Dynamical Ordering and Directional Locking for Particles Moving<? format?> over Quasicrystalline Substrates

C Reichhardt, CJ Olson Reichhardt - Physical Review Letters, 2011 - APS
We use molecular dynamics simulations to study the driven phases of particles such as
vortices or colloids moving over a decagonal quasiperiodic substrate. In the regime where …

What phasons look like: particle trajectories in a quasicrystalline potential

JA Kromer, M Schmiedeberg, J Roth, H Stark - Physical review letters, 2012 - APS
Among the distinctive features of quasicrystals—structures with long-range order but without
periodicity—are phasons. Phasons are hydrodynamic modes that, like phonons, do not cost …

Rhombic preordering on a square substrate

T Neuhaus, M Marechal, M Schmiedeberg, H Löwen - Physical Review Letters, 2013 - APS
A competition of incommensurate symmetries occurs whenever a system is forced to
conform to an ordering that is different from the intrinsically preferred structure of the system …

Tuning the stability of a model quasicrystal and its approximants with a periodic substrate

NR Varela-Rosales, M Engel - Soft Matter, 2024 - pubs.rsc.org
Quasicrystals and their periodic approximants are complex crystalline phases. They have
now been observed in many metallic alloys, soft matter systems, and particle simulations. In …

Structural ordering of trapped colloids with competing interactions

LQ Costa Campos, SWS Apolinario, H Löwen - Physical Review E—Statistical …, 2013 - APS
The structure of colloids with competing interactions which are confined in a harmonic
external trap potential is analyzed numerically by energy minimization in two spatial …

Comparing light-induced colloidal quasicrystals with different rotational symmetries

M Schmiedeberg, H Stark - Journal of Physics: Condensed …, 2012 - iopscience.iop.org
Quasicrystals are aperiodic structures with long-range orientational order. Unlike crystals,
quasicrystals can, in principle, possess any non-crystallographic rotational symmetry …

Morphology of monolayer films on quasicrystalline surfaces from the phase field crystal model

We present a computational study of the morphology of adsorbed monolayers on
quasicrystalline surfaces with five-and seven-fold symmetry. The phase field crystal model is …

Stabilizing quasicrystals composed of patchy colloids by narrowing the patch width

A Gemeinhardt, M Martinsons… - Europhysics …, 2019 - iopscience.iop.org
We explore the behavior of two-dimensional patchy colloidal particles with 8 or 10
symmetrically arranged patches by employing Monte Carlo simulations. The particles …

[HTML][HTML] Phase ordering of zig-zag and bow-shaped hard needles in two dimensions

R Tavarone, P Charbonneau, H Stark - The Journal of Chemical …, 2015 - pubs.aip.org
We perform extensive Monte Carlo simulations of a two-dimensional bent hard-needle
model in both its chiral zig-zag and its achiral bow-shape configurations and present their …

Phase behavior of colloidal monolayers in quasiperiodic light fields

J Mikhael, G Gera, T Bohlein, C Bechinger - Soft Matter, 2011 - pubs.rsc.org
We experimentally investigate the phase behavior of a dense two-dimensional system of
interacting colloidal particles subjected to a decagonal quasiperiodic potential landscape …
