For features see here.
Input files listed here are out-of-date for the latest version of the code. Also, CPU times noted below have improved substantially since I first wrote this in 2010. Therefore, CPU times here no longer reflect what the code (v2.2+) produces.
This is a 16 site chain. Click on a figure to see full size.
Compare to PhysRevB.48.10345. Fig. 6(a) (input file), and fig. 6(c) (input file) are shown below. Fig 6(b) is not shown because DMRG++ cannot presently do uneven chains; reflection symmetry required for the full lattice. Fig. 7 is not shown due to the Spin=1 Heisenberg not being implemented (see issues).
