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