UNPRECEDENTED POSSIBILITY OF DISCRETE SCATTERING STATES AND THEIR CONTROL

Abstract

The discrete states of unlimited wave motion, "antipodes" of Anderson's localization [Phys. Rev.109, 1492–1505 (1958)] ("continuum of bound states"), are presented. This newly mentioned and an unexpected kind of spectrum appeared to be attainable via a multiple combination of the remarkable phenomenon of resonance tunneling. It was found that this unusual spectral situation takes place for a quantum system of infinite irregularly distributed resonance tunneling potential traps. Generalization of this instructive phenomenon to periodic, multi-channel structures is considered.
