We perform high-precision calculations using the Stochastic Variational Method (SVM) in the explicitly-correlated Gaussian (ECG) basis to compute the energy spectra and stationary-state wavefunctions of quantum-mechanical few-body systems. These widely applicable techniques allow us to rigorously analyze few-body systems in a variety of problem domains across the physics and physical chemistry literature.
Our most recent application of SVM-ECG calculations has focused on the characterization of electron-hole interactions in 2D semiconductor materials.

We used symbolic algebra techniques to automatically derive linear multistep methods (LMMs) to solve systems of ordinary differential equations (ODEs). We also developed a suite of tools to characterize and compare these LMMs
Specific methods with a combination of good analytical and numerical characteristics were identified and published.
