Macroscopic current generated by local division and apoptosis in a minimal model of tissue dynamics
Emma Mitchell, Elsen Tjhung
We consider a minimal computational model of tissue dynamics with two active ingredients: local particle division and apoptosis. We neglect other non-equilibrium effects such as se…
Capillary interfacial tension in active phase separation
Giordano Fausti, Elsen Tjhung, Michael Cates +1
In passive fluid-fluid phase separation, a single interfacial tension sets both the capillary fluctuations of the interface and the rate of Ostwald ripening. We show that these phe…
Self-propulsion of active droplets without liquid-crystalline order
Rajesh Singh, Elsen Tjhung, Michael E. Cates
The swimming of cells, far from any boundary, can arise in the absence of long-range liquid-crystalline order within the cytoplasm, but simple models of this effect are lacking. He…
Chiral active matter: microscopic `torque dipoles' have more than one hydrodynamic description
Tomer Markovich, Elsen Tjhung, Michael E. Cates
Many biological systems, such as bacterial suspensions and actomyosin networks, form polar liquid crystals. These systems are `active' or far-from-equilibrium, due to local forcing…
Shear-induced first-order transition in polar liquid crystals
Tomer Markovich, Elsen Tjhung, Michael E. Cates
The hydrodynamic theory of polar liquid crystals is widely used to describe biological active fluids as well as passive molecular materials. Depending on the `shear-alignment param…
Banana and pizza-slice-shaped mesogens give a new constrained ferromagnet universality class
Xiuqi Ma, Elsen Tjhung
It has been known that at high density, the local orientation of banana-shaped molecules shows a spontaneously bent state, giving rise to interesting liquid-crystalline phases such…
