Primary scaling densities in the critical adsorption of Ising systems

Zoran Borjan

University of Belgrade, Serbia

C

ritical adsorption of Ising systems in the presence of normal surface universality class is considered along the critical

isochore, near coexistence and along the critical isotherm in cases of energy density and order-parameter and energy

density, respectively. The problem is treated theoretically and by Monte-Carlo simulation method in spatial dimensions d=2,

d=3 and theoretically in the mean-field limit. Excellent agreement between theory and the Monte-Carlo method is achieved

within the study in d=3. Primary scaling densities such as order parameter and energy density manifest monotone behaviors

with the relevant exception of non-monotone behaviors of energy density whenever an interface is present in systems. Two-

dimensional analysis along the critical isotherm points to a new characteristic of low-dimensional Ising systems consisting

of the interface de-localization. Above results are relevant to binary liquid mixtures, liquid-gas systems, ferromagnets, binary

alloys and other physical systems of the Ising universality class near their corresponding critical points.

hh1>0 and hh1<0, respectively, where h1=+∞ is the surface magnetic field, and h is the weak bulk magnetic field.
