0 Fluid and solid phases of the Gaussian core model
We study the structural and thermodynamic properties of a model of point particles interacting by means of a Gaussian pair potential first introduced by Stillinger [Stillinger F H 1976 J. Chem. Phys. 65 3968]. By employing integral equation theories for the fluid state and comparing with Monte Carlo simulation results, we establish the limits of applicability of various common closures and exam...

متن کاملGaussian core model in two dimensions. II. Solid and fluid phase topological distribution functions
Local structure in the two-dimensional Gaussian core model at p* = 3/2 has been anayzed through the topology of nearest-neighbor polygons. Disorder is revealed by the presence of nonhexagonal polygons (disclinations). Near the melting point most disclination polygons have either five or seven sides and these are present in nearly equal concentrations. The concentrations increase by an order of ...
متن کاملMean-field fluid behavior of the gaussian core model
We show that the Gaussian core model of particles interacting via a penetrable repulsive Gaussian potential, first considered by Stillinger [J. Chem. Phys. 65, 3968 (1976)], behaves as a weakly correlated "mean-field fluid" over a surprisingly wide density and temperature range. In the bulk, the structure of the fluid phase is accurately described by the random phase approximation for the direc...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
