An activation-relaxation technique study of two-level system impact on internal dissipation using DFT-based moment tensor potential
Renaude Girard, Carl Lévesque, Normand Mousseau +1
We use a recently-developed machine-learned Moment Tensor Potential (MTP) trained on data generated with the density functional theory (DFT) and tailored to amorphous silicon coupl…

Amorphous silicon structures generated using a moment tensor potential and the activation relaxation technique nouveau
Karim Zongo, Hao Sun, Claudiane Ouellet-Plamondon +2
Preparing realistic atom-scale models of amorphous silicon (a-Si) is a decades-old condensed matter physics challenge. Herein, we combine the Activation Relaxation Technique nouvea…

Is the Future of Materials Amorphous? Challenges and Opportunities in Simulations of Amorphous Materials
Ata Madanchi, Emna Azek, Karim Zongo +3
Amorphous solids form an enormous and underutilized class of materials. In order to drive the discovery of new useful amorphous materials further we need to achieve a closer conver…
