The picture shows the pressure dependences of the primary relaxation time for tested glass forming systems described by the NEW MODEL proposed by Aleksandra Drozd-Rrzoska (relation is given in the  picture).  Note the manifestation of the dynamic crossover phenomenon (different colors matched for portraying curves) associated with changes in parameter values in this Equation.

The NEW MODEL scaling equations developed in this report cover dynamical domains and can also be applied for other dynamical properties such as viscosity η(P), diffusion or electric conductivity.

This WEBSITE was created to realize the following, main  GOALS:

Soft Matter systems have common features, such as the dominance of elements or local structures on the mesoscale, combined with their relatively weak interactions, which turns out to be sufficient to obtain a tendency to self-organize with even a small change in parameters. This additionally leads to extraordinary sensitivity to even minor endogenous and exogenous factors, e.g., nanoparticles and pressure. In the case of the latter, relatively low pressures P~1 GPa, or even much lower ones, can lead to phases/states with exotic features, often persisting after decompression.

Worth stressing, that for "classical hard matter" systems, a pressure similar to that at the Earth's core (~300 GPa) is typically required, and the resulting "exotic" properties most often disappear upon decompression.
