We present a Landau theory for large-l orientational phase transitions and apply it to the assembly of icosahedral viral capsids. The theory predicts two distinct types of ordering transitions. Transitions dominated by the l=6,10,12, and 18 icosahedral spherical harmonics resemble robust first-order phase transitions that are not significantly affected by chirality. The remaining transitions depend essentially on including mixed l states denoted as l=15+16 corresponding to a mixture of l=15 and… 

Invariant theory and orientational phase transitions.

This paper addresses fundamental problems that arise with the Landau theory when it is applied to rotational symmetry breaking transitions of more complex particle clusters that involve order parameters characterized by larger values of the l index of the dominant spherical harmonic that describes the broken symmetry state.

Self-assembly of proteins into a virus capsid by the methods of molecular dynamics is considered, where a single capsid is dissociated by an application of a high temperature for a variable period and then the system is cooled down to allow for self-assembly.

Freezing on a sphere

It is shown that freezing on the surface of a sphere proceeds by the formation of a single, encompassing crystalline ‘continent’, which forces defects into 12 isolated ‘seas’ with the same icosahedral symmetry as footballs and viruses.

Ground state instabilities of protein shells are eliminated by buckling.

It is argued that the well-width appropriate for protein shells lies below the structural instability threshold, which means that the self-assembly of protein shells with a well-defined, stable structure is possible only if the bending energy of the shell is sufficiently low so that the FvK number of the assembled shell is above the buckling threshold.

Aspects of Nucleation: Fluctuations, Nonuniform Order, and Curved Surfaces

Transitions between various states of matter occur everywhere and are integral in the processes that make life, as we know it, possible. Given such importance in everyday life, it makes sense that

Aspects of nucleation on curved and flat surfaces.

This work investigates the energetics of droplets sourced by the thermal fluctuations in a system undergoing a first-order transition to two dimensions with explicit calculations in the plane and on the sphere using an isoperimetric inequality and a theorem on the inequality's saturation.

Surface Patterns On Single Cells: A Consequence Of A Phase Transition To Modulated Phases

Patterns are ubiquitous in the world around us, and we have only begun to scratch the surface of understanding their complexity and formation. In this thesis, we draw inspiration from rigid,

Phase transitions in virology

It is suggested that the advantages of abstract, simplified pictures used in physics are also the key to properly understanding the origins and evolution of complexity in viruses and how minimal models provide deep insights into a diverse array of problems.



Landau theory and the emergence of chirality in viral capsids

A generalized Landau-Brazovskii theory for the solidification of chiral molecules on a spherical surface is presented and the predictions of the theory are compared with recent numerical simulations.

Landau theory of crystallization and the capsid structures of small icosahedral viruses

A new approach to the capsid structures of small viruses with spherical topology and icosahedral symmetry is proposed. It generalizes Landau theory of crystallization to describe icosahedral viral

Elasticity theory and shape transitions of viral shells.

It is found that the transition from icosahedral to spherocylindrical symmetry is continuous or weakly first order near the onset of buckling, leading to extensive shape degeneracy.

Virus shapes and buckling transitions in spherical shells.

We show that the icosahedral packings of protein capsomeres proposed by Caspar and Klug for spherical viruses become unstable to faceting for sufficiently large virus size, in analogy with the

Density-wave theory of the capsid structure of small icosahedral viruses.

An explicit method which predicts the positions of centers of mass for the proteins constituting the viral capsid shell is developed which describes in a uniform way both the structures satisfying the well-known Caspar and Klug geometrical model for capsid construction and those violating it.

Assembly of viruses and the pseudo-law of mass action.

A model for capsid assembly, the "assembly line model," is examined that can be analyzed analytically and shows that, in this model, efficient viral assembly from a supersaturated solution is characterized by a shock front propagating in the assembly configuration space from small to large aggregate sizes.

Virus Maturation Involving Large Subunit Rotations and Local Refolding

The structure of bacteriophage HK97 capsid, Head-II, was recently solved by crystallography, revealing a catenated cross-linked topology and the inner surface of Prohead-II is negatively charged, suggesting that the transition is triggered electrostatically by DNA packaging.

Classical nucleation theory of virus capsids.

expression for the size of the critical capsid, the lag time, and the steady-state nucleation rate of capsids, and how they depend on both protein concentration and binding energy are found, explaining why capsid nucleation is a sensitive function of the ambient conditions.

Equilibrium self-assembly of small RNA viruses.

It is demonstrated that the conventional theory of self- assembly, which does describe the assembly of empty capsids, is in general not applicable to the self-assembly of RNA-encapsidating virions.

Encapsulation of a polymer by an icosahedral virus

This work performs Brownian dynamics on a coarse-grained model that describes the dynamics of icosahedral capsid assembly around a flexible polymer and identifies several mechanisms by which the polymer plays an active role in its encapsulation, including cooperative polymer–protein motions.
