Exact models for trimerization and tetramerization in spin chains
Stephan Rachel, Martin Greiter
We present exact models for an antiferromagnetic S=1 spin chain describing trimerization as well as for an antiferromagnetic S=3/2 spin chain describing tetramerization. These mode…

DMRG studies of critical SU(N) spin chains
M. Fuehringer, S. Rachel, R. Thomale +2
The DMRG method is applied to integrable models of antiferromagnetic spin chains for fundamental and higher representations of SU(2), SU(3), and SU(4). From the low energy spectrum…
