I am trying to simulate the optical broadening of a Rydberg gas in an external magnetic field gradient. I have been trying to find ideas on how to approach this for quite some time, but I am still clueless. Do you have any tips on how you would approach this problem? If COMSOL is not actually suited to solve this, what other software could you recommend? I would be really glad for any help.

Hello Ria,

To help answer your question, readers of this Discussion Forum need to know what specific mathematical equations you have determined need to be solved, because that's basically what COMSOL does: solve equations. Unless we know what equations you wish to solve, we can't really tell you whether, or how, to use COMSOL software to tackle the problem, at least not without running the risk of pointing you in the wrong direction. For example, it would be interesting to know whether the external magnetic field is known to you a priori or whether it needs to be computed, and how you would like to relate that field to the spectral broadening.

It would also be helpful if you could describe what geometry you would like to solve those equations over. This could help determine if your goals are realistic. Sometimes people who are new to modeling expect to be able to solve problems that are beyond the reach of existing computers. We may be able to tell you in you are in that territory if we knew more about your project.

Best,

Jeff
