 However, whereas BOMD treats the electronic structure problem within the time-"independent" Schrödinger equation, CPMD explicitly includes the electrons as active degrees of freedom, via (fictitious) dynamical variables.The software is a parallelized plane wave / pseudopotential implementation of density functional theory, particularly designed for "ab initio" molecular dynamics.The Car–Parrinello method is a type of molecular dynamics, usually employing periodic boundary conditions, planewave basis sets, and density functional theory, proposed by Roberto Car and Michele Parrinello in 1985, who were subsequently awarded the Dirac Medal by ICTP in 2009.
