Fermion Monte Carlo calculations of liquid 3He
- 27 Downloads
Methods and results for calculations of the ground state energy of the bulk system of 3He atoms are discussed. Results are encouraging: we believe that they demonstrate that our methods offer a solution of the “fermion sign problem” and the possibility of direct computation of many-fermion systems with no uncontrolled approximations. Although the method is still rather inefficient compared to variational or fixed-node methods, we have been able to obtain useful answers.
