A Novel NPT Thermodynamic Integration Scheme to Derive Rigorous Gibbs Free Energies for Crystalline Solids
Karel L. K. De Witte, Tom Braeckevelt, Massimo Bocus +2
Thermodynamic Integration (TI) is the state-of-the-art computational technique for accurate Gibbs free energy predictions of solids. Conventional TI schemes start from an NVT harmo…
The effect of the A-site cation on the phase transition temperature of metal halide perovskites
Tom Braeckevelt, Sander Vandenhaute, Sven M. J. Rogge +2
A key challenge for the practical application of metal halide perovskites (MHPs) is the instability of the desired perovskite phase relative to the optically non-active phase.…
Orb-v3: atomistic simulation at scale
Benjamin Rhodes, Sander Vandenhaute, Vaidotas Å imkus +4
We introduce Orb-v3, the next generation of the Orb family of universal interatomic potentials. Models in this family expand the performance-speed-memory Pareto frontier, offering…
Cluster-based machine learning potentials to describe disordered metal-organic frameworks up to the mesoscale
Pieter Dobbelaere, Sander Vandenhaute, Veronique Van Speybroeck
Metal-organic frameworks (MOFs) are highly interesting and tunable materials. By incorporating spatial defects into their atomic structure, MOFs can be finetuned to exhibit precise…
Rare Event Sampling using Smooth Basin Classification
Sander Vandenhaute, Tom Braeckevelt, Pieter Dobbelaere +2
The efficiency of atomic simulations of materials and molecules can rapidly deteriorate when large free energy barriers exist between local minima. We propose smooth basin classifi…
