Symmetry-protected topological phases in the SU(N) Heisenberg spin chain: a Majorana-fermion approach
Pierre Fromholz, Philippe Lecheminant
The nature of symmetry-protected topological phases of Heisenberg spin chains in totally symmetric representations of rank N of the SU(N) group is investigated through a Majorana f…
Symmetry-protected topological phases in two-leg SU(N) spin ladder with unequal spins
Sylvain Capponi, Pierre Fromholz, Philippe Lecheminant +1
Chiral Haldane phases are examples of one-dimensional topological states of matter which are protected by projective SU() group (or its subgroup $\mathbb{Z}_N \times \mathbb{Z}_…
Entanglement topological invariants for one-dimensional topological superconductors
Pierre Fromholz, Giuseppe Magnifico, Vittorio Vitale +2
Entanglement is known to serve as an order parameter for true topological order in two-dimensional systems. We show how entanglement of disconnected partitions defines topological…
