I wasn't aware of this until very recently, when i casually read this article about Ramanujan expressions for modular forms (which are a form of holomorphic functions that leave invariant certain lattices, and are extensively studied for their number-theoretic applications). Apparently there is something called "modular black holes" which i don't have the faintest idea what is about, but it mentions that they are thermodynamically close to normal black holes, so they can be used to compute certain scrambling functions of the event horizon degrees of freedom
I would rather have someone provide an authoritative answer mentioning more details about this, as my ramblings are more or less extracted unmodified from the article. I hope someone that really understand about this gets annoyed enough by my answer and provides a real one.
