Surface Phase-Field-Crystal-Helfrich model for out-of-plane deformations in thin crystalline sheets with lattice mismatch
Emma Radice, Ingo Nitschke, Marco Salvalaglio +1
Thin, flexible crystalline sheets exhibit unique elastic properties due to their ability to undergo out-of-plane deformations. Understanding this behavior requires a description th…
Intrinsic grain-size gradients upon grain growth near a free surface
Jing Tang, Runlu Yan, Donglan Zhang +5
Grain growth fundamentally shapes the microstructure of crystalline materials upon annealing, affecting their overall mechanical and functional properties. Recently, it has been ra…

Maik Punke, Marco Salvalaglio
We present a MATLAB-based framework for two- and three-dimensional fast Fourier transforms on multiple GPUs for large-scale numerical simulations using the pseudo-spectral Fourier…
Shear-Coupled Grain Growth Statistics
Caihao Qiu, David J. Srolovitz, Gregory S. Rohrer +2
Grain growth (GG), driven by grain boundary (GB) migration, is a fundamental mechanism of microstructural evolution in polycrystalline materials. GB migration is frequently accompa…
Dislocation dynamics on deformable surfaces
Marcello De Donno, Luiza Angheluta, Marco Salvalaglio
We develop a fully coupled theoretical description of dislocation dynamics on deformable crystalline surfaces, using continuum modeling and the amplitude-phase-field crystal (APFC)…
Grain-Growth Stagnation from Vacancy-Diffusion-Limited Disconnection Climb
Maik Punke, Abel H. G. Milor, Marco Salvalaglio
Grain growth in polycrystals typically stagnates at long times. We identify disconnection climb, limited by vacancy diffusion, as a fundamental microscopic mechanism underlying thi…
A topological approach to the Cahn-Hilliard equation and hyperuniform fields
Abel H. G. Milor, Otto Sumray, Heather A. Harrington +2
Hyperuniform structures are disordered, correlated systems in which density fluctuations are suppressed at large scales. Such a property generalizes the concept of order in pattern…
Solid-State Dewetting of Polycrystalline Thin Films: a Phase Field Approach
Paul Hoffrogge, Nils Becker, Daniel Schneider +3
Solid-state dewetting is the process by which thin solid films break up and retract on a substrate, forming nanostructures. While dewetting of single-crystalline films is understoo…
Modeling dislocations in quasicrystals through amplitude equations
Marcello De Donno, Luiza Angheluta, Marco Salvalaglio
Quasicrystals (QCs) are a class of aperiodic ordered structures that emerge in various systems, from metallic alloys to soft matter and driven non-equilibrium systems. Within a mes…
Unidirectional motion of topological defects mediating continuous rotation processes
Marisel Di Pietro Martínez, Luke Alexander Turnbull, Jeffrey Neethirajan +9
Topological defects play a critical role across many fields, mediating phase transitions and macroscopic behaviors as they move through space. Their role as robust information carr…
Phase-field Modelling of Anisotropic Solid-State Dewetting on Patterned Substrates
Emma Radice, Marco Salvalaglio, Roberto Bergamaschini
We present a phase-field model for simulating the solid-state dewetting of anisotropic crystalline films on non-planar substrates. This model exploits two order parameters to trace…
Why Grain Growth is Not Curvature Flow
Caihao Qiu, David J. Srolovitz, Gregory S. Rohrer +2
Grain growth in polycrystals is traditionally considered a capillarity-driven process, where grain boundaries (GBs) migrate toward their centers of curvature (i.e., mean curvature…
Inferring traits of hyperuniformity from local structures via persistent homology
Abel H. G. Milor, Marco Salvalaglio
Hyperuniformity refers to the suppression of density fluctuations at large scales. Typical for ordered systems, this property also emerges in several disordered physical and biolog…
