Integrability from a single conservation law in quantum spin chains
Akihiro Hokkyo
We prove that, for translationally invariant quantum spin chains with finite-range interactions, the existence of a specific conservation law implies the presence of infinitely man…

Rigorous Test for Quantum Integrability and Nonintegrability
Akihiro Hokkyo
The integrability of a quantum many-body system, which is characterized by the presence or absence of local conserved quantities, drastically impacts the dynamics of isolated syste…
