Transitions from low-density state towards high-density state in stochastic bistable plasma-condensate systems
In this article we study transitions from low-density states towards high-density states in bistable plasmacondensate systems. We take into account an anisotropy in transference of adatoms between neighbour layers induced by the electric field near substrate. We derive the generalized one-layer mod...

irk-123456789-1574632019-06-21T01:28:35Z Transitions from low-density state towards high-density state in stochastic bistable plasma-condensate systems Dvornichenko, A.V. Kharchenko, V.O. Kharchenko, D.O. In this article we study transitions from low-density states towards high-density states in bistable plasmacondensate systems. We take into account an anisotropy in transference of adatoms between neighbour layers induced by the electric field near substrate. We derive the generalized one-layer model by assuming that the strength of the electric field is subjected to both periodic oscillations and multiplicative fluctuations. By studying the homogeneous system we discuss the corresponding mean passage time. In the limit of weak fluctuations, we show the optimization of the mean passage time with variation in the frequency of periodic driving in the non-adiabatic limit. Noise induced effects corresponding to asynchronization and acceleration in the transition dynamics are studied in detail. У цiй статтi нами дослiджено переходи вiд стану з низькою густиною адсорбату до стану з його високою концентрацiєю в бiстабiльних системах плазма-конденсат. При цьому враховується анiзотропiя у переходах адатомiв мiж сусiднiми шарами, що спричинена дiєю електричного поля поблизу поверхнi. В рамках узагальненої одношарової моделi дослiджуються ефекти, пов’язанi з перiодичними коливаннями та флуктуацiями напруженостi електричного поля. При дослiдженнi однорiдної системи встановлено особливостi зовнiшнього впливу на середнiй час переходу вiд стану з низькою густиною адсорбату до стану з високою його концентрацiєю. В границi слабких флуктуацiй продемонстровано процес оптимiзацiй середнього часу переходу при змiнi частоти перiодичного керуючого поля.

| description |
In this article we study transitions from low-density states towards high-density states in bistable plasmacondensate systems. We take into account an anisotropy in transference of adatoms between neighbour layers
induced by the electric field near substrate. We derive the generalized one-layer model by assuming that the
strength of the electric field is subjected to both periodic oscillations and multiplicative fluctuations. By studying
the homogeneous system we discuss the corresponding mean passage time. In the limit of weak fluctuations,
we show the optimization of the mean passage time with variation in the frequency of periodic driving in the
non-adiabatic limit. Noise induced effects corresponding to asynchronization and acceleration in the transition
dynamics are studied in detail. |
