Controlling the shape and topology of two-component colloidal membranes
Ayantika Khanra, Leroy L. Jia, Noah P. Mitchell +5
Changes in the geometry and topology of self-assembled membranes underlie diverse processes across cellular biology and engineering. Similar to lipid bilayers, monolayer colloidal…
Axisymmetric membranes with edges under external force: buckling, minimal surfaces, and tethers
Leroy L. Jia, Steven Pei, Robert A. Pelcovits +1
We use theory and numerical computation to determine the shape of an axisymmetric fluid membrane with a resistance to bending and constant area. The membrane connects two rings in…
Deformation and orientational order of chiral membranes with free edges
Lijie Ding, Robert A. Pelcovits, Thomas R. Powers
Motivated by experiments on colloidal membranes composed of chiral rod-like viruses, we use Monte Carlo methods to determine the phase diagram for the liquid crystalline order of t…
Shapes of fluid membranes with chiral edges
Lijie Ding, Robert A. Pelcovits, Thomas R. Powers
We carry out Monte Carlo simulations of a colloidal fluid membrane composed of chiral rod-like viruses. The membrane is modeled by a triangular mesh of beads connected by bonds in…
Topological structure and dynamics of three dimensional active nematics
Guillaume Duclos, Raymond Adkins, Debarghya Banerjee +13
Point-like motile topological defects control the universal dynamics of diverse two-dimensional active nematics ranging from shaken granular rods to cellular monolayers. A comparab…
Force induced formation of twisted chiral ribbons
Andrew Balchunas, Leroy L. Jia, Mark Zakhary +3
We study the emergence of helical structures subjected to a stretching force, demonstrating that the force transforms disk-shaped colloidal membranes into twisted chiral ribbons of…
