- 論文の詳細を見る
The effective potential method is proposed in the path integral Monte Carlo calcula-lion for many-body system interacting with two-body potential. This method is formulated for bosons, fermions and distinguishable particles. There are three types ofeffective potentials in accordance with statistics of particles. This is applied to liquid'He at the density 0.03626 mol/cm' and ) transition is reproduced in path-integralMonte Carlo calculation. Calculated energy coincides with thermodynamic data of'He within the error of l .0 K per atom.
