Atom-Atom scattering with Numerov method and external fields

This example illustrates the use of the qdyn library to simulate multi-channel atom-atom scattering with different type of couplings and with external fields. The scattering problem is solved with the renormalised Numerov method.

Running the Example

You must compile the example by running make. Then, run the resulting numerov_examples program by executing

./numerov_examples

or alternatively

::

./numerov_examples | tee out.dat

if you want to save the output in a file. This will run the simulation for different scattering problems one after another.

The example consists of four parts:

  • Part 1: Sr2 scattering in non-resonant laser field. runfolder: run_numerov_in_field

  • Part 2: Retrieving the scattering wavefunction runfolder: run_numerov_psi

  • Part 3: Photoassociation rates for Rb scattering runfolder: run_numerov_PA

  • Part 4: Radiative association for Yb-Li scattering runfolder: run_numerov_RA

Results are saved in the corresponding runfolders.

For cleaning up the example run make clean.
