Absence of nontrivial local conserved quantities in the quantum compass model on the square lattice
arXiv:2502.10791 · doi:10.1063/5.0268742
Abstract
By extending the method developed by Shiraishi, we prove that the quantum compass model on the square lattice does not possess any local conserved quantities except for the Hamiltonian itself.
