Spin Gaps in a Frustrated Heisenberg model for CaV4O9
Abstract
I report results of a density matrix renormalization group (DMRG) study of a model for the two dimensional spin-gapped system CaV4O9. 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 24× 11, allowing extrapolation to the thermodynamic limit. I present a substantial improvement to the DMRG algorithms which makes these calculations feasible.
