Dear Sir,
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.
Best Regards,
Zhang Bing
Hi,
First, thanks to the authors for opening kwant to the community.
In the kwant paper it is mentioned that "a few additional lines of code
allow us to parallelize the script for a multi-core workstation or cluster".
I was wondering if you could share any tip in this direction.
Best regards.
Luis.
Hello,
I messaged a coupled months back on a basic question. I have another one.
KWANT has been very useful to me so far, and I like to think I've made some
progress with it, however, I still occasionally am tripping up on basic
things. I'm sorry if the answer to this is obvious.
I am trying to create an SNS junction to study helical ABSs in a magnetic
field, but I'm having some basic problems implementing the magnetic field
in the code along with the Bogliubov de-Gennes equation. Using the
tutorials and paper as my guide, I'm defining a global method for the
hopping and have tried to use it in the system, without success. How would
I implement it with the hoppings with the superconductor formalism, with
separate leads for electrons and holes? Is there something I'm missing on
how to do it-you can't just use the magentic field as the hopping, as in
the examples. Would I just subtract it as a gauge from the Hamiltonian
diagonal entries, as you do analytically? Is there an example out there
for that?
At the moment, as a side question, when I try to simply to multiply the
magnetic field with 4t-mu, I'm getting a ValueError: that the hoppings then
do not match the dimensions of the onsite Hamiltonian. So I'm guessing
that's not the way of going about it.
Thank you.
