The Gaudin model and the super Bethe ansatz for unitarizable modules over the general linear Lie (super)algebra

Bintao Cao, Wan Keng Cheong, Ngau Lam

Let $A_{g}^{z}$ be the Gaudin algebra for the general linear Lie (super)algebra $g$ with respect to a sequence $z \in C^{ℓ}$ of…

Dualities of Gaudin models with irregular singularities for general linear Lie (super)algebras

Wan Keng Cheong, Ngau Lam

We prove an equivalence between the actions of the Gaudin algebras with irregular singularities for $gl_{d}$ and $gl_{p + m ∣ q + n}$ on the Fock space of $d (p + m)$ bo…

Bethe algebras for unitarizable modules over classical Lie (super)algebras and a duality

Wan Keng Cheong, Ngau Lam

Let $g$ denote the classical Lie algebra $gl_{d}$ , $sp_{2 d}$ , or $so_{2 d}$ with a fixed $*$ -structure $σ$ . Let $M_{1}, \dots, M_{ℓ}$ be un…

The Gaudin model for the general linear Lie superalgebra and the completeness of the Bethe ansatz

Wan Keng Cheong, Ngau Lam

Let $B_{m ∣ n} (z)$ be the Gaudin algebra of the general linear Lie superalgebra $gl_{m ∣ n}$ with respect to a sequence $\underline{\bold…

Quadratic and cubic Gaudin Hamiltonians and super Knizhnik-Zamolodchikov equations for general linear Lie superalgebras

Bintao Cao, Wan Keng Cheong, Ngau Lam

We show that under a generic condition, the quadratic Gaudin Hamiltonians associated to $gl (p + m ∣ q + n)$ are diagonalizable on any singular weight space in any tensor produ…

Gaudin Hamiltonians on unitarizable modules over classical Lie (super)algebras

Wan Keng Cheong, Ngau Lam

Let $M$ be a tensor product of unitarizable irreducible highest weight modules over the Lie (super)algebra $G$ , where $G$ is $gl (m ∣ n)$ , $\mathfrak{os…
