Hello! I read a bit about decoherence lately (I made a post few weeks ago about it and got some reading suggestions) and I would like to try to apply it to a practical situation I need, which is a Penning trap with a single ion at the center. For now I would like to account just for the decoherence due to the black body radiation and as far as I understand the spin-boson model would be the right one for this (at least to start with). However that involves certain coupling constant which I am not sure how to approximate for my given setup. Can someone point me towards some reading about this or previous calculations made for a (cylindrical) Penning trap such that I can start from there? Thank you!
