Structural Transition in the Ising-Model Interface

We have studied the interface between regions of opposite spin in the simple cubic Ising model. Low-temperature expansions of moments of the gradient of the density profile and of the slope at its

INTERFACE TENSION IN THREE-DIMENSIONAL SYSTEMS FROM FIELD THEORY

Structure and Free Energy of the Interface between Fluid Phases in Equilibrium near the Critical Point

The theory of van der Waals and of Cahn and Hilliard, which yields the density or concentration profile through an interface and the associated interfacial tension, is generalized by replacing the

Structure and thermodynamics of the liquid–vapor interface

This paper is concerned with the effects that density fluctuations in different regions of a liquid–vapor interface have on the interfacial thermodynamic and structural properties. The total volume V

Interfacial Roughening in Field Theory

In the rough phase, the width of interfaces separating different phases of statistical systems increases logarithmically with the system size. This phenomenon is commonly described in terms of the

Crystal statistics. I. A two-dimensional model with an order-disorder transition

The partition function of a two-dimensional "ferromagnetic" with scalar "spins" (Ising model) is computed rigorously for the case of vanishing field. The eigenwert problem involved in the

Finite-size effects in fluid interfaces

``Intrinsic'' profiles and capillary waves at homopolymer interfaces: A Monte Carlo study

A popular concept which describes the structure of polymer interfaces by ``intrinsic profiles'' centered around a two dimensional surface, the ``local interface position'', is tested by extensive

Phase Separation in the Two-Dimensional Ising Ferromagnet

The interface density profile of the two-dimensional Ising ferromagnet is investigated for all temperatures below the critical point. The width of the interface diverges in the thermodynamic limit.
