Semiclassical Bethe ansatz and AdS/CFT [PDF]

Fortschritte der Physik, 2005
AbstractThe Bethe ansatz can be used to compute anomalous dimensions in 𝒩 = 4 SYM theory. The classical solutions of the sigma‐model on AdS5 × S5 can also be parameterized by an integral equation of Bethe type. The relationship between the two Bethe ansätze is reviewed.

Boundary perimeter Bethe ansatz [PDF]

Journal of Physics A: Mathematical and Theoretical, 2017
Abstract We study the partition function of the six-vertex model in the rational limit on arbitrary Baxter lattices with reflecting boundary. Every such lattice is interpreted as an invariant of the twisted Yangian. This identification allows us to relate the partition function of the vertex model to the Bethe wave function of an open

Bethe Ansatz inside Calogero-Sutherland models

SciPost Physics
We study the trigonometric quantum spin-Calogero–Sutherland model, and the Haldane–Shastry spin chain as a special case, using a Bethe-Ansatz analysis. We harness the model's Yangian symmetry to import the standard tools of integrability for Heisenberg ...

Pseudo-differential equations, and the Bethe ansatz for the classical Lie algebras [PDF]

, 2007
The correspondence between ordinary differential equations and Bethe ansatz equations for integrable lattice models in their continuum limits is generalised to vertex models related to classical simple Lie algebras.

Bethe Ansatz equations for the classical A^(1)_n affine Toda field theories [PDF]

, 2014
We establish a correspondence between classical A(1)n affine Toda field theories and An Bethe Ansatz systems. We show that the connection coefficients relating specific solutions of the associated classical linear problem satisfy functional relations of ...

Nonstandard Bethe Ansatz equations for open O(N) spin chains

Nuclear Physics B, 2018
The double row transfer matrix of the open O(N) spin chain is diagonalized and the Bethe Ansatz equations are also derived by the algebraic Bethe Ansatz method including the so far missing case when the residual symmetry is O(2M+1)×O(2N−2M−1).

Bethe states for the two-site Bose–Hubbard model: A binomial approach

Physics Letters B, 2015
We calculate explicitly the Bethe vectors states by the algebraic Bethe ansatz method with the gl(2)-invariant R-matrix for the two-site Bose–Hubbard model.
