Microscopic Patterns in the 2D Phase-Field-Crystal Model (2102.02338v1)
Published 3 Feb 2021 in math.NA, cs.NA, and math.DS
Abstract: Using the recently developed theory of rigorously validated numerics, we address the Phase-Field-Crystal (PFC) 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. We further address the dynamical relationships between the observed patterns for fixed parameters and across parameter space, then formulate several conjectures on the dynamical connections (or orbits) between steady states.
