Hi Bjarke, Tutorial seems to be the best way to go. We're planning to set up a wiki on the kwant website in the near future, with the aim of providing a broader and more recent collection of code examples. So please feel free to make such a tutorial and share — it'll go to the wiki. Best, Anton PS please use 'reply all' in order for your emails to also be sent to the mailing list.

Hi Anton,

I imagine something like:

kwant.lattice.TMD - build the TMD lattice, consisting of the hexagonally packed metal atoms sandwiched between the two layers of chalcogen atoms.

Any maybe a set of predefined hopping constants for the most popular TMDs, such as MoS2 and WS2, to get users started.

Or maybe it would be fine to simply add it as an exercise or tutorial =)

Best, Bjarke

Hi Bjarke,

Thanks for your interest. What would such a system-specific builder do?

Best, Anton

Hi all!

Seeing as how useful Kwant is for graphene, along with the rising interest in transition metal dichalcogenides, would it be possible to add a default builder for such crystals?

Thanks!

Best, Bjarke
