Complexity in surfaces of densest packings for families of polyhedra
Elizabeth R. Chen, Daphne Klotsa, Michael Engel +2
Packings of hard polyhedra have been studied for centuries due to their mathematical aesthetic and more recently for their applications in fields such as nanoscience, granular and…
Understanding shape entropy through local dense packing
Greg van Anders, Daphne Klotsa, N. Khalid Ahmed +2
Entropy drives the phase behavior of colloids ranging from dense suspensions of hard spheres or rods to dilute suspensions of hard spheres and depletants. Entropic ordering of anis…
Emergent collective phenomena in a mixture of hard shapes through active rotation
Nguyen H. P. Nguyen, Daphne Klotsa, Michael Engel +1
We investigate collective phenomena with rotationally driven spinners of concave shape. Each spinner experiences a constant internal torque in either a clockwise or counterclockwis…
Entropically Patchy Particles: Engineering Valence through Shape Entropy
Greg van Anders, N. Khalid Ahmed, Ross Smith +2
Patchy particles are a popular paradigm for the design and synthesis of nanoparticles and colloids for self-assembly. In "traditional" patchy particles, anisotropic interactions ar…
