Grain extraction and microstructural analysis method for two-dimensional poly and quasicrystalline solids
Petri Hirvonen, Gabriel Martine La Boissonière, Zheyong Fan +4
While the microscopic structure of defected solid crystalline materials has significant impact on their physical properties, efficient and accurate determination of a given polycry…
Long wavelength properties of phase field crystal models with second order dynamics
V. Heinonen, C. V. Achim, T. Ala-Nissila
The phase field crystal (PFC) approach extends the notion of phase field models by describing the topology of the microscopic structure of a crystalline material. One of the conseq…
Consistent Hydrodynamics for Phase Field Crystals
V. Heinonen, C. V. Achim, J. M. Kosterlitz +3
We use the amplitude expansion in the phase field crystal framework to formulate an approach where the fields describing the microscopic structure of the material are coupled to a…
Growth modes of quasicrystals
C. V. Achim, M. Schmiedeberg, H. Löwen
The growth of quasicrystals, i.e., aperiodic structures with long-range order, seeded from the melt is investigated using a dynamical phase field crystal model. Depending on the th…
Phase-field-crystal models and mechanical equilibrium
V. Heinonen, C. V. Achim, K. R. Elder +2
Phase field crystal (PFC) models constitute a field theoretical approach to solidification, melting and related phenomena at atomic length and diffusive time scales. One of the adv…
Vacancy diffusion in colloidal crystals as determined by dynamical density-functional theory and the phase-field-crystal model
Sven van Teeffelen, Cristian Vasile Achim, Hartmut Löwen
A two-dimensional crystal of repulsive dipolar particles is studied in the vicinity of its melting transition by using Brownian dynamics computer simulation, dynamical density func…
