Using infinite projected entangled-pair states and exact diagonalizations, we show that in both cases the ground state is a simplex solid state with a twofold degeneracy, in which the N spins belonging to a simplex (i.e., a complete graph) form a singlet. Theses states can be seen as generalizations of valence bond solid states known to be stabilized in certain SU(2) spin models.Dimensional Quantum AntiferromagnetsLarge-N LimitGround-StatesValence-BondSpin-Peierlstext::journal::journal article::research article
