Dimensional Crossover and Thermophysical Properties of Nanoscale Condensed Matter

Section: Soft matter
Original Author's Text: English

Abstract: he problem going to be discussed is as follows: how results for 3D systems transfer to results for 2D systems and vice versa. Obviously, such a 3D ↔ 2D dimensional crossover should be smooth and without discontinuities. Here, this problem is studied for a single-component classical liquid in a reduced geometry, namely for slit-like and cylindrical pores with the lower crossover dimensionality Dcros= 2 and Dcros= 1, correspondingly, which are filled by water molecules. The influence of the 3D ↔ 2D dimensional crossover on the effective critical exponents αeff , νeff , γeff and on the thermophysical properties such as the heat capacity Cv and the isothermal compressibility βT is investigated.

Key words: dimensional crossover, confined systems, effective critical exponents, isochoric heat capasity, isothermal compressibility.
