I had done most of the hard thinking when GPU accelerating the OBME calculation. The structure of the loops had to be slightly altered and I had to get rid of the $J$$M$$m^2$$m(m + 1)/2$$$ \lim_{x \rightarrow \infty} \frac{m(m + 1)}{2m^2} = \frac{1}{2} $$$M_\text{dim} = 6116$ text/html 2024-11-08T18:10:39+00:00 Anonymous (anonymous@undisclosed.example.com) https://thetechbasement.no/science:physics:nuclear-physics:shell-model:overview-of-effective-interactions?rev=1731089439&do=diff Overview of effective interactions In this article you'll find an overview of many effective interactions. My goal is to make nuclear shell model codes more transparent, easily accessible, and user friendly. Doesn't help that someone made a super performant code if it is not publicly available, difficult to obtain, and / or hard to use! Physicists are notorious when it comes to this, except maybe this one? \(n\)\(l\)\(j\)\(tz\)\(g_{s, p}, g_{s, n}\)\(g_s\)\(^{17}\)\(^{39}\)\(sd\)\(^{16}\)\(^{41… text/html 2024-11-14T05:18:51+00:00 Anonymous (anonymous@undisclosed.example.com) https://thetechbasement.no/science:physics:nuclear-physics:shell-model:so-what-is-the-one-body-transition-density?rev=1731561531&do=diff NB: The text is incomplete and I have to go through it thoroughly!
