Density Distribution in Soft Matter Crystals and Quasicrystals
Priya Subramanian, Daniel J. Ratliff, Alastair M. Rucklidge +1
The density distribution in solids is often represented as a sum of Gaussian peaks (or similar functions) centred on lattice sites or via a Fourier sum. Here, we argue that represe…
Deriving phase field crystal theory from dynamical density functional theory: consequences of the approximations
Andrew J. Archer, Daniel J. Ratliff, Alastair M. Rucklidge +1
Phase field crystal (PFC) theory, extensively used for modelling the structure of solids, can be derived from dynamical density functional theory (DDFT) via a sequence of approxima…
Which wavenumbers determine the thermodynamic stability of soft matter quasicrystals?
D. J. Ratliff, A. J. Archer, P. Subramanian +1
For soft matter to form quasicrystals an important ingredient is to have two characteristic lengthscales in the interparticle interactions. To be more precise, for stable quasicrys…
Structural crossover in a model fluid exhibiting two length scales: repercussions for quasicrystal formation
M. C. Walters, P. Subramanian, A. J. Archer +1
We investigate the liquid state structure of the two-dimensional (2D) model introduced by Barkan et al. [Phys. Rev. Lett. 113, 098304 (2014)], which exhibits quasicrystalline and o…
