摘要
In this talk, I will explore the eigenvalue problem of integrable spin chains using the Bethe ansatz. I will begin with a review of the rational Q-system, a powerful tool for solving Bethe equations. Then, I will demonstrate how Bethe solutions evolve under twist boundaries. Most importantly, I will highlight our key findings: the discovery of hidden symmetries and magnetic strings under specific open boundary parameters. These novel phenomena provide new insights into the interplay between symmetries and boundary conditions.
