Resonant transport and giant persistent currents in double-asymmetric rings

Regular Article

Abstract

Occurrence of resonant transport due to Fabry-Perot like effect through cascade double asymmetric rings is proposed. We find that high performance reflectors with wide bands can be generated by two asymmetrical open rings with an arm ratio of 1/3. At the resonances, giant persistent currents exist in both rings of the system. The resonance energy is variant and dependent on the length of the connected wire. However, the confined space of the system at the resonance is not equal to the integral multiple of a half-wavelength of traditional Fabry-Perot etalons.
