Non-trivial saddles in microscopic description of black holes

open access: yesJournal of High Energy Physics
Non-trivial gravitational saddles have played a key role in the island proposal for the black hole information paradox. It is worth asking if non-trivial saddles exist in microscopic descriptions of black holes.
