Using quantum Monte Carlo methods for calculating few and many-body systems

  Hilla Deleon  ,  Francesco Pederiva  

The behavior of an N-body helium droplets systems is studied using diffusion Monte Carlo (DMC). We are using two- and three-body pionless effective field (πEFT) potential  al leading-order (LO) calibrated from the dimer and trimer  binding energies  to predict the N-body (up to 100-body) binding energies as a function of the ultra-violet cutoff, Λ.
