Abstract: The Fock-space coupled-cluster (FSCC) method appears as a robust computational scheme if reformulated within the eigenvalue independent partitioning framework (EIP-FSCC) which efficiently deals with the intruder states that cause convergence problems in its standard effective…

Abstract: We adopt a geometric perspective on Fock space to provide two complementary insights into the eigenstates in many-body-localized fermionic systems. On the one hand, individual many-bodylocalized eigenstates are well approximated by a Slater determinant of…
