Description
Neural-network quantum states have been developed as an efficient method for solving quantum many-body problems, not only in lattice systems but also in systems of particles in continuous space. Here, we apply this approach to strongly interacting few-body problems in continuous space at unitarity: the Efimov states and associated few-body bound states. We obtain the ground and first excited states of few bosons with a projection method, and a mass-imbalanced fermionic system consisting of two identical fermions and a third particle. The obtained energies of the ground and first excited states of these systems agree well with previously reported results. Furthermore, the proposed approach also reproduces the discrete scale invariance between the ground and first-excited states and the critical-mass behavior in mass-imbalanced fermionic systems. Our method can be straightforwardly applied to a broad class of strongly correlated few-body problems in continuous space.
