Phys. Rev. Lett. 99, 086106 (2007) [4 pages]Helix Self-Assembly from Anisotropic MoleculesReceived 21 March 2007; published 24 August 2007 We explore the potential energy landscape for clusters composed of disklike ellipsoidal particles interacting via an anisotropic potential based on the elliptic contact function. Over a wide range of parameter space we find global potential energy minima consisting of helices composed of one or more strands. Characterizing the potential energy surface in the region of helical global minima reveals a topology associated with “structure-seeking” systems. This result indicates that the helices will self-assemble over a wide range of temperature. © 2007 The American Physical Society URL:
