Alas, my computer broke down over Christmas, so I haven't been able to do any WL programming as of late. But I'm getting a Nvidia Jetson Nano this week, so it'll be interesting to see how it performs with Wolfram Engine ;)
I have helped my physicist friends release a package for evaluation of the bounce action with multiple scalar fields (related to cosmology and high energy physics) called FindBounce. If you are interested, please see this repository https://github.com/vguada/FindBounce. Any feedback is welcome.
@J.M.isinlimbo just curious - why suddenly override a suggested edit from 2017, especially if you're going to reapply the changes immediately afterward? mathematica.stackexchange.com/posts/37559/revisions
Like, I don't especially care about an edit from three years ago, but I got a reputation notice about a -2 from a site I'd never posted to so I got curious and checked what had happened ;)
