Quantum Monte Carlo methods for few and many-body physics

  Hilla De-Leon  ,  Francesco Pederiva  

We study the behavior of an N-body helium drops systems using diffusion Monte Carlo (DMC).
We are using two- and three-body pionless effective potential calibrated from the dimer
and trimer binding energies to predict the N-body binding energies as a function of the ultraviolet cutoff, $Lambda$.
