We calculate the persistent current in a multichannel semiconductor ring with strongly correlated electrons when they form a Wigner crystal (WC). Pinning this crystal with a smooth gate potential leads to the suppression of the amplitude of the Aharonov-Bohm oscillations and to the fractionalization

Coupling-current losses in a multifilamentary superconducting wire with a normal metal core were calculated for the case of transverse magnetic fields. The results showed that the dependence of the coupling~turrent loss of such a wire on the rate of field variation is markedly different from that of
The performance of an energy sensitive, niobium superconducting tunnel junction (STJ) detector is investigated by measuring the pulse height produced by impacting molecular and atomic ions at different kinetic energies. Ions are produced by laser desorption and matrix-assisted laser desorption in a
Adequate analyses of canonical molecular orbitals (CMOs) can provide rather detailed information on the importance of different Ο-Fermi contact (FC) coupling pathways (FC term transmitted through the Ο-skeleton). Knowledge of the spatial distribution of CMOs is obtained by expanding them in terms of
