Zero-point energy — is the lowest possible energy that a quantum mechanical physical system may have; it is the energy of its ground state. All quantum mechanical systems undergo fluctuations even in their ground state and have an associated zero point energy, a… … Wikipedia
Diabatic — See also adiabatic process, a concept in thermodynamics A diabatic process is one in which heat transfer takes place, which is the opposite of an adiabatic process.[1] In quantum chemistry, the potential energy surfaces are obtained within the… … Wikipedia
Conical intersection — Ideal Conical Intersection In quantum chemistry, a conical intersection of two potential energy surfaces of the same spatial and spin symmetries is the set of molecular geometry points where the two potential energy surfaces are degenerate… … Wikipedia
Born-Huang approximation — The Born Huang approximation (named after Max Born and Huang Kun) is an approximation closely related to the Born Oppenheimer approximation. It takes into account more nonadiabatic effects in the electronic Hamiltonian than the Born Oppenheimer… … Wikipedia
