Density
functional theory Density functional theory (DFT) is a quantum mechanical approach to predicting the properties of a system, such as atoms and molecules. It is an important tool in the study of chemical and physical processes. DFT uses a mathematical model to calculate the energy of a system based on the density of its electrons. This allows scientists to understand the behavior and structure of a system without the need for expensive or time-consuming experimental measurements. Additionally, DFT has been used to understand and optimize the behavior of many materials such as catalysts, semiconductors, and pharmaceutical drugs.
