The study uncovers symmetry-protected topological phases with coexisting spontaneous symmetry breaking in the triangular Majorana-Hubbard ladder model of interacting Majorana fermions.
Conjectures an asymptotic formula for the Haldane gap at large integer spins and reports that topological order in the spin-1 chain vanishes smoothly in ladders without a phase transition.
