Researchers at MIT have developed a machine learning framework to predict the thermal properties of materials much faster than existing methods. By using virtual node graph neural networks (VGNNs), the new approach can estimate phonon dispersion relations—critical for understanding heat movement in materials—up to 1,000 times faster than previous AI methods and 1 million times faster than traditional techniques. This innovation could lead to more efficient energy generation and better microelectronics by enabling rapid and accurate thermal property predictions.
