Hi John,
When dealing with quantum dots, I think you're usually interested in
the quasi-adiabatic approximation, when only a few levels are ever
occupied, and dealing with the effective time-dependent Hamiltonian of
those levels. If this is indeed your case, I recommend to look at our
recent work (https://arxiv.org/abs/1909.09649), where we implement the
Lowdin partitioning algorithm for computing an effective few-level
Hamiltonian starting from the microscopic Kwant model. The associated
code is published on Zenodo.
Alternatively, if you want to simulate the complete time evolution of
the full wave function, there's the package t-kwant that is now being
prepared for release (https://gitlab.kwant-project.org/kwant/tkwant).
Let me know if that helps, and if you have any further questions.
Best,
Anton

To whom it may concern, I am a graduate student at the University of Illinois at Chicago (UIC) and I am interested in studying qubit manipulation in single and double quantum dots made from TMDCs. Specifically, I am interested in simulating a type of qubit/quantum dot configuration which was proposed in the following paper: https://iopscience.iop.org/article/10.1088/1367-2630/ab5ac9 I noticed that Kwant does seem to allow for time-dependent electric fields in its calculations but I wasn't sure if it could handle this specific type of problem.
What I would like to know is the following: 1. Is Kwant capable of simulating a quantum dot similar to the one proposed in the linked paper 2. If not, what kind of modifications would I need to make to the code to make it possible for it to accurately simulate the proposed structure
Thank you for your time, John Tiessen
