Allows you to create well-defined and simple light-matter interaction energy diagrams. Include quantum states and photon energies (couplings) between states. Ideal for non-linear optics and light-matter interactions in general.
- This code was written using MATLAB (version 2020a). Download MATLAB on your computer or try MATLAB online
- Go to MATLAB File Exchange sign up/log in (https://www.mathworks.com/matlabcentral/fileexchange/). This community has tons of great MATLAB codes!
- Download the "arrows.m" code (script): François Beauducel (2021). ARROWS: generalized and vectorized 2-D arrows plot (https://www.mathworks.com/matlabcentral/fileexchange/37371-arrows-generalized-and-vectorized-2-d-arrows-plot), MATLAB Central File Exchange. Retrieved March 14, 2021.
- Once downloaded, copy this file to the MATLAB parent directory. On Windows, this is typically: C:\Users\YourUserName\Documents\MATLAB
- To make sure this was installed correctly, go to the MATLAB command window and type: arrows(1,1,1,1) , a plot of an arrow should be prompted
- Download my code on this repository: "light_matter_energy_level_diagram.m" and open it on MATLAB. Run the code and get a nice energy level diagram! (it should look like the "example.png" file)
- Modify the code to get the specific type of plot you are looking for (add photon couplings, make photons non-collinear, change colors, etc.)
