Electrons in quantum corrals show acoustic-style resonance and antiresonance

Evidence

All matter is really wavelike if you look close enough. The electrons hopping off the tiny needle (the source) are like sound waves traveling along the surface, bouncing off obstacles, (atoms), and reflecting back to the source. Depending on the location of the obstacles, and the wavelength of the electrons (which is controlled by the applied voltage), there may be constructive (resonant) or destructive (antiresonant) interference between the amplitude freshly supplied by the needle and the amplitude that has returned from one or more reflections off iron atoms or structures made from them. — Eric J.
