Perdew

Perdew is a surname. Notable individuals with this name include John P. Perdew, an American theoretical physicist and chemist whose work has significantly influenced density functional theory (DFT). In this field, Perdew co-developed several exchange-correlation functionals that are widely used in electronic structure calculations. Among these are the PW91 and the PBE functionals. The PBE functional, named after Perdew, Burke, and Ernzerhof, is a generalized gradient approximation that balances accuracy and computational efficiency and has become one of the most widely cited functionals in chemistry and condensed matter physics. Perdew’s contributions have shaped how researchers model the electronic structure of atoms, molecules, and solids, and his work continues to underpin a broad range of computational methods in physics, chemistry, and materials science.
