Ключевые слова (''Своб.индексиров.''): noise-induced synchronization --spatial interaction--nonequilibrium phase transitions
Аннотация: Noise-induced synchronization, which resembles the critical phase transition upon attaining a rather large intensity of white noise, is manifested in a spatially distributed system with the 1/f spectrum of power, which describes nonequilibrium phase transitions. In this case, the spatial interaction in the system is important.

Ключевые слова (''Своб.индексиров.''): stochastic equations--stochastic resonance
Аннотация: The system of two nonlinear stochastic equations simulating 1/f fluctuations during the interaction of nonequilibrium phase transitions in the presence of an external periodic action has been studied by numerical methods. It is shown that in the system there appears stochastic resonance, which leads to an amplification of the output periodic signal under the action of noise. To a random process with a 1/f power spectrum corresponds the maximum Gibbs-Shannon informational entropy. At stochastic resonance the informational entropy is minimum. A new behavior of a two-dimensional system at stochastic resonance has been revealed: at low frequencies of a periodic action with an increased white noise intensity the system trajectories are limited by two mutually perpendicular directions - anisotropic stochastic resonance. With a further increase in the white noise intensity in the system one can observe "ordinary" stochastic resonance, when the increasing intensity of fluctuations in the vicinity of the driving frequency is smeared in the directions

Ключевые слова (''Своб.индексиров.''): harmonic force--low-frequency pulsations--heat-mass transfer
Аннотация: Using the principle of maximum entropy, we investigate the stability of stochastic processes with the 1/f power spectrum in the system of two nonlinear stochastic differential equations when modeling pulsations in crisis and transient heat-mass transfer regimes with intensive phase transitions. An analysis of the stability of the resultant process, which appears upon the interaction of the stochastic process and the 1/f spectrum of external deterministic impact, is performed. Under the action of harmonic force, stable resultant processes are divided into two types depending on the amplitude of the harmonic force. We have experimentally studied the influence of harmonic impact on the stability of pulsations with the 1/f spectrum upon the crisis of water boiling on a heated wire. The results are in qualitative agreement with theoretical estimations

Ключевые слова (''Своб.индексиров.''): random process --1/f spectrum --lorentz spectrum
Аннотация: The stability of the resultant process, which appears upon the interaction of a random process having a 1/f spectrum with a deterministic action, is analyzed using the entropy maximum principle. Under the action of a harmonic force, stable resultant processes are divided into two branches depending on the amplitude of the harmonic force. Due to an exponential relaxation upon an increase in the damping coefficient, the resultant process acquires the Lorentz spectrum without high-energy low-frequency spikes

Ключевые слова (''Своб.индексиров.''): lennard-jones fluid--melting line--metastable state
Аннотация: A molecular dynamics method was used to calculate the pressure p* and the internal energy e* of a liquid and a crystal in stable and metastable states in a system of 2048 particles, which interaction is described by a modified Lennard-Jones potential. For the liquid phase, calculations were performed along 13 isotherms from the range of reduced temperature T* = 0.35-3.0, and for the crystal phase, along 16 isotherms from the range T* =0.1-3.0. The thermal p* = p*(ρ*,T*) and caloric e* = e*(ρ*,T*) equations of state for liquids and crystals have been constructed. The parameters of crystal-liquid phase equilibrium have been determined from the conditions of phases coexistence at positive pressures and in the region of negative pressures, where the coexistent phases are metastable. The spinodal of a stretched liquid has been approximated. It has been found that with a temperature decrease the metastable extension of the melting line meets the spinodal of the liquid phase. The point of their meeting, the endpoint of the melting curve, is the point of termination of crystal-liquid phase equilibrium without the onset of identity of the phases

Аннотация: The interaction of (Br -) iH 2O) 50-i, 0 ≤ i ≤ 6 clusters with oxygen and ozone molecules is investigated by the method of molecular dynamics simulation. The ozone molecules as well as the bromine ions do not leave the cluster during the calculation of 25 ps. The ability of the cluster containing molecular oxygen to absorb the infrared (IR) radiation is reduced in the frequency range of 0 ≤ ω ≤ 3500 cm -1 when the number of the bromine ions in the cluster grows. The intensity of the Raman spectrum is not changed significantly when the Br - ions are added to the ozone-containing system. The power of the emitted IR radiation is increased when the number of bromine ions grows in the oxygen-containing system. The data obtained in this study on the IR and the Raman spectra of the water clusters that contain ozone, oxygen, and Br - can be used to develop an investigation of the mechanisms of ozone depletion

Ключевые слова (''Своб.индексиров.''): 1/f-noise--first passage time--avalanches
Аннотация: A study has been made on the statistics of fluctuations in a spatially distributed system, which describes the interaction of nonequilibrium phase transitions. It is shown that at a certain intensity of external white noise acting on phase transitions, the time and spatial spectra of fluctuations have power laws S(f)∼f−α and S(k)∼k−γ. The dependence of the exponents α and γ on the value of the diffusion coefficient determining the spatial interaction of fluctuations have been found. Extreme low-frequency fluctuations has been revealed and distribution functions of their duration P(τ)∼τ−β and size P(s)∼s−ν have been determined. It has been found that the exponent α of the frequency dependence of time spectra and the exponent β of the distribution function of the fluctuation duration are related by the relation α+β=2. The exponent of the spatial spectrum γ and the exponent of the size distribution function ν are related by a similar relation: γ+ν=2. The results of experimental studies on fluctuations in a typical nonequilibrium phase transition such as transient modes of water boiling on a wire heater are presented. It was demonstrated that the critical exponents, which describe the power dependence of power spectra of fluctuations and the amplitude distribution of extreme surges, are related by the relation α+β=2 both in experiments and in the theoretical model of interacting heterogeneous phase transitions

Ключевые слова (''Своб.индексиров.''): fluctuations --1/f spectrum --gibbs-shannon informational entropy
Аннотация: Analysis of the control and subordination is carried out for the system of nonlinear stochastic equations describing fluctuations with the 1/f spectrum and with the interaction of nonequilibrium phase transitions. It is shown that the control equation of the system has a distribution function that decreases upon an increase in the argument in the same way as the Gaussian distribution function. Therefore, this function can be used for determining the Gibbs-Shannon informational entropy. The local maximum of this entropy is determined, which corresponds to tuning of the stochastic equations to criticality and indicates the stability of fluctuations with the 1/f spectrum. The values of parameter q appearing in the definition of these entropies are determined from the condition that the coordinates of the Gibbs-Shannon entropy maximum coincide with the coordinates of the Tsallis entropy maximum and the Renyi entropy maximum for distribution functions with a power dependence
