20 Dec 2016 | Abstract: | Outermost occupied electron shells of chemical elements can have symmetries
resembling that of monopoles, dipoles, quadrupoles and octupoles corresponding
to filled s-, p-, d- and forbitals. Theoretically, elements with hexadecapolar
outer shells could also exist, but none of the known elements have filled
g-orbitals. On the other hand, the research paradigm of "colloidal atoms"
displays complexity of particle behaviour exceeding that of atomic
counterparts, which is driven by DNA functionalization, geometric shape and
topology and weak external stimuli. Here we describe elastic hexadecapoles
formed by polymer microspheres dispersed in a liquid crystal, a nematic fluid
of orientationally ordered molecular rods. Because of conically degenerate
boundary conditions, the solid microspheres locally perturb the alignment of
the nematic host, inducing hexadecapolar distortions that drive anisotropic
colloidal interactions. We uncover physical underpinnings of formation of
colloidal elastic hexadecapoles and describe the ensuing bonding inaccessible
to elastic dipoles, quadrupoles and other nematic colloids studied previously. | Source: | arXiv, 1612.6502 | Services: | Forum | Review | PDF | Favorites |
