Frustrated magnets in the limit of infinite dimensions: Dynamics and disorder-free glass transition
We study the statistical mechanics and the equilibrium dynamics of a system of classical Heisenberg spins with frustrated interactions on a d -dimensional simple hypercubic lattice, in the limit of infinite dimensionality d -> infinity . In the analysis we ...
Amer Physical Soc2024Atomic-level structure determination of amorphous molecular solids by NMR
David Lyndon Emsley, Arthur César Pinon, Pinelopi Moutzouri, Manuel Cordova
Structure determination of amorphous materials remains challenging, owing to the disorder inherent to these materials. Nuclear magnetic resonance (NMR) powder crystallography is a powerful method to determine the structure of molecular solids, but disorder ...
Berlin2023Electronic Coupling of Metal-to-Insulator Transitions in Nickelate-Based Heterostructures
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
In rare earth nickelates, the metal-to-insulator transition observed as a function of temperature can be described using an electronic and a structural order parameter. The electronic one is linked to the electronic disproportionation observed below the tr ...
WILEY2023Decoding the Mechanisms of Phase Transitions from In Situ Microscopy Observations
Vasiliki Tileli, Reinis Ignatans
Analysis of the temperature- and stimulus-dependent imaging data toward elucidation of the physical transformations is an ubiquitous problem in multiple fields. Here, temperature-induced phase transition in BaTiO3 is explored using the machine learning ana ...
WILEY-V C H VERLAG GMBH2022VO2:Ge based thermochromic solar absorber coatings
Anna Krammer, Josef Andreas Schuler
Flat plate solar collectors face the problem of overheating and the ensuing high thermal stresses and general collector damage lead to high maintenance costs. To address this challenge, absorber coatings with a passive optical switch at critically high ope ...
ELSEVIER2022Phase and microstructure selection in peritectic alloys under high G-V ratio
Wilfried Kurz, Stéphane Dobler
A new model for the case of a superposition of a phase transformation and a microstructure transition from columnar plane front to equiaxed dendritic growth for peritectic alloys is presented. This model is applied to Fe-Ni alloys where a phase transition ...
WALTER DE GRUYTER GMBH2022Stability of hydrate assemblages and properties of cementitious systems with higher alumina content
Two low CO2 cement systems are investigated: one made with the use of supplementary cementitious materi-als (SCMs) (metakaolin and limestone) and the other an alternative binder, calcium sulfoaluminate cement (CSA). These two low CO2 cements contain a simi ...
EPFL2021Local excitations in amorphous solids
Amorphous solids are structurally disordered. They are very common and include glasses, colloids, and granular materials, but are far less understood than crystalline solids. Key aspects of these materials are controlled by the presence of excitations in w ...
EPFL2021Fabrication of micrometer-sized drops as templates for particles
Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...
EPFL2021A Statistical Physics approach to a multi-channel Wigner spiked model
Emanuele Mingione, Diego Alberici
In this letter we present a finite temperature approach to a high-dimensional inference problem, the Wigner spiked model, with group-dependent signal-to-noise ratios. For two classes of convex and non-convex network architectures the error in the reconstru ...
