DeePTB

DeePTB#

DeePTB is an innovative Python package that uses deep learning to accelerate ab initio electronic structure simulations. It offers versatile, accurate, and efficient simulations for a wide range of materials and phenomena. Trained on small systems, DeePTB can predict electronic structures of large systems, handle structural perturbations, and integrate with molecular dynamics for finite temperature simulations, providing comprehensive insights into atomic and electronic behavior. See more details in DeePTB-SK: Nat Commun 15, 6772 (2024) and DeePTB-E3: arXiv:2407.06053.

DeePTB trains the model based on the Structure, Eigenvalues, Hamiltonian, Density matrix, and Overlap matrix from first-principles calcualtions. DeePTB team provides the interfaces dftio with other first-principles softwares. dftio fully supports the interfaces with ABACUS, and can transfer the Structure, Eigenvalues, Hamiltonian, Density matrix, and Overlap matrix from ABACUS into the format used in DeePTB.
