A hyperbolic singularity in the wave-function of $s$-wave interacting atomsis the root problem for any accurate numerical simulation. Here we apply thetranscorrelated method, whereby the wave-function singularity is explicitlydescribed by a two-body Jastrow factor, and then folded into the Hamiltonianvia a similarity transformation. The resulting non-singular eigenfunctions areapproximated by stochastic Fock-space diagonalisation with energy errorsscaling with $1/M$ in the number $M$ of single-particle basis functions. Theperformance of the transcorrelated method is demonstrated on the example ofstrongly correlated fermions with unitary interactions. The current methodprovides the most accurate ground state energies so far for three and fourfermions in a rectangular box with periodic boundary conditions.
