quasi-harmonic approximation
1Wigner quasi-probability distribution — See also Wigner distribution, a disambiguation page. The Wigner quasi probability distribution (also called the Wigner function or the Wigner Ville distribution) is a special type of quasi probability distribution. It was introduced by Eugene… …
2Second harmonic generation — (SHG; also called frequency doubling) is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively combined to form new photons with twice the energy, and therefore twice the frequency and half the… …
