Covariant description of the colloidal dynamics on curved manifolds
Pavel Castro-Villarreal, César O. Solano-Cabrera, Ramón Castañeda-Priego
Brownian motion is a universal characteristic of colloidal particles embedded in a host medium, and it is the fingerprint of molecular transport or diffusion, a generic feature of…
Phase separation and dynamical arrest of protein solutions dominated by short-range attractions
Jan Hansen, Carolyn J. Moll, Leticia Lopez Flores +4
The interplay of phase separation and dynamical arrest can lead to the formation of gels and glasses, which is relevant for such diverse fields as hard and soft condensed matter ph…
Single file dynamics in soft materials
Alessandro Taloni, Ophir Flomenbom, Ramon Castaneda-Priego +1
The term single file (SF) dynamics refers to the motion of an assembly of particles through a channel with cross-section comparable to the particles' diameter. Single file diffusio…
Single-file dynamics of colloids in circular channels: time scales, scaling laws and their universality
Alejandro Villada-Balbuena, Antonio Ortiz-Ambriz, Pavel Castro-Villarreal +3
In colloidal systems, Brownian motion emerges from the massive separation of time and length scales associated to characteristic dynamics of the solute and solvent constituents. Th…
Determining depletion interactions by contracting forces
Nestor M. de los Santos-Lopez, Gabriel Perez-Angel, Ramon Castaneda-Priego +1
We introduce a general physical formulation that allows one to obtain uniquely the effectiveinteractions by contracting the bare forces, even in highly concentrated systems. We tes…
Arrested dynamics of the dipolar hard-sphere model
Luis Fernando Elizondo-Aguilera, Ernesto Carlos Cortés-Morales, Pablo F. Zubieta Rico +4
We report the combined results of molecular dynamics simulations and theoretical calculations concerning various dynamical arrest transitions in a model system representing a dipol…
Glassy dynamics in asymmetric binary mixtures of hard-spheres
Edilio Lázaro-Lázaro, Jorge Adrián Perera-Burgos, Patrick Laermann +8
The binary hard-sphere mixture is one of the simplest representations of a many-body system with competing time and length scales. This model is relevant to fundamentally understan…
Self-consistent generalized Langevin equation theory of the dynamics of multicomponent atomic liquids
Edilio Lázaro-Lázaro, Patricia Mendoza-Méndez, Luis Fernando Elizondo-Aguilera +5
A fundamental challenge of the theory of liquids is to understand the similarities and differences in the macroscopic dynamics of both colloidal and atomic liquids, which originate…
Short-time dynamics of monomers and dimers in quasi-two-dimensional colloidal mixtures
Erick Sarmiento-Gómez, José Ramón Villanueva-Valencia, Salvador Herrera-Velarde +4
We report on the short-time dynamics in colloidal mixtures made up of monomers and dimers highly confined between two glass-plates. At low concentrations, the experimental measurem…
Extended law of corresponding states for protein solutions
Florian Platten, Néstor E. Valadez-Pérez, Ramón Castañeda-Priego +1
The so-called extended law of corresponding states, as proposed by Noro and Frenkel [J. Chem. Phys. 113, 2941 (2000)], involves a mapping of the phase behaviors of systems with sho…
Colloids in light fields: particle dynamics in random and periodic energy landscapes
F. Evers, R. D. L. Hanes, C. Zunke +8
The dynamics of colloidal particles in potential energy landscapes have mainly been investigated theoretically. In contrast, here we discuss the experimental realization of potenti…
Towards a general definition of gelation for adhesive hard-sphere dispersions
Néstor E. Valadez-Pérez, Yun Liu, Aaron P. R. Eberle +2
One major goal in condensed matter physics is identifying the physical mechanisms that lead to arrested states of matter, especially gels and glasses. The complex nature and micros…
Density-dependent interactions and structure of charged colloidal dispersions in the weak screening regime
Luis F. Rojas-Ochoa, Ramon Castaneda-Priego, Vladimir Lobaskin +3
We determine the structure of charge-stabilized colloidal suspensions at low ionic strength over an extended range of particle volume fractions using a combination of light and sma…
On the macroion virial contribution to the osmotic pressure in charge-stabilized colloidal suspensions
E. Trizac, L. Belloni, J. Dobnikar +2
Our interest goes to the different virial contributions to the equation of state of charged colloidal suspensions. Neglect of surface effects in the computation of the colloidal vi…
Testing the relevance of effective interaction potentials between highly charged colloids in suspension
J. Dobnikar, R. Castañeda-Priego, H. H. von Grünberg +1
Combining cell and Jellium model mean-field approaches, Monte Carlo together with integral equation techniques, and finally more demanding many-colloid mean-field computations, we…
Macroion correlation effects in electrostatic screening and thermodynamics of highly charged colloids
Ramon Castaneda-Priego, Luis F. Rojas-Ochoa, Vladimir Lobaskin +1
We study macroion correlation effects on the thermodynamics of highly charged colloidal suspensions using a mean-field theory and primitive model computer simulations. We suggest a…
