Author(s): Péter Jeszenszki, Hongjun Luo, Ali Alavi, and Joachim Brand Exact diagonalization expansions of Bose or Fermi gases with contact interactions converge very slowly due to a nonanalytic cusp in the wave function. Here we develop a transcorrelated approach where the cusp is treated exactly and folded into the many-body Hamiltonian with a similarity transformati... [Phys. Rev.
