Multimagnon quantum many-body scars from tensor operators

We construct a family of three-body spin-1/2 Hamiltonians with a superextensive set of infinitely long-lived multimagnon states. A magnon in each such state carries either quasimomentum zero or fixed p_{0}≠0, and energy Ω. These multimagnon states provide an archetypal example of quantum many-body s...
