Abstract

We derive an integral equation describing N two-dimensional bosons with zero-range interactions and solve it for the ground state energy B N by applying a stochastic diffusion Monte Carlo scheme for up to 26 particles. We confirm and go beyond the scaling B N ∝ 8.567N predicted by Hammer and Son (2004 Phys. Rev. Lett. 93 250408) in the large-N limit.
