We demonstrate many-body multifractality of the Bose-Hubbard Hamiltonian'sground state in Fock space, for arbitrary values of the interparticleinteraction. Generalized fractal dimensions unambiguously signal, even forsmall system sizes, the emergence of a Mott insulator, that cannot, however, benaively identified with a localized phase in Fock space. We show that thescaling of the derivative of any generalized fractal dimension with respect tothe interaction strength encodes the critical point of the superfluid to Mottinsulator transition, and provides an efficient way to accurately estimate itsposition. We further establish that the transition can be quantitativelycharacterized by one single wavefunction amplitude from the exponentially largeFock space.
