. The process of nonlinear ionization of a two-dimensional nanostructure with a long-range Coulomb potential by a superposition of constant and alternating electric fields is investigated. In the adiabatic approximation, the ionization probability of a two-dimensional atom is calculated taking the Coulomb correction into account. The dependence of the contribution of the Coulomb field to the ionization rate on the ratio of the strengths of constant and alternating electric fields in the process of multiphoton ionization of an atom is investigated. An analytical expression is obtained for the ionization probability of a two-dimensional atom by a constant electric field, taking the Coulomb correction into account.

. We have performed experiments on the influence of corona discharge plasma on samples of dispersed media with organic components (various types of soils). We have revealed the role of air ionization under the action of the corona discharge, which leads to a change in the electrical conductivity of media and to a change in the chemical properties associated with the oxidation of molecular nitrogen to its mineral forms.

The dynamics of tunneling of Bose-condensed atoms in a double-well trap is studied with allowance for the processes of elastic interatomic interaction in each well and nonlinear pair tunneling through the barrier between the wells. Solutions of the resulting system of nonlinear evolution equations describing nonstationary tunneling show that there are both periodic and aperiodic modes of evolution of the difference between the populations of the wells. The features of the time evolution of the system are determined by the initial population difference, the initial phase difference, and the nonlinearity parameter of the system. The possibility of the existence of quantum self-trapping and phase control of the system dynamics is indicated.
