Instabilities in a growing system of active particles: scalar and vector systems
Forouh Maleki, Ali Najafi
The physics of micron-scale biological colonies usually benefits from different out-of-equilibrium sources. In bacterial colonies and cellular tissues, the growth process is among…
Self-generated gradients stabilize the hydrodynamic instabilities in active suspensions
Mehrana R. Nejad, Ali Najafi
Ordered phases emerged in active suspensions of polar swimmers are under long-wavelength hydrodynamic mediated instabilities. In this letter, we show that chemical molecules dissol…
Long-wavelength instabilities in a system of interacting active particles
Zahra Fazli, Ali Najafi
Based on a microscopic model, we develop a continuum description for a suspension of microscopic self propelled particles. With this continuum description we study the role of long…
Symplectic and antiplectic waves in an array of beating cilia attached to a closed body
Aref Ghorbani, Ali Najafi
By taking into account the hydrodynamic interactions in a one dimensional array of model cilia attached to a no-slip cylinderical surface, we investigate their synchronized motion.…
A 2-D suspension of active agents: the role of fluid mediated interactions
Hojjat Behmadi, Zahra Fazli, Ali Najafi
Taking into account simultaneously the Vicsek short range ordering and also the far-field hydrodynamic interactions mediated by the ambient fluid, we investigate the role of long r…
Systematic investigation of projectile fragmentation using beams of unstable B and C isotopes
R. Thies, A. Heinz, T. Adachi +119
Background: Models describing nuclear fragmentation and fragmentation-fission deliver important input for planning nuclear physics experiments and future radioactive ion beam facil…
