Abstract

Coherent ballistic transport through a circular resonant cavity in a quantum electron waveguide is examined. The circular cavity is weakly coupled to a rectangular channel. The current density in the cavity region is calculated from the solution to the effective-mass Schrödinger equation. Current vortex formation in the cavity and a related increase in probability density in the the cavity occur at certain resonant energies.
