Isoscalar E0, E1, and E2 strength in Ca-40
(American Physical Society, 2001)
The giant resonance region from 10 particles at small angles including 0 degrees. Strength corresponding to 97 +/- 11%, 108 +/- 12%, and 62 + 10-20 % of the isoscalar E0, E2, and E1 sum rules, respectively, was identified ...
Fourth-order diffusion Monte Carlo algorithms for solving quantum many-body problems
(American Physical Society, 2001)
By decomposing the important sampled imaginary time Schrodinger evolution operator to fourth order with positive coefficients, we derived a number of distinct fourth-order diffusion Monte Carlo algorithms. These sophisticated ...
