TranSIESTA School 2026

Technical University of Denmark, 9th - 13th November 2026

Topics covered (may be subject to changes):

• Usage of TranSIESTA/TBtrans and sisl.
• Correlated systems and the mean field Hubbard model.
• Single contacts by removal of periodic images.
• Modelling of extremely large systems with DFT precision.
• Manipulation of Hamiltonians by merging and creating real-space plots.

It will cost ~300 EUR to participate, paid in advance. This will cover lunches, coffee breaks and the conference dinner. One can sign up link to be given.

Registration

Registration has not started yet. A link will be provided as soon as it is made :)

Preparation training

Students are expected to have some experience with DFT codes and condensed matter physics at an introductory level.

Computer requirements

We expect students to come with their own laptops with a functional Linux or Mac operating system. Windows users may use WSL to get a Linux system.

Contact

If questions arise, please do not hesitate to bring them up on the sisl Discord channel. We encourage users to stay around the community at that channel.
