: It involves the scattering of electrons at the interface of a superconductor and a material like a Weyl semimetal .
: Researchers have found that for certain energy levels (subgap energies), the probability of this reflection reaches a "perfect" state (1.0 probability), which contributes to universal conductance values. Perfect.rar
In the Super Smash Bros. series, stands for Reverse Aerial Rush . A "perfect" (or frame-perfect) RAR is a high-level technique used to maintain forward momentum while performing a back-air attack. : It involves the scattering of electrons at
