I am a PhD student of Hong Kong University of Science and Technology. I
want to use KWANT to caculate Hall resistance of a Hall bar structure.We
can get the conductance between 6 electrodes, but how to get hall
resistance? Can you give me some help? Thank you very much.
I am in a fix
(i) as to how to draw the VD- ID, VG-ID etc. by kwant coding. I am to some extent clear to
get those relations from the back calculations of G= ID/VG and the current expression in
terms of the G. Finding G by kwant they may be found out. But, I like very much a direct
coding technique to get these curves.
(ii) as to how to visualize a 3D graphics of nanostructure like QWR, QD which I visualize in
2D without problem.
Please help me.
I’m posting this here since some people may be interested to play
around with Kwant and the following:
Intel has just released the “Intel Distribution for Python”.
That’s an anaconda-based variant of the scientific Python stack
that has been optimized with Intel’s libraries like MKL and TBB.
It seems that Intel’s “distribution” can be installed as a single
big download on Linux, Mac & Windows.
Building Kwant on top of this “distribution” should work just fine
(without MUMPS). It should be also possible to use it with MUMPS.
What’s perhaps the most interesting is that the “distribution”
includes Intel’s MKL which in term includes a variant of the
PARDISO direct linear solver. If someone is interested in working
on adding a MKL PARDISO solver to Kwant, the new “distribution”
could be an easy way to install all the required bits in one go.
It would be also interesting to see how much faster Kwant is with
MUMPS+MKL and PARDISO+MKL, and how much better it scales on
Please let us know of any results with regard to this.
