On the use of neural networks for full waveform inversion
Computer Methods in Applied Mechanics and Engineering, 2023 Neural networks have recently gained attention in solving inverse problems. One prominent methodology are Physics-Informed Neural Networks (PINNs) which can solve both forward and inverse problems. In the paper at hand, full waveform inversion is the considered inverse problem. The performance of PINNs is compared against classical adjoint optimization,

Gate‐Tunable Floquet Weyl Photon Emission from Topological Dirac Semimetal Cd3As2
Advanced Materials, EarlyView.We report experimental demonstration of Floquet band engineering in a 3D Dirac semimetal. Circularly polarized light breaks the time reversal symmetry and transforms Cd3As2 into a Floquet–Weyl phase, splitting Dirac nodes into chirality‐opposite Weyl nodes with nonzero Berry curvature.

Transfer Learning Enhanced Full Waveform Inversion*
2023 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2023 We propose a way to favorably employ neural networks in the field of non-destructive testing using Full Waveform Inversion (FWI). The presented methodology discretizes the unknown material distribution in the domain with a neural network within an adjoint optimization.

Full waveform inversion with combined misfit functions and application in land seismic data
Frontiers in Earth Science, 2023 Full waveform inversion reconstructs subsurface structures by matching the synthetic waveform to the observed waveform. Inaccuracy of the source wavelets can, thus, easily lead to an inaccurate model.
