Query: Multi-magnon quantum many-body scars from tensor operators   We construct a family of three-body spin-1/2 Hamiltonians with a
super-extensive set of infinitely long-lived multi-magnon states. A magnon in
each such state carries either quasi-momentum zero or fixed $p_0\neq$ 0, and
energy $\Omega$ . These multi-magnon states provide an archetypal example of
quantum many-body scars: they are eigenstates at finite energy density that
violate the eigenstate thermalization hypothesis, and lead to persistent
oscillations in local observables in certain quench experiments. On the
technical side, we demonstrate the systematic derivation of scarred
Hamiltonians that satisfy a restricted spectrum generating algebra using an
operator basis built out of irreducible tensor operators. This operator basis
can be constructed for any spin, spatial dimension or continuous non-Abelian
symmetry that generates the scarred subspace.
