Cell division sets a universal flow geometry in cell layers
Tianxiang Ma, Lasse Bonn, Valeriia Grudtsyna +4
Collective flows in epithelial tissues contain a geometric backbone of vortical interfaces whose statistics exhibit hallmarks of critical percolation and conformal invariance. Yet…
Dispersion of activity at an active-passive nematic interface
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Efficient nutrient mixing is crucial for the survival of bacterial colonies and other living systems. This raises the question of whether the optimization of mixing through the eme…
Dynamics of two-dimensional liquid bridges
Rodrigo C. V. Coelho, Luis A. R. G. Cordeiro, Rodrigo B. Gazola +1
We have simulated the motion of a single vertical, two-dimensional liquid bridge spanning the gap between two flat, horizontal solid substrates of given wettabilities, using a mult…
Binary Mixtures of Locally Coupled Mobile Oscillators
Gonçalo Paulo, Mykola Tasinkevych
We study synchronization dynamics in binary mixtures of locally coupled Kuramoto oscillators which perform Brownian motion in a two-dimensional box. We introduce two models, where…
Wound opening in a thin incompressible viscoelastic tissue
G. M. Carvalho, N. A. M. Araújo, P. Patrício
We develop a model to investigate analytically and numerically the mechanics of wound opening made in a viscoelastic, isotropic, homogeneous, and incompressive thin tissue. This pr…
Enhanced diffusivity in microscopically reversible active matter
Artem Ryabov, Mykola Tasinkevych
Physics of self-propelled objects at the nanoscale is a rapidly developing research field where recent experiments focused on motion of individual catalytic enzymes. Contrary to th…
Director alignment at the nematic-isotropic interface: elastic anisotropy and active anchoring
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Activity in nematics drives interfacial flows that lead to preferential alignment that is tangential or planar for extensile systems (pushers) and perpendicular or homeotropic for…
The cell adaptation time sets a minimum length scale for patterned substrates
Diogo E. P. Pinto, Gonca Erdemci-Tandogan, M. Lisa Manning +1
The structure and dynamics of tissue cultures depend strongly on the physical and chemical properties of the underlying substrate. Inspired by previous advances in the context of i…
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…
Propagation of active nematic-isotropic interfaces on substrates
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Motivated by results for the propagation of active-passive interfaces of bacterial Serratia marcescens swarms [Nat. Comm., 9, 5373 (2018)] we use a hydrodynamic multiphase model to…
Lattice-Boltzmann simulation of free nematic-isotropic interfaces
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use a hybrid method of lattice Boltzmann and finite differences to simulate flat and curved interfaces between the nematic and isotropic phases of a liquid crystal described by…
Active nematic-isotropic interfaces in channels
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use numerical simulations to investigate the hydrodynamic behavior of the interface between nematic (N) and isotropic (I) phases of a confined active liquid crystal. At low acti…
Multiple timescale contact charging
T. Shinbrot, B. Ferdowsi, S. Sundaresan +1
Contact charging between insulators is one of the most basic, yet least well understood, of physical processes. For example we have no clear theory for how insulators recruit enoug…
Mechanical equilibrium of aggregates of dielectric spheres
A. F. V. Matias, T. Shinbrot, N. A. M. Araujo
Industrial as well as natural aggregation of fine particles is believed to be associated with electrostatics. Yet like charges repel, so it is unclear how similarly treated particl…
Dynamical demixing of a binary mixture under sedimentation
A. S. Nunes, R. C. V. Coelho, V. C. Braz +2
We investigate the sedimentation dynamics of a binary mixture, the species of which differ by their Stokes coefficients but are identical otherwise. We analyze the sedimentation dy…
Effective squirmer models for self-phoretic chemically active spherical colloids
M. N. Popescu, W. E. Uspal, Z. Eskandari +2
Various aspects of self-motility of chemically active colloids in Newtonian fluids can be captured by simple models for their chemical activity plus a phoretic slip hydrodynamic bo…
Field-driven dynamical demixing of binary mixtures
André S. Nunes, Akshat Gupta, Nuno A. M. Araújo +1
We consider mixtures of two species of spherical colloidal particles that differ in their hydrodynamic radii, but are otherwise identical, in the presence of an external field. Sin…
When is a surface foam-phobic or foam-philic?
Miguel A. C. Teixeira, Steve Arscott, Simon J. Cox +1
By integrating the Young-Laplace equation, including the effects of gravity, we have calculated the equilibrium shape of the two-dimensional Plateau borders along which a vertical…
Percolation in binary and ternary mixtures of patchy colloids
Felix Seiferling, Daniel de las Heras, Margarida M. Telo da Gama
We investigate percolation in binary and ternary mixtures of patchy colloidal particles theoretically and using Monte Carlo simulations. Each particle has three identical patches,…
Kinetic control of the coverage of oil droplets by DNA-functionalised colloids
Darshana Joshi, Dylan Bargteil, Alessio Caciagli +7
We report a study of reversible adsorption of DNA-coated colloids on complementary functionalized oil droplets. We show that it is possible to control the surface coverage of oil d…
Temperature (de)activated patchy colloidal particles
Daniel de las Heras, Margarida M. Telo da Gama
We present a new model of patchy particles in which the interaction sites can be activated or deactivated by varying the temperature of the system. We study the thermodynamics of t…
Relaxation dynamics of functionalized colloids on attractive substrates
C. S. Dias, C. Braga, N. A. M. Araujo +1
Particle-based simulations are performed to study the post-relaxation dynamics of functionalized (patchy) colloids adsorbed on an attractive substrate. Kinetically arrested structu…
Self-assembly of colloidal bands driven by a periodic external field
A. S. Nunes, N. A. M. Araujo, M. M. Telo da Gama
We study the formation of bands of colloidal particles driven by periodic external fields. Using Brownian dynamics, we determine the dependence of the band width on the strength of…
