The Kwant project is an international collaboration. Everybody is welcome to participate in the community by asking and replying to questions, reporting bugs, providing suggestions, and contributing to the code and documentation.
A list of Kwant authors is included in the documentation. Please only contact the authors directly for matters that cannot be discussed in public on one of the mailing lists.
The kwant-discuss mailing list is the main public communication platform for anything related to Kwant: questions, discussions, development, and announcements. (Bug reports may be also sent, but the preferred way is described further below on this page.) You can use it in various ways:
to subscribe and receive new messages by email: either use the form on the kwant-discuss info page or simply send a message to email@example.com. (The subject and content are ignored and may be empty.) To unsubscribe, either use the form at the bottom of the info page, or send any message to firstname.lastname@example.org.
You may follow the list through a web interface that also provides a RSS feed: kwant-discuss on Mail-archive.
Whether you are subscribed or not, you may post on the list simply by sending email to email@example.com.
Please do not hesitate to join the discussion. It’s easy to reply to a posting even if you are not subscribed (or receiving digests): (1) open the article in the mail-archive web interface, (2) click on the button “Reply via email to” at the bottom of the page, (3) add the above list address under "CC".
The Kwant development mailing list has been retired in 2019. Please use the main list instead, or the other communication channels listed below (chat and gitlab). The archives of kwant-devel remain searchable:
Announcements mailing list
This read-only list is reserved for important announcements like new releases of Kwant. Only a few messages will be sent per year. These announcements will be also posted on the main mailing list, so there is no need to subscribe to both lists. We recommend every user of Kwant to subscribe at least to this list in order to stay informed about new developments.
- View archives: kwant-announce on Mail-archive. Mail-archive provides RSS feeds.
- There are two ways to subscribe: either use the form on the kwant-announce info page or simply send any message to firstname.lastname@example.org. (The subject and content are ignored and may be empty.) To unsubscribe, either use the form at the bottom of the info page, or send any message to email@example.com.
The Kwant developer chat is accessible to the community via Gitter. Come say hi if you would like to get involved with developing Kwant!
The Kwant project runs a gitlab instance that hosts the main Kwant code repository as well as the repositories of related projects. The gitlab instance is used for reporting bugs (see next section) and development
If you encounter a problem with Kwant, first try to reproduce it with as simple a system as possible. Double-check with the documentation that what you observe is actually a bug in Kwant. If you think it is, please check the list of known bugs in Kwant. It may be also a good idea to search or ask on the general mailing list. (You can use the search box at the top of this page.)
If after checking you still think that you have found a bug, please add it to the above-mentioned list of bugs by creating an issue with the “bug” label. A useful bug report should contain:
- The versions of software you are using: Kwant, Python, operating system, etc.
- A description of the problem, i.e. what exactly goes wrong. This should include any relevant error messages.
- Enough information to reproduce the bug, preferably in the form of a simple script.
