Modified Algebraic Bethe Ansatz S. Belliard Institut Denis Poisson |

|
Abstract: I will discuss a way to calculate spectrum and states for models without U(1) symmetries such as the open XXZ spin chain. The modified algebraic Bethe ansatz will be described in that case, and off-shell action of the related transfer matrix will be established. It will allows to calculate Slavnov’s formula for scalar product of the associated states. Language: English |
