A collection of sparse Fourier transform codes developed by faculty at MSU. Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.)

Libraries for integration of atmospheric trajectories. Includes a basic trajectory integrator, contour advection codes and semi-Lagrangian tracer simulations.

ANT.1D is a stand-alone quantum transport code for essentially one-dimensional setups described by tight-binding or ab initio Kohn-Sham Hamiltonians obtained from other codes working with atomic basis sets (Gaussian, Crystal,SIESTA). Interfaces with Crystal and Gaussian codes are available. Electrodes are described either by nanowires of finite thickness or Bethe lattice electrodes.

The Lightweight Integrating Multiphysics Environment for coupling codes (LIME) is a small software package for creating multiphysics simulation codes. LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve different parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defined approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code. ...

The ESCL is a class library that can be used to develop electronic structure codes like those that are used in computational condensed matter physics. An object-oriented approach is suitable since real-world items like atoms and electrons are modeled.
