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…
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…
Ordering of Binary Colloidal Crystals by Random Potentials
Andre S. Nunes, Sabareesh K. P. Velu, Iryna Kasianiuk +6
Structural defects are ubiquitous in condensed matter, and not always a nuisance. For example, they underlie phenomena such as Anderson localization and hyperuniformity, and they a…
Enhanced propagation of motile bacteria on surfaces due to forward scattering
Stanislaw Makarchuk, Vasco C. Braz, Nuno A. M. Araújo +2
How motile bacteria move near a surface is a problem of fundamental biophysical interest and is key to the emergence of several phenomena of biological, ecological and medical rele…
