Two-dimensional active polar semiflexible polymer under shear flow
A. Lamura, R. G. Winkler
The nonequilibrium structural and dynamical properties of semiflexible active polar polymers subject to linear flow are studied by numerical simulations. Filaments are confined in…
Dynamical behavior of compound vesicles in wall-bounded shear flow
A. Lamura
We report a numerical study addressing the dynamics of compound vesicles confined in a channel under shear flow. The system comprises a smaller vesicle embedded within a larger one…
Phase segregation of liquid-vapor systems with a gravitational field
A. Lamura
Phase separation in the presence of external forces has attracted considerable attention since the initial works for solid mixtures. Despite this, only very few studies are availab…
Tethered flexible polymer under oscillatory linear flow

The non-equilibrium structural and dynamical properties of a flexible polymer tethered to a reflecting wall and subject to oscillatory linear flow are studied by numerical simulati…
Motility driven glassy dynamics in confluent epithelial monolayers
Souvik Sadhukhan, Manoj Kumar Nandi, Satyam Pandey +4
As wounds heal, embryos develop, cancer spreads, or asthma progresses, the cellular monolayer undergoes glass transition between solid-like jammed and fluid-like flowing states. Du…
Growth regimes in three-dimensional phase separation of liquid-vapor systems
Giuseppe Negro, Giuseppe Gonnella, Antonio Lamura +2
The liquid-vapor phase separation is investigated via lattice Boltzmann simulations in three dimensions. After expressing length and time scales in reduced physical units, we combi…

The dynamics and rheology of a vesicle confined in a channel under shear flow are studied at finite temperature. The effect of finite temperature on vesicle motion and system visco…
Shapes and dynamic regimes of a polar active fluid droplet under confinement
Adriano Tiribocchi, Mihir Durve, Marco Lauricella +3
Active droplets are artificial microswimmers built from a liquid dispersion by microfluidic tools and showing self-propelled motion. These systems hold particular interest for mimi…
Lattice Boltzmann modeling of cholesteric liquid crystal droplets under an oscillatory electric field
