Phase-field-crystal model for fcc ordering [PDF]
Physical Review E, 2010 We develop and analyze a two-mode phase-field-crystal model to describe fcc ordering. The model is formulated by coupling two different sets of crystal density waves corresponding to <111> and <200> reciprocal lattice vectors, which are chosen to form triads so as to produce a simple free- energy landscape with coexistence of crystal and ...

A parallelized model for coupled phase field and crystal plasticity simulation [PDF]
Computer Methods in Materials Science, 2016 The predictive simulation of materials with strong interaction between microstructural evolution and mechanical deformation requires the coupling of two or more multi-physics models.

Evaluation of Nanoscale Deformation Fields from Phase Field Crystal Simulations
Metals, 2022 Different methods for evaluation of displacement and strain fields based on phase field crystal (PFC) simulations are shown. Methods originally devised for molecular dynamics (MD) simulations or analysis of high-resolution microscopy images are adapted ...

A phase-field-crystal approach to critical nuclei [PDF]
Journal of Physics: Condensed Matter, 2010 We investigate a phase-field-crystal model for homogeneous nucleation. Instead of solving the time evolution of a density field towards equilibrium we use a String Method to identify saddle points in phase space. The saddle points allow to obtain the nucleation barrier and the critical nucleus.

Microscopic patterns in the 2D phase-field-crystal model
Nonlinearity, 2022 Abstract Using the recently developed theory of rigorously validated numerics, we address the phase-field-crystal model at the microscopic (atomistic) level. We show the existence of critical points and local minimizers associated with ‘classical’ candidates, grain boundaries, and localized patterns.

Development of phase-field model based on balance laws and thermodynamic discussion
AIP Advances, 2020 In this work, a phase-field model for recrystallization is developed based on the conservation laws. There has been no attempt to develop a phase-field model of recrystallization based on the conservation laws, even though various phase-field simulation ...

Scientific Reports, 2023 The highly-nonlinear chalcopyrite crystal family has experienced remarkable success as source crystals in the mid-infrared spectral range, such that these crystals are primary candidates for producing high terahertz frequency (i.e., $$\gtrsim$$ ≳ 10 THz)

Unwinding of a cholesteric liquid crystal and bidirectional surface anchoring [PDF]
, 2013 We examine the influence of bidirectional anchoring on the unwinding of a planar cholesteric liquid crystal induced by the application of a magnetic field. We consider a liquid crystal layer confined between two plates with the helical axis perpendicular

Investigation of the Direction of Spontaneous Magnetisation at 0 K in HoCo2 and TmFe2
Sultan Qaboos University Journal for Science, 2015 The direction of spontaneous magnetisation at 0 K across a phase orientation boundary in rare-earth laves phase compounds is computed as a function of the ratio of magnetic to electrostatic interactions.
