All Local Conserved Quantities of the One-Dimensional Hubbard Model (2301.03621v5)
Published 9 Jan 2023 in cond-mat.stat-mech, math-ph, math.MP, and nlin.SI
Abstract: We present the exact expression for all local conserved quantities of the one-dimensional Hubbard model. We identify the operator basis constructing the local charges and find that nontrivial coefficients appear in the higher-order charges. We derive the recursion equation for these coefficients, and some of them are explicitly given. There are no other local charges independent of those we obtained.
