1. Getting started

Firstly, you have to add an ssh key to your github account. To do so, just execute on the terminal:

$ ssh-keygen

And press enter to everything.

Then, copy the content on .ssh/id_rsa.pub into your ssh keys on GitHub.

Once you did that you only need to run:

$ git clone [email protected]:TsspGit/CodVid19_CIEMAT.git

And the project would be copied to your current folder.

2. Folders explanation

src/:

In this folder can be found the more general notebooks on ultracold atoms theory such as quasi-1D Harmonic Oscillator + Delta potential spectrum or a toy model of Landau Zener transitions.

utils/:

• atomic_units.py contains the values of the fundamental constants of the Hartee atomic units.
• VjtoIj.py python script to input the data as written in the papers and output the data as must be written in the codes. Run: ./VjtoIj.py and the code start to ask the parameters. Output: Intensities in W/cm2 and the trap length.
• Units.ipynb a python notebook seemly to VjtoIj.py. It contains the equations in LaTeX format.
• General_Figures Figures of the src/ notebooks.

convergence/:

• Convergence_With_Potential.ipynb this notebook uses two useful functions to read and plot the eigenvalues eassily, furthermore it presents an example of a well-convergenced execution.

out/:

Saved logs of otaold_2hm.csh and the scatlength vs potential parameter.

potentials/:

• potutils/ contains a function to read the potentials eassily.
• Li7Li7_potential071.ipynb an example of Li7-Li7 potential with parameter 071.
