You might find this article by Michael Nielsen interesting: https://augmentingcognition.com/ltm.html

In particular I liked the section partway* through the article where he talks about using Anki to get up to speed on the AlphaGo paper for an article he was writing for Quanta.

* Do a Ctrl-F for "AlphaGo"

He also writes here about how to use spaced repetition to see through a piece of mathematics: https://cognitivemedium.com/srs-mathematics
