Faddeev equations. Boundary conditions for the wave function are derived, and their validity is verified by numerical calculations. It is shown that these boundary conditions for the partial differential equation can be used t...
