Three closely connected fields of research are integrated in the Project: 1) stochastic processes in the interaction of dense plasma and materials; 2) noise-induced anomalous transport phenomena; 3) noise-induced bifurcations and phase transitions in eco-systems. The primary aim is to elaborate, based on the universality of the theory of stochastic processes, a phenomenological model to describe the interaction of plasma pulses with materials, which would enable us to work out plasma focus installations and apply them for the production of new materials. The second aim is to analyze the dynamics of nano-particles in periodic structures, in which the particles are subjected to both equilibrium (thermal) and non-equilibrium fluctuations. Based on the anomalous transport phenomena observed in particle dynamics (such as noise-induced current reversals, negative mobility, anomalous diffusion etc.), applications in different fields are planned to propose, e.g. separation of nano-particles, control of the amplification of weak signals on the background of intense noise etc. The third aim is to establish whether there are cases in which variation of the parameters of environmental fluctuations can cause qualitative changes (catastrophic jumps included) encountered in natural eco-systems. The results expected would be important in preserving the stability of eco-systems in technogenic environments. |
