# The local conserved quantities of the closed XXZ chain

@article{Nienhuis2021TheLC, title={The local conserved quantities of the closed XXZ chain}, author={Bernard Nienhuis and Onno E. Huijgen}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2021}, volume={54} }

Integrability of the XXZ model induces an extensive number of conserved quantities. In this paper we give a closed form expression for the series of local conserved charges of the XXZ model on a closed chain with or without a twist. We prove that each element of the series commutes with the Hamiltonian.

### Integrable spin chain with Hilbert space fragmentation and solvable real-time dynamics.

- Physics, MathematicsPhysical review. E
- 2021

It is argued that this spin-1/2 chain is one of the simplest quantum integrable models, yet it has quite remarkable physical properties, and a nonlocal map is constructed that connects the model with the Maassarani-Mathieu spin chain, also known as the SU(3) XX model.
