Density-matrix spectra for integrable models
I. Peschel, M. Kaulke, Ö. Legeza
The spectra which occur in numerical density-matrix renormalization group (DMRG) calculations for quantum chains can be obtained analytically for integrable models via corner trans…

A DMRG study of the q-symmetric Heisenberg chain
M. Kaulke, I. Peschel
The spin one-half Heisenberg chain with symmetry is studied via density-matrix renormalization. Ground-state energy and -symmetric correlation functions are calcula…
