calculation of local density of states
Dear all, Is it possible to calculate local density of states within the framework of exact diagonalization in ALPS? Thanks a lot!

If you do fulldiag of the model, you of course get full eigenenergy spectrum. -- Ryo IGARASHI, Ph.D. rigarash@hosi.phys.s.u-tokyo.ac.jp OpenPGP fingerprint: BAD9 71E3 28F3 8952 5640 6A53 EC79 A280 6A19 2319

The full spectrum alone does not give you the local density of states though - you'll need to do more. The answer thus is that the ALPS code does not do it at the moment, but it could be added. Matthias
