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…
Minimum energy paths for conformational changes of viral capsids
Paolo Cermelli, Giuliana Indelicato, Emilio Zappa
In this work we study how a viral capsid can change conformation using techniques of Large Deviations Theory for stochastic differential equations. The viral capsid is a model of a…
Monte Carlo on manifolds: sampling densities and integrating functions
Emilio Zappa, Miranda Holmes-Cerfon, Jonathan Goodman
We describe and analyze some Monte Carlo methods for manifolds in Euclidean space defined by equality and inequality constraints. First, we give an MCMC sampler for probability dis…
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…
On the subgroup structure of the hyperoctahedral group in six dimensions
Emilio Zappa, Eric C. Dykeman, Reidun Twarock
We investigate the subgroup structure of the hyperoctahedral group in six dimensions. In particular, we study the subgroups isomorphic to the icosahedral group. We classify the ort…
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…
