Importance truncation for the in-medium similarity renormalization group

NUCLEAR STRUCTURE ⁴He, ^40,48,52,60Ca, ^56,68,78Ni; calculated ground state energy. Importance truncation (IT) methods in the nonperturbative in-medium similarity renormalization group (IMSRG) approach. Investigated the effect of truncation in different sub-blocks of the two-body Hamiltonian on the solution error.
