quantum perturbation theory meaning in Hindi

Examples

1. The interaction rates are reviewed in and includes quantum perturbation theory and MD.
2. The theory is however only an approximation which assumes that the interactions can be treated independently, the theory must also be adjusted to take into account quantum perturbation theory.
3. In physics, particularly in quantum perturbation theory, the " "'matrix element "'" refers to the linear operator of a modified Hamiltonian using Dirac notation.
4. To calculate the lifetime of a neutron in a state n according to the usual Quantum perturbation theory, the above matrix elements must be summed over all unoccupied electron and neutrino states.
5. In quantum perturbation theory, it is sometimes said that the contribution of one-loop and multi-loop Feynman diagrams to elementary particle propagators are the contribution of vacuum fluctuations, or the zero-point energy to the particle masses.
