Abstract: The interaction between the quantum states of two aluminum superconductingrings forming an 8-shape circular-asymmetric microstructure was examined undera threading magnetic flux and bias by an alternating current without a dccomponent. Quantum oscillations of the rectified dc voltage VdcB as afunction of magnetic field were measured in the 8-shape microstructure atvarious bias ac currents and temperatures close to critical. Fourier andwavelet analyses of VdcB functions revealed the presence of variouscombination frequencies in addition to two ring fundamental frequencies, whichsuggests the interaction in the structure. Deviation of the VdcB functionfrom oddness with respect to the magnetic field direction was found for thefirst time.
