Competing Active and Passive Interactions Drive Amoeba-like Living Crystallites and Ordered Bands
Abraham Mauleon-Amieva, Majid Mosayebi, James E. Hallett +4
Swimmers and self-propelled particles are physical models for the collective behaviour and motility of a wide variety of living systems, such as bacteria colonies, bird flocks and…
Yielding of a Model Glassformer: an Interpretation with an Effective System of Icosahedra
Rhiannon Pinney, Tanniemola B. Liverpool, C. Patrick Royall
We consider the yielding under simple shear of a binary Lennard-Jones glassformer whose super-Arrhenius dynamics are correlated with the formation of icosahedral structures. We rec…
Active suspensions have non-monotonic flow curves and multiple mechanical equilibria
Aurore Loisy, Jens Eggers, Tanniemola B. Liverpool
We point out unconventional mechanical properties of confined active fluids, such as bacterial suspensions, under shear. Using a minimal model of an active liquid crystal with no f…
Multiple phoretic mechanisms in the self-propulsion of a Pt-insulator Janus swimmer
Yahaya Ibrahim, Ramin Golestanian, Tanniemola B. Liverpool
We present a detailed theoretical study which demonstrates that electrokinetic effects can also play a role in the motion of metallic-insulator spherical Janus particles. Essential…
