Percolation in binary mixtures of linkers and particles: chaining {\it {vs}} branching
M. Gouveia, C. S. Dias, J. M. Tavares
Equilibrium gels of colloidal particles can be realized through the introduction of a second species, a linker that mediates the bonds between the colloids. A gel forming binary mi…
Building up DNA, bit by bit: a simple description of chain assembly
R. Foffi, F. Sciortino, J. M. Tavares +1
We simulate the assembly of DNA copolymers from two types of short duplexes (short double strands with a single-stranded overhang at each end), as described by the oxDNA model. We…
Smoluchowski equations for linker-mediated irreversible aggregation
J. M. Tavares, G. C. Antunes, C. S. Dias +2
In order to study linker-mediated aggregation of colloidal particles with limited valence, we combine kinetic Monte Carlo simulations and an approximate theory based on the Smoluch…
Dynamics of patchy particles in and out of equilibrium
J. M. Tavares, C. S. Dias, N. A. M. Araújo +1
We combine particle-based simulations, mean-field rate equations, and Wertheim's theory to study the dynamics of patchy particles in and out of equilibrium, at different temperatur…
Reentrant spinodals and the Speedy scenario in colloidal model systems
Lorenzo Rovigatti, Valentino Bianco, José Maria Tavares +1
A re-entrant gas-liquid spinodal was proposed as a possible explanation of the apparent divergence of the compressibility and specific heat on supercooling water. Such a counter in…
Dynamics of a network fluid within the liquid-gas coexistence region
C. S. Dias, J. M. Tavares, N. A. M. Araujo +1
Low-density networks of molecules or colloids are formed at low temperatures when the interparticle interactions are valence limited. Prototypical examples are networks of patchy p…
Three-dimensional patchy lattice model: ring formation and phase separation
J. M. Tavares, N. G. Almarza, M. M. Telo da Gama
We investigate the structural and thermodynamic properties of a model of particles with patches of type and patches of type . Particles are placed on the sites of a…
Self-assembly in chains, rings and branches: a single component system with two critical points
Lorenzo Rovigatti, José Maria Tavares, Francesco Sciortino
We study the interplay between phase separation and self-assembly in chains, rings and branched structures in a model of particles with dissimilar patches. We extend Wertheim's fir…
Computing the phase diagram of binary mixtures: a patchy particle case study
Lorenzo Rovigatti, Daniel de las Heras, José Maria Tavares +2
We investigate the phase behaviour of 2D mixtures of bi-functional and three-functional patchy particles and 3D mixtures of bi-functional and tetra-functional patchy particles by m…
Three-dimensional patchy lattice model for empty fluids
N. G. Almarza, J. M. Tavares, E. G. Noya +1
The phase diagram of a simple model with two patches of type A and ten patches of type B (2A10B) on the face centred cubic lattice has been calculated by simulations and theory. As…
Properties of patchy colloidal particles close to a surface: a Monte Carlo and density functional study
Nicoletta Gnan, Daniel de las Heras, José Maria Tavares +2
We investigate the behavior of a patchy particle model close to a hard-wall via Monte Carlo simulation and density functional theory (DFT). Two DFT approaches, based on the homogen…
The condensation and ordering of models of empty liquids
N. G. Almarza, J. M. Tavares, M. Simões +1
We consider a simple model consisting of particles with four bonding sites ("patches"), two of type A and two of type B, on the square lattice, and investigate its global phase beh…
Bicontinuous and mixed gels in binary mixtures of patchy colloidal particles
Daniel de las Heras, José Maria Tavares, Margarida M. Telo da Gama
We investigate the thermodynamics and percolation regimes of model binary mixtures of patchy colloidal particles. The particles of each species have three sites of two types, one o…

N. G. Almarza, J. M. Tavares, M. M. Telo da Gama
The criticality of self-assembled rigid rods on triangular lattices is investigated using Monte Carlo simulation. We find a continuous transition between an ordered phase, where th…
Phase diagrams of binary mixtures of patchy colloids with distinct numbers and types of patches: The empty fluid regime
Daniel de las Heras, José Maria Tavares, Margarida M. Telo da Gama
We investigate the effect of distinct bonding energies on the onset of criticality of low functionality fluid mixtures. We focus on mixtures of particles with two and three patches…

Daniel de las Heras, José M. Tavares, Margarida M. Telo da Gama
We calculate the network fluid regime and phase diagrams of binary mixtures of patchy colloids, using Wertheim's first order perturbation theory and a generalization of Flory-Stock…
The nature of the phase transition in dipolar fluids
J. M. Tavares, J. J. Weis, M. M. Telo da Gama
Monte Carlo computer simulations of a quasi two dimensional (2D) dipolar fluid at low and intermediate densities indicate that the structure of the fluid is well described by an id…
