Wetting and nonwetting near a tricritical point
Joseph O. Indekeu, Kenichiro Koga
The dihedral contact angles between interfaces in three-fluid-phase equilibria must be continuous functions of the bulk thermodynamic fields. This general argument, which we propos…
Coastlines and percolation in a model for hierarchical random deposition
Jonas Berx, Evi Bervoets, Claudiu V. Giuraniuc +1
We revisit a known model in which (conducting) blocks are hierarchically and randomly deposited on a -dimensional substrate according to a hyperbolic size law with the block siz…
Three-phase equilibria in density-functional theory: interfacial tensions
Kenichiro Koga, Joseph O. Indekeu
A mean-field density-functional model for three-phase equilibria in fluids (or other soft condensed matter) with two spatially varying densities is analyzed analytically and numeri…
Interfacial tension and wall energy of a Bose-Einstein condensate binary mixture: triple-parabola approximation
Zehui Deng, Bert Van Schaeybroeck, Chang-You Lin +2
Accurate and useful analytic approximations are developed for order parameter profiles and interfacial tensions of phase-separated binary mixtures of Bose-Einstein condensates. The…
Static interfacial properties of Bose-Einstein condensate mixtures
Joseph O. Indekeu, Chang-You Lin, Nguyen Van Thu +2
Interfacial profiles and interfacial tensions of phase-separated binary mixtures of Bose-Einstein condensates are studied theoretically. The two condensates are characterized by th…
Critical wetting, first-order wetting and prewetting phase transitions in binary mixtures of Bose-Einstein condensates
Bert Van Schaeybroeck, Joseph Indekeu
An ultralow-temperature binary mixture of Bose-Einstein condensates adsorbed at an optical wall can undergo a wetting phase transition in which one of the species excludes the othe…
Degree-dependent network growth: From preferential attachment to explosive percolation
Hans Hooyberghs, Bert Van Schaeybroeck, Joseph O. Indekeu
We present a simple model of network growth and solve it by writing down the dynamic equations for its macroscopic characteristics like the degree distribution and degree correlati…
Nonequilibrium wetting transition in a nonthermal 2D Ising model
Jef Hooyberghs, Joseph O. Indekeu
Nonequilibrium wetting transitions are observed in Monte Carlo simulations of a kinetic spin system in the absence of a detailed balance condition with respect to an energy functio…
Percolation on bipartite scale-free networks
Hans Hooyberghs, Bert Van Schaeybroeck, Joseph O. Indekeu
Recent studies introduced biased (degree-dependent) edge percolation as a model for failures in real-life systems. In this work, such process is applied to networks consisting of t…
Biased Percolation on Scale-free Networks
Hans Hooyberghs, Bert Van Schaeybroeck, André A. Moreira +3
Biased (degree-dependent) percolation was recently shown to provide new strategies for turning robust networks fragile and vice versa. Here we present more detailed results for bia…
Criticality on networks with topology-dependent interactions
C. V. Giuraniuc, J. P. L. Hatchett, J. O. Indekeu +4
Weighted scale-free networks with topology-dependent interactions are studied. It is shown that the possible universality classes of critical behaviour, which are known to depend o…
Transition temperatures and contact angles in the sequential-wetting scenario of n-alkanes on (salt) water
Volker C. Weiss, Joseph O. Indekeu
Alkanes of medium chain length show an unusual wetting behavior on (salt) water, exhibiting a sequence of two changes in the wetting state. When deposited on the water surface at l…
Effect of ion hydration on the first-order transition in the sequential wetting of hexane on brine
Volker C. Weiss, Joseph O. Indekeu
In recent experiments, a sequence of changes in the wetting state (`wetting transitions') has been observed upon increasing the temperature in systems consisting of pentane on pure…
