Abstract
I report results of a density matrix renormalization group (DMRG) study of a model for the two dimensional spin-gapped system CaVO. This study represents the first time that DMRG has been used to study a two dimensional system on large lattices, in this case as large as , allowing extrapolation to the thermodynamic limit. I present a substantial improvement to the DMRG algorithms which makes these calculations feasible.
