A neat solution for hydrodynamic heat transport

In a new article in Physical Review Letters, MARVEL scientists from the THEOS lab at EPFL have made a leap forward in modelling and explaining phonon hydrodynamics, a heat conduction regime where heat flows like water in a pipeline. Their brand new mathematical description makes the phenomenon easier to test experimentally and clarifies the physics behind it. When applied to the in-plane section of graphite at a temperature of 70 K, it also points to a bizarre phenomenon that can emerge with hydrodynamic transport and by which heat can flow in reverse, from a colder region towards a hotter one. Being able to insert such a system into consumer electronics products would have huge applications, for example hydrodynamic heat management could help prevent batteries or other devices from overheating.

There’s an app for that: atomistic materials calculations made more accessible by the AiiDAlab Quantum ESPRESSO app

Powerful atomistic simulation tools have transformed materials research, but their complexity still limits who can use them and how easily results can be reproduced: a gap that a new web-based app now helps close. The AiiDAlab Quantum ESPRESSO app, described in a recent publication in npj Computational Materials, can run not only isolated calculations but also complete, end-to-end computational workflows involving multiple passages over several different materials, lowering the barrier for both experimentalists and computational experts. This is achieved through the tight integration of the widely-used Quantum ESPRESSO simulation software package with the AiiDA engine, a workflow-management system to help automate complex simulations in materials science and a core pillar of NCCR MARVEL, which has provided substantial support to its development alongside contributions from the broader community.

A new reference model for machine-learning–driven materials discovery

Researchers at EPFL’s Laboratory of Computational Science and Modeling (COSMO) have reached a significant milestone in material science, reaching the top position on Matbench Discovery, the leading benchmarking platform for machine-learning interatomic potentials.  The achievement was made possible by PET-OAM-XL, a new model, which builds on the foundations laid by the recently published PET-MAD model. 

Interviews with Giovanni Pizzi, Virginie de Mestral, Xingao Gong, Nicola Marzari

During the Psi-k 2025 that took place from 25 to 28 August 2025 in Lausanne, we interviewed several MARVEL members or top experts in computational materials science and asked them how they see the future of the field. Over the past few months we have been publishing the resulting interviews that present a range of diverse perspectives on the challenges and opportunities that await the community. The interviews are also an opportunity to assess the impact of MARVEL and its impact on the field overall. This month we complete the series with the interviews with MARVEL members Giovanni Pizzi from PSI and Virginie de Mestral from ETH Zurich, with the Funan University professor Xingao Gong, and with MARVEL director Nicola Marzari. All the interviews are collected in a playlist on the Materials Cloud YouTube channel.
