In contrast to classical physics, the language of quantum mechanics involves operators and wave functions (or, more generally, density … WebThe quantum effect on the Wigner time-delay and distribution for the polarization scattering in a semiclassical dense plasma is explored. The partial wave analysis is applied for a partially ionized dense plasma to derive the phase shift for the polarization interaction. The Wigner time-delay and the Wigner distribution are derived for the electron–atom …
Webthe distribution functions obtained by the Weyl correspondence [4] are the Wigner functions. Moyal also showed how the time dependence of W and other such functions (which arise from alternative association rules other than Wigner-Weyl but which lead to the same physical results) may be determined without using the Schr¨odinger equation. WebApr 13, 2024 · However, when I tried the Wigner-Ville and Smoothed-Pseudo-Wigner-Ville distribution, its impossible with the same number of samples. Therefore, I tried to reduce the number of samples to 12.000 only, and yet so computationally expensive. I know that the wigner-ville distribution has a better time-frequency resolution tradeoff.
WebJul 17, 2024 · This looks somewhat similar to the way it was introduced in Ville’s original paper.
