Physical reflections of prime-number distribution

Question

Not a purely mathematical question:

I have read somewhere that Atomic Orbital is closely related to the distribution of prime numbers, but I am unable to find any reference to that.

Can someone please explain this relation (if it even exists)?

Also, what other physical reflections of prime-number distribution are known?

Thanks
