Fock space — The Fock space is an algebraic system (Hilbert space) used in quantum mechanics to describe quantum states with a variable or unknown number of particles. It is named for V. A. Fock.Technically, the Fock space is the Hilbert space made from the… … Wikipedia
Fock state — A Fock state (also known as a number state), in quantum mechanics, is any element of a Fock space with a well defined number of particles (or quanta). These states are named after the Soviet physicist, V. A. Fock. Contents 1 Definition 2 Energy… … Wikipedia
Basis set (chemistry) — A basis set in chemistry is a set of functions used to create the molecular orbitals, which are expanded as a linear combination of such functions with the weights or coefficients to be determined. Usually these functions are atomic orbitals, in… … Wikipedia
Fock matrix — In quantum mechanics, the Fock matrix is a matrix approximating the single electron energy operator of a given quantum system in a given set of basis vectors.It is most often formed in computational chemistry when attempting to solve the Roothaan … Wikipedia
Hartree-Fock — In computational physics and computational chemistry, the Hartree Fock (HF) method is an approximate method for the determination of the ground state wavefunction and ground state energy of a quantum many body system.The Hartree Fock method… … Wikipedia
Post-Hartree-Fock — In computational chemistry, Post Hartree Fock methods are the set of methods developed to improve on the Hartree Fock (HF), or self consistent field (SCF) method. They add electron correlation which is a more accurate way of including the… … Wikipedia
Unrestricted Hartree-Fock — (UHF) theory is the most common molecular orbital method for open shell molecules where the number of electrons of each spin are not equal. While restricted Hartree Fock theory uses a single molecular orbital twice, once multiplied by the α spin… … Wikipedia
Restricted Open-shell Hartree-Fock — (ROHF) is a variant of Hartree Fock theory for open shell molecules. It uses doubly occupied molecular orbitals as far as possible and then singly occupied orbitals for the unpaired electrons. This is the simple picture for open shell molecules… … Wikipedia
Linear combination of atomic orbitals molecular orbital method — A linear combination of atomic orbitals or LCAO is a quantum superposition of atomic orbitals and a technique for calculating molecular orbitals in quantum chemistry [Huheey, James.
