We studied critical adsorption in Ising systems (d=3) using functional theory and simulations. The energy density
Area of Science:
- Statistical Mechanics
- Condensed Matter Physics
Background:
- Critical adsorption phenomena in semi-infinite systems.
- Ising universality class and normal surface universality class interactions.
Purpose of the Study:
- Investigate critical adsorption in 3D Ising systems with normal surface class walls.
- Quantify energy density and order parameter properties near critical points.
Main Methods:
- Local-functional theory
- Monte Carlo simulations
Main Results:
- Surface wetting observed under collinear/anticollinear field conditions.
- Non-monotonic behavior of energy density found due to interface effects.
Conclusions:
- The study reveals complex critical adsorption behavior in specific Ising systems.
- Non-monotonic scaling densities challenge conventional understanding under wetting conditions.

The point in the energy diagram at which the system’s potential energy is the lowest is known as the local minima. The system tends to stay in this position indefinitely unless acted upon by a net force. The slope of the potential energy diagram at the local minima is zero, indicating that zero net force is acting on the system. The...
