Hi everyone,
I'm reading DMRG tutorials in http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:DMRG-01_DMRG. When treating spin 1 Heisenberg chain with open boundary conditions, 2 spin 1/2 sites were added to both ends of the spin 1 chain. Why? I have completely no idea about this special treatment. Can anyone give further explanations?
