molecules    [PDF]

The density matrix renormalization group (DMRG) method, an efficient solver
of lattice models in 1d, has been adapted to solve real-space problems. We use
DMRG to study the behavior of soft-Coulomb interacting matter, reporting
accurate benchmarks for small systems. We compare with Hartree-Fock and the
local density approximation, noting similarities and differences with 3d. We
study how correlation grows as bonds stretch.
