Scattering of scalar waves by many small particles
Alexander G. Ramm
Formulas are derived for solutions of many-body wave scattering problems by small particles in the case of acoustically soft, hard, and impedance particles embedded in an inhomogen…

Helium- and Lithium-like ionic sequences: Critical charges
N. L. Guevara, A. V. Turbiner
In non-relativistic quantum mechanics we study the Coulomb systems of infinitely massive center of charge Z and two-three electrons: and . It is shown that in…

Electromagnetic wave scattering by a thin layer in which many small particles are embedded
A. G. Ramm
Scattering of electromagnetic (EM) waves by many small particles (bodies), embedded in a thin layer, is studied. Physical properties of the particles are described by their boundar…
