A illustration quantifies the interactions between two distinct objects or entities inside an outlined system. It’s structured as an array, with components defining the coupling energy or relationship traits. For example, contemplate a system of two atoms interacting by way of a possible. The array would comprise components describing the energy of their interplay at numerous distances.
Such a formulation is key in fields like quantum mechanics, molecular dynamics, and community evaluation. Its significance lies in simplifying advanced many-body issues by specializing in pairwise relationships. Early developments in quantum chemistry closely relied on this strategy to approximate digital interactions, enabling calculations of molecular properties.
