Many-body density matrices on a two-dimensional square lattice : noninteracting and strongly interacting spinless fermions
The reduced density matrix of an interacting system can be used as the basis for a truncation scheme, or in an unbiased method to discover the strongest kind of correlation in the ground state. In this paper, we investigate the structure of the many-body fermion density matrix of a small cluster in...
