Marco Salvalaglio

I am honored to have contributed to practically "taking care of the #thermodynamic #limit". Indeed, one of the best pastas I have ever eaten, in one of the best atmospheres ever (the glorious WG of Bautzi 27 in Dresden).

Extremely well-deserved for a team of brilliant young scientists and wonderful people, including some true #friends. I’m sure there’s much more to come from them. Keep an eye out!

Modeling dislocations in quasicrystals through amplitude equations Quasicrystals (QCs) are a class of aperiodic ordered structures that emerge in various systems, from metallic alloys to soft matter and driven non-equ…

When crystals lose periodicity, dislocations gain complexity; Our study reveals an interesting hierarchy of defects in quasicrystals. With Marco Salvalaglio @marcosave.bsky.social and @Marcello De Donno

Phase field #numerical #simulations well reproduces key features from #Molecular #Dynamics simulations and experimental GB velocity–curvature distributions.

Disconnection-mediated migration of interfaces in microstructures: I. continuum model A long-standing goal of materials science is to understand, predict and control the evolution of microstructures in crystalline materials. Most micros…

To show this point, we extended a shear-coupled interface migration model www.sciencedirect.com/science/arti...) to full microstructures with the aid of a #multi-phase-field approach.

Grain growth is typically modeled as driven by GB energy reduction, but recent #simulations and #experiments show this is overly simplistic, even when accounting for anisotropies in mobility and GB energy. Shear-coupled GB migration allow for reconciling recent evidence.

We discuss the key role of shear deformation accompanying grain boundary (GB) migration (shear coupling) in driving #microstructure #evolution (grain growth) in single-component #polycrystals.

Why #grain #growth is not curvature flow, published today in PNAS!

“Anerkennung als Ansporn” Verleihung der Heinz Maier-Leibnitz-Preise »Aufmerksamkeit für herausragende Forschungsleistungen in frühen Karrierephasen ist das Hauptmotiv dieses Preises, der außergewöhnliche Güte und Originalität auszeichnet und ermutigen soll, den eingeschlagenen wissenschaftlichen Weg selbstbewusst weiterzuverfolgen.« Zitat DFG-Generalsekretärin Dr. Heide Ahrens

Erfolge in der Wissenschaft müssen auch gefeiert werden – und das haben wir bei der Verleihung der Heinz Maier-Leibnitz-Preise 2025 getan. 10 DFG-geförderte Forscher*innen haben sich in ihrem jeweiligen Fach verdient gemacht und wurden nun von DFG-Generalsekretärin Heide Ahrens in Berlin gewürdigt.

We applied the recently developed mesoscale field theory of quasicrystals to the study dislocations in aperiodic lattices. We found relevant differences with crystalline counterparts and delivered a versatile tool to study such dislocations! ⬇️ @luizaangheluta.bsky.social @tudresden.bsky.social

Deeply honoured for this award by the @dfg.de! Grateful to all the amazing colleagues, collaborators, and mentors who have contributed along the way. Huge thanks to my team and the unwavering support at @tudresden.bsky.social! #HML2025

Many thanks for all your support @humboldt-foundation.de!

#Multiscale #frameworks for simulating material properties typically couple different methods or use #coarse-graining to bridge scales efficiently. Here, we blended both approaches, solving phase field crystal eqs. at defects and interfaces 🔍 while solving its coarse-grained formulation elsewhere 🌐

Hybrid-PFC: Coupling the phase-field crystal model and its amplitude-equation formulation The phase-field crystal (PFC) model describes crystal structures on diffusive timescales through a periodic, microscopic density field. It has been pr…

We recently developed a new framework to perform diffusive-timescale simulations of crystals with microscopic resolution at defects and interfaces and coarse resolution elsewhere -- Paper out (open access) in #CMAME: www.sciencedirect.com/science/arti...

Thanks everyone for the immense interest and great feedback on our preprint! We are super happy (and a bit shocked) that a simple project developed among friends had such a resonance ending up in the New York Times and BBC!

@ivanditerlizzi.bsky.social @vicioms.bsky.social @dmbusiello.bsky.social

P.S. Having attended the first edition as a student, I can say it was a truly transformative experience. I'm looking forward to join it as a lecturer this time!

This summer school offers: (1) Reviews of the fundamentals of phase-field modeling; (2) Applications across diverse fields (e.g. microstructure evolution, multi-phase flow, fracture, soft matter, and biophysics); (3) An inspiring academic environment in a historic alpine setting.

🚨 The 4th edition of the Summer School on Phase-Field Models for the Evolution of Complex Structures will take place this year from September 15th to 26th in the picturesque village of Peyresq, southern France 🌄

A 'tribute to Keith Haring' (from 2021, Altana Gallery Dresden) out of hyperuniform structures (studied here doi.org/10.1103/Phys...). Copies are being shown around (GAMM 2023, Uni. Firenze, TU-Dresden) - now also under this blue sky!

Great collaboration between friends and colleagues at
@tudresden.bsky.social , University of Oslo and @oaklandu.bsky.social !

Thanks to this approach, we uncovered how small-angle grain boundaries fundamentally differ from their classical crystalline counterparts.

Importantly, we obtain direct access to defects! see the GIF above -- classical density-wave representation (left) and our mesoscale description (right).

We published (open access) in Physical Review Research
@apsphysics.bsky.social a Mesoscale field theory unifying the description of growth, elasticity, and defects in hashtag quasicrystals.
