JUDI.jl
Julia Devito inversion
JUDI is a framework for large-scale seismic modeling and inversion and is designed to enable rapid translations of algorithms to fast and efficient code that scales to industry-size 3D problems. The focus of the package lies on seismic modeling as well as PDE-constrained optimization such as full-waveform inversion (FWI) and imaging (LS-RTM). Wave equations in JUDI are solved with Devito, a Python domain-specific language for automated finite-difference (FD) computations. JUDI's modeling operators can also be used as layers in (convolutional) neural networks to implement physics-augmented deep learning algorithms thanks to its implementation of ChainRules's rrule for the linear operators representing the discre wave equation. -

Hex
Hydrogen-Electron Collisions
A computer code for simulation of electron-hydrogen scattering. Contains three (more or less) finished sub-programs: (a) “hex-ecs” which solves the Schrödinger equation in the B-spline basis, (b) “hex-dwba” which computes scattering variables for high energies using the distorted wave Born approximation of the first order and finally (c) “hex-db” which is a user interface to a plain SQLite database, where the intermediate results are being stored, and which is used to extract derived quantities like a cross section from it. ... -

NEGF Nanoscale Thermoelectric Simulator
Electrical and thermal quantum simulations of 1D nanoscale materials.
This code simulates the 1D coupled transport in nanoscale materials. Both the electrical and thermal transport are simulated using a Non-equilibrium Green's function (NEGF) to solve the wave equation. The models handle the electron-phonon, electron-electron, and phonon-phonon interactions. The electrical model is a 1D effective mass description and the thermal model is a 1D atomistic description. This code was specifically designed to investigate nanoscale thermoelectrics. More specifically, highly confined superlattice structures, where the periodicity is on the order of 5nm. ... -
