Calculating the symmetry number of flexible sphere clusters
Emilio Zappa, Miranda Holmes-Cerfon
We present a theoretical and computational framework to compute the symmetry number of a flexible sphere cluster in , using a definition of symmetry that arises natur…
A group theoretical approach to structural transitions of icosahedral quasicrystals and point arrays
Emilio Zappa, Eric C. Dykeman, James A. Geraets +1
In this paper we describe a group theoretical approach to the study of structural transitions of icosahedral quasicrystals and point arrays. We apply the concept of Schur rotations…
Orbits of crystallographic embedding of non-crystallographic groups and applications to virology
Reidun Twarock, Motiejus Valiunas, Emilio Zappa
The architecture of infinite structures with non-crystallographic symmetries can be modeled via aperiodic tilings, but a systematic construction method for finite structures with n…
A Ginzburg-Landau model for the expansion of a dodecahedral viral capsid
Emilio Zappa, Giuliana Indelicato, Alberto Albano +1
We propose a Ginzburg-Landau model for the expansion of a dodecahedral viral capsid during infection or maturation. The capsid is described as a dodecahedron whose faces, meant to…
