Hi,
I am using the ALPS DMRG code to look at a 1D system. I am comparing the results for small system sizes with the results from exact diagonalisation to verify them. The values match to 5 - 6 decimal places in most cases. However I always get a truncation error or 1. Is this normal behavior? I am using ALPS 1.3.1.
Many Thanks,
Niall.
