Dear Michael,
Nothing has been released yet.
If you just want to do Coulomb blockade, I would go for Master/Lindblad equation
and for that you can use e.g. the qutip solver (
https://qutip.org) or even write your own.
(First construct the quantum dot empirically and calculate the parameters of the master/Lindblad equation with Kwant. Second use qutip to solve the latter).
If you want a realistic model that treats the electrostatic properly (i.e. the input is just the geometry of the gates + some material parameters), then you have to wait a bit for the PESCADO package that is a few months away
from its first release (you will still need a master equation solver eventually).
If you want the full thing (i.e. with Kondo effect) then the best method
but we’re still a long way from releasing an open source code
(The core of the algorithm, the « tensor cross interpolation " part will be released soon though, the package will be called Xfactorization or xfac).
Best regards,
Xavier
Dear Xavier,
Has there been any progress in Kwant's ability to model Coulomb blockade since this post? It's something that I'd be interested in modelling, in a similar setup to the one described by Jonathan.
All the best,
Michael
