WebJastrow-Slater wave function The QMC method is thought to be promising for the treatment of dynamical and static eiectron correiation effects with the compact functional … In quantum physics, a wave function is a mathematical description of the quantum state of an isolated quantum system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively).
