What Does ECA Stand For?
ECA stands for Equivalent Core Approximation
Equivalent Core Approximation (ECA) refers to a computational method used in various fields such as quantum chemistry and materials science. It simplifies complex systems by approximating the effects of a detailed core region with a simplified model, allowing for more efficient calculations while maintaining accuracy in describing the system's behavior. ECA is particularly useful in evaluating electronic interactions and properties in large molecular and solid-state systems, facilitating faster simulations and analyses.
