Semiclassical superoscillations: interference, evanescence, post-WKB
The concept of superoscillations is extended beyond bandlimited functions, to include monochromatic waves in space-varying media, such as wavefunctions representing quantum particles in non-constant potentials. ‘Semiclassical superoscillations’ are defined as places where the phase gradient (local w...
