Kwant extensions
================
Going beyond the core package, there are several tools that extend Kwant in useful ways.
You can check these out below.
If you have some re-usable code that you think would be useful to the wider Kwant community,
post to the `Kwant development mailing list `_ with a
link to the code and a couple of sentences describing it, and we'll add it to this page.
Semicon: k·p simulations made easy
----------------------------------
**Get the code**: https://gitlab.kwant-project.org/r-j-skolasinski/semicon
A package of tools for doing k·p simulations. Contains: model definitions, material parameters,
and helper functions for generating template Kwant systems.
Generating quasicrystals
------------------------
**Get the code**: https://arxiv.org/src/1510.06035v2/anc/quasicrystal.py
Code for reproducing numerics from the paper "`Aperiodic Weak Topological Superconductors `_"
by Fulga et al.
Contains functionality for building 2D Ammann-Beenker tilings, an example of a quasicrystal, and
Kwant systems constructed from such tilings.
Time-dependent transport
------------------------
**Get the code**: https://gitlab.kwant-project.org/jbweston/tkwant
A package for defining time-dependent systems with Kwant, and calculating
time-dependent quantities. Details of the algorithm can be found in the
following two papers:
+ `Towards realistic time-resolved simulations of quantum devices `_
+ `Numerical simulations of time resolved quantum electronics `_
