The analysis of the system behavior under the effect of the additive noises has been done using a simple model of shear melting. The situation with low intensity of the order parameter noise has been investigated in detail, and time dependence of the order parameter has been calculated. A distinctive feature of the obtained dependence is power-law distribution and self-similarity. The generalized Hurst exponent of the time series has been found within multifractal detrended fluctuation analysis. It is shown that the self-similarity of the time series increases when the noise intensity reduces. 2014-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/153579 Critical relaxation and the combined effects of spatial and temporal boundaries Marcuzzi, M.; Gambassi, A. We revisit here the problem of the collective non-equilibrium dynamics of a classical statistical system at a critical point and in the presence of surfaces. The effects of breaking separately space- and time-translational invariance are well understood, hence we focus here on the emergence of a non-trivial interplay between them. For this purpose, we consider a semi-infinite model with O(n)-symmetry and purely dissipative dynamics which is prepared in a disordered state and then suddenly quenched to its critical temperature. We determine the short-distance behaviour of its response function within a perturbative approach which does not rely on any a priori assumption on the scaling form of this quantity.; Ми знову розглядаємо проблему колективної нерiвноважної динамiки класичної статистичної системи в критичнiй точцi i в присутностi поверхонь. Вплив порушення порiзно просторової i часової трансляцiйної iнварiантностi є добре зрозумiлим, тому тут ми зосереджуємо увагу на виникненнi нетривiальної взаємодiї мiж ними. Для цiєї мети ми розглядаємо напiвбезмежну модель з O(n)-симетрiєю i цiлковито дисипативну динамiку, пiдготовану в невпорядкованому станi, i потiм раптово заморожену до своєї критичної температури. Ми визначаємо поведiнку її функцiї вiдгуку на коротких вiдстанях в межах теорiї збурень, не спираючись на жодне припущення щодо форми цiєї величини. 2014-01-01T00:00:00Z
