Merons Mediate Re-Ordering of Curved Rods Under Shear Flow
Nicholas W. Hackney, Joel T. Clemmer, Thomas O'Connor +1
Bent-core liquid crystals are a canonical example of a soft matter system whose behavior is controlled by a local preference for order that cannot be universally achieved. This geo…
Shear and crystallization in deformable granular packings: why don't auxetics order?
Joel T. Clemmer, Nicholas W. Hackney, Gary S. Grest
Shear of three-dimensional, highly compressed granular packings is simulated using a bonded particle approach that explicitly resolves elastic deformation. Varying Poisson's ratio…
Shape Elasticity in Colloidal Bent-Core Liquid Crystals
Nicholas W. Hackney, Joel T. Clemmer, Gary S. Grest
Curved particles have been shown to stabilize a range of states with unique order in dense suspensions of colloidal bent core liquid crystals. The shape of the colloidal rods encou…
Geometrically Frustrated Assembly at Finite Temperature: Phase Transitions from Self-Limiting to Bulk States
Nicholas Hackney, Gregory Grason
Geometric frustration is recognized to generate complex morphologies in self-assembling particulate and molecular systems. In bulk states, frustrated drives structured arrays of to…
Dispersed, condensed and self-limiting states of geometrically frustrated assembly
Nicholas W. Hackney, Christopher Amey, Gregory M. Grason
In self-assembling systems, geometric frustration leads to complex states characterized by internal gradients of shape misfit. Frustrated assemblies have drawn recent interest due…
