Quantum many-body scars: A quasiparticle perspective
Weakly interacting quasiparticles play a central role in the low-energy description of many
phases of quantum matter. At higher energies, however, quasiparticles cease to be well …

Exactly solvable subspaces of nonintegrable spin chains with boundaries and quasiparticle interactions
C Matsui - Physical Review B, 2024 - APS
We propose two strategies to construct a family of nonintegrable spin chains with exactly
solvable subspaces based on the idea of quasiparticle excitations from the matrix product …
