Dear colleagues, It is our pleasure to announce the first release of the free software TKwant for time-resolved quantum transport. An introduction to TKwant can be found in TKwant paper: https://arxiv.org/abs/2009.03132 https://arxiv.org/abs/2009.03132 . The software itself and its tutorials can be found here: https://tkwant.kwant-project.org https://tkwant.kwant-project.org/ . TKwant is an extension of Kwant (http://kwant-project.org http://kwant-project.org/) to time-dependent problems. A system is defined in TKwant in the same way as in Kwant except that some terms in the Hamiltonian may depend on the time parameter. Any system that can be studied in Kwant (e.g. graphene, metals, superconductors, topological insulators, magnetic systems, 2DEGs, any combination of the above and more) can be extended to TKwant. Typical problems where TKwant can be used include the propagation of voltage pulses, spectroscopy of interferometers, Floquet topological insulators, time resolved Andreev reflection and more. We had a lot of fun in making this package and we hope that many of you will have a lot of fun using it. Kind regards, Xavier and Thomas on behalf of TKwant authors. ___________________________________ Xavier Waintal Research Director University Grenoble Alpes CEA-IRIG, PHELIQS, 17 rue des Martyrs, 38054 Grenoble CEDEX 9, FRANCE Tel: 33 (0)4 38 78 03 27 email: xavier.waintal@cea.fr mailto:xavier.waintal@cea.fr http://www.pheliqs.fr/en/Pages/Portrait/Xavier-Waintal.aspx http://www.pheliqs.fr/en/Pages/Portrait/Xavier-Waintal.aspx http://kwant-project.org http://kwant-project.org/ https://tkwant.kwant-project.org https://tkwant.kwant-project.org/ ___________________________________
