    Dispersive nonlinearity and bistability of polar media

    The nonlinear optical response of polar materials (ionic crystals and polar semiconductors) is studied. Within the generalized Born-Huang theory, the nonlinear response of a system is found to exhibit a charac...

    Discrete levels in the continuum and tunneling

    We investigate electron localization and tunneling in a quasi-one-dimensional nanochannel with two attracting impurities. We solve the one-electron problem for a short-range interaction with the impurity and o...

    Nonlinear anomalies of conducting media with conical microconstrictions

    An investigation is made of the divergence of the higher moments of the field in conducting structures with conical singular regions. Calculations are made of the critical values of the parameters which determ...

    Lithium isotope separation on an ion exchange resin having azacrown ether as an anchor group

    A study on the separation of lithium isotopes was carried out with an ion exchange resin having 1,7,13-trioxa-4,10,16-triazacyclooctadecane (N3O3) as an anchor group. The lighter isotope,6Li concentrated in the r...
