Abstract
Absorption of a surface acoustic wave by a quantum-ring array occupied by one or two electrons is considered. Dependences of the absorption coefficient on the magnetic flux through the quantum ring and the acoustic-wave frequency with allowance made for the Coulomb interaction between electrons are calculated. It is shown that the absorption coefficient is an oscillatory function of the magnetic flux with a period equal to the magnetic-flux quantum.
