Monodromy bootstrap for SU (2| 2) quantum spectral curves: from Hubbard model to AdS3/CFT2

S Ekhammar, D Volin - Journal of High Energy Physics, 2022 - Springer
A bstract We propose a procedure to derive quantum spectral curves of AdS/CFT type by
requiring that a specially designed analytic continuation around the branch point results in …

A note on odd reflections of super Yangian and Bethe ansatz

K Lu - Letters in Mathematical Physics, 2022 - Springer
In a recent paper (Molev A, in Lett Math Phys 112 (8): 15, 2022), Molev introduced
analogues of the odd reflections for the super Yangian Y (gl m| n) and obtained a transition …

[HTML][HTML] Folding QQ-relations and transfer matrix eigenvalues: towards a unified approach to Bethe ansatz for super spin chains

Z Tsuboi - Nuclear Physics B, 2024 - Elsevier
Extending the method proposed in [1], we derive QQ-relations (functional relations among
Baxter Q-functions) and T-functions (eigenvalues of transfer matrices) for fusion vertex …

[HTML][HTML] Completeness of Bethe ansatz for Gaudin models associated with gl (1| 1)

K Lu - Nuclear Physics B, 2022 - Elsevier
We study the Gaudin models associated with gl (1| 1). We give an explicit description of the
algebra of Hamiltonians (Gaudin Hamiltonians) acting on tensor products of polynomial …

Superopers revisited

AM Zeitlin - arxiv preprint arxiv:2307.02675, 2023 - arxiv.org
The relation between special connections on the projective line, called Miura opers, and the
spectra of integrable models of Gaudin type provides an important example of the geometric …

On Bethe eigenvectors and higher transfer matrices for supersymmetric spin chains

K Lu - Journal of High Energy Physics, 2023 - Springer
A bstract We study the\({\mathfrak {gl}} _ {m\mid n}\) XXX spin chains defined on tensor
products of highest weight\({\mathfrak {gl}} _ {m\mid n}\)-modules. We show that the on-shell …

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

WK Cheong, N Lam - Journal of Algebra, 2024 - Elsevier
Let M be a tensor product of unitarizable irreducible highest weight modules over the Lie
(super) algebra G, where G is gl (m| n), osp (2 m| 2 n) or spo (2 m| 2 n). We show, using …

Completeness of Bethe Ansatz for Gaudin Models with 𝔤𝔩 (1| 1) Symmetry and Diagonal Twists

K Lu - Symmetry, 2022 - mdpi.com
We studied the Gaudin models with gl (1| 1) symmetry that are twisted by a diagonal matrix
and defined on tensor products of polynomial evaluation gl (1| 1)[t]-modules. Namely, we …
