Proof of completeness of the local conserved quantities in the one-dimensional Hubbard model (2309.09354v3)
Published 17 Sep 2023 in cond-mat.stat-mech, math-ph, math.MP, and nlin.SI
Abstract: We rigorously prove that the local conserved quantities in the one-dimensional Hubbard model are uniquely determined for each locality up to the freedom to add lower-order ones. From this, we can conclude that the local conserved quantities are exhausted by those obtained from the expansion of the transfer matrix.
