Ted Chiang-esque books

I am utterly obsessed with Ted Chiang but I realised today that I’ve read all his books and thats not enough. The problem is that I’ve found difficulty finding books that hold Chiangs style that I like, math/conceptual based science fiction in a really smart and simple way. I have a few Vonnegut books which I also adore, but I’m looking for more books in this genre, short stories are also a plus!
