Multiscale modeling of polycrystalline graphene: A comparison of structure and defect energies of realistic samples from phase field crystal models
Petri Hirvonen, Mikko M. Ervasti, Zheyong Fan +7
We extend the phase field crystal (PFC) framework to quantitative modeling of polycrystalline graphene. PFC modeling is a powerful multiscale method for finding the ground state co…
Phase Field Crystal Study of Symmetric Tilt Grain Boundaries of Iron
A. Jaatinen, C. V. Achim, K. R. Elder +1
We apply the phase field crystal model to study the structure and energy of symmetric tilt grain boundaries of bcc iron in 3D. The parameters for the model are obtained by using a…
Phase Diagram and Commensurate-Incommensurate Transitions in the Phase Field Crystal Model with an External Pinning Potential
C. V. Achim, M. Karttunen, K. R. Elder +3
We study the phase diagram and the commensurate-incommensurate transitions in a phase field model of a two-dimensional crystal lattice in the presence of an external pinning potent…
Comment on: `Pipe Network Model for Scaling of Dynamic Interfaces in Porous Media'
M. Dube, M. Rost, K. R. Elder +3
We argue that a proposed exponent identity [Phys. Rev. Lett 85, 1238 (2000)] for interface roughening in spontaneous imbibition is wrong. It rests on the assumption that the fluctu…
Defects, order, and hysteresis in driven charge-density waves
Mikko Karttunen, Mikko Haataja, K. R. Elder +1
We model driven two-dimensional charge-density waves in random media via a modified Swift-Hohenberg equation, which includes both amplitude and phase fluctuations of the condensate…
Liquid Conservation and Non-local Interface Dynamics in Imbibition
M. Dube, M. Rost, K. Elder +3
The propagation and roughening of a liquid-gas interface moving through a disordered medium under the influence of capillary forces is considered. The system is described by a phas…
Flame propagation in random media
N. Provatas, T. Ala-Nissila, Martin Grant +2
We introduce a phase-field model to describe the dynamics of a self-sustaining propagating combustion front within a medium of randomly distributed reactants. Numerical simulations…
