Решения полученной системы нелинейных эволюционных уравнений, описывающих нестационарное туннелирование, показывают, что существуют как периодический, так и апериодический режимы эволюции разности населенностей ям. Особенности временной эволюции системы определяются начальной разностью населенностей, начальной разностью фаз и параметром нелинейности системы. Указано на возможность существования явления квантового самозахвата и фазового управления динамикой системы.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бозе-эйнштейновская конденсация</kwd><kwd>квантовый самозахват</kwd><kwd>нелинейное туннелирование</kwd><kwd>фазовый контроль</kwd><kwd>периодический режим</kwd><kwd>апериодический режим</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bose-Einstein condensation</kwd><kwd>quantum self-trapping</kwd><kwd>nonlinear tunneling</kwd><kwd>phase control</kwd><kwd>periodic mode</kwd><kwd>aperiodic mode</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Leggett A.
