Two-dimensional fluid with competing interactions exhibiting microphase separation: theory for bulk and interfacial properties.
Colloidal particles that are confined to an interface such as the air-water interface are an example of a two-dimensional fluid. Such dispersions have been observed to spontaneously form cluster and stripe morphologies in certain systems with isotropic pair potentials between the particles, due to the fact that the pair interaction between the colloids has competing attraction and repulsion ove...

متن کاملModel colloidal fluid with competing interactions: bulk and interfacial properties.
Using a simple mean field density functional theory (DFT), the authors investigate the structure and phase behavior of a model colloidal fluid composed of particles interacting via a pair potential which has a hard core of diameter sigma, is attractive Yukawa at intermediate separations, and is repulsive Yukawa at large separations. The authors analyze the form of the asymptotic decay of the bu...
متن کاملTwo-dimensional systems with competing interactions: microphase formation versus liquid-vapour phase separation.
Based on extensive integral-equation calculations and on complementary Monte Carlo simulations we have investigated the phase behaviour of a class of two-dimensional model systems where particles interact via short-range attractive and long-range repulsive potentials. While for a particular member of this class of systems microphase formation has already been studied in detail in the literature...
متن کاملTwo-dimensional systems with competing interactions: microphase formation under the effect of a disordered porous matrix
We have investigated the effect of a disordered porous matrix on the cluster microphase formation of a two dimensional system where fluid particles interact via competing interactions. To this end we have performed extensive Monte Carlo simulations and have systematically varied the densities of the fluid and of the matrix as well as the interaction between the matrix particles and between the ...
