Repository for Correlations of spin splitting and orbital fluctuations due to 1/f charge noise in the Si/SiGe Quantum Dot

Structure of the repository:

• Code: Contains the code for the simulation of the charge noise affecting a quantum dot in a Si/SiGe structure. It uses the data from the Data folder.
• Data: Contains the data generated by the COMSOL simulation.
• Figures: Contains additonal figures generated during development of the code.
• COMSOL: Contains the COMSOL simulation files.

How to run the code:

• The code is written in Python 3.7. To run the code, you need to have the following packages installed:
  • numpy
  • matplotlib
  • scipy

The code is written in the form of a Jupyter notebook. There are seven notebooks, each corresponding to a different figure:

• fig1.ipynb - figure 1
• fig23.ipynb - figure 3
• fig4.ipynb - figure 4
• 'linearity_check.ipynb' - linearity test
• 'get_orbital_sigmas.py' - script used in fig23.ipynb
• 'dx_dy_gen.ipynb' - wrapper that generates shifts of wavefunction from comsol data
