Dear users of Kwant, We are pleased to announce the publication of the Kwant paper as New J. Phys. 16, 063065 (2014). In the published version we put Kwant in a broader context, motivate its design more clearly, and provide a real-world-research usage example. http://downloads.kwant-project.org/doc/kwant-paper.pdf We have also prepared a short video that demonstrates the use of Kwant directly. We invite you to relay the following link to anyone who may be interested: http://kwant-project.org/doc/kwant-screencast-2014 On a final note, Kwant 1.0.1 has been released. This is a maintenance release that fixes several minor bugs in Kwant 1.0.0. If you are not experiencing any technical problems with Kwant, you may choose to simply skip this upgrade. A list of all the changes in 1.0.1 is available at http://git.kwant-project.org/kwant/log/?h=v1.0.1 On Linux systems where Kwant has been installed in the standard way (apt-get), the upgrade to 1.0.1 should be performed as a part of a regular system upgrade. Windows and Mac users who want to upgrade need to re-install Kwant. See below for Mac upgrade instructions. Best wishes on behalf of all Kwant authors, Christoph Groth ---------------------------------------------- To upgrade kwant in macports, do sudo port upgrade py27-kwant (or py26-kwant, depending on whether you are using python 2.6 or 2.7). Follow the instructions for additional commands you have to execute. To upgrade Mac homebrew, some extra steps are needed because of some recent internal changes in homebrew. To upgrade kwant safely, do brew uninstall scipy numpy matplotlib kwant brew uninstall mumps_seq metis4 scotch5 gfortran brew update brew install gcc pip install python-dateutil brew install numpy scipy matplotlib brew install kwant For future updates of kwant, a simple "brew upgrade kwant" should be sufficient.
