# DeepErwin

DeepErwin is python package that implements and optimizes wave function models for numerical solutions to the multi-electron Schrödinger equation.

DeepErwin is based on JAX and supports:
- Optimizing a wavefunction for a single nuclear geometry
- Optimizing wavefunctions for multiple nuclear geometries in parallel, while sharing neural network weights across these wavefunctions to speed-up optimization
- Using pre-trained weights of a network to speed-up optimization for entirely new wavefunctions
- Using second-order optimizers such as KFAC or L-BFGS 

A detailed description of our method and the corresponding results can be found in our recent [arxiv publication](https://arxiv.org/pdf/2105.08351.pdf). When you use DeepErwin in your work, please cite:
