A Tight Binding Monte Carlo Simulation Approach to the Cohesive Energy of Amorphous Metallic Alloys

We present microscopic calculations of the cohesive energy of amorphous metallic alloys. Our method is based on a tight-binding and Monte Carlo simulation approaches to calculate the equilibrium atomic structure. The same model tight-binding Hamiltonian is then used to calculate electronic structure and energy using a Bethe-Cluster approximation.
