Critical theory of the topological quantum phase transition in a spin-2 chain
Hong-Chen Jiang, Stephan Rachel, Zheng-Yu Weng +2
We systematically study the phase diagram of S=2 spin chain, by means of density-matrix renormalization group and exact diagonalization methods and confirm the presence of a dimer…

Topological Insulators and Mott Physics from the Hubbard Interaction
Stephan Rachel, Karyn Le Hur
We investigate the Hubbard model on the honeycomb lattice with intrinsic spin orbit interactions as a paradigm for two-dimensional topological band insulators in the presence of in…
