The Bethe Ansatz as a Quantum Circuit [PDF]

open access: yesQuantum, 2023
The Bethe ansatz represents an analytical method enabling the exact solution of numerous models in condensed matter physics and statistical mechanics. When a global symmetry is present, the trial wavefunctions of the Bethe ansatz consist of plane wave ...

Preparing Bethe Ansatz Eigenstates on a Quantum Computer

open access: yesPRX Quantum, 2021
Several quantum many-body models in one dimension possess exact solutions via the Bethe ansatz method, which has been highly successful for understanding their behavior.

Asymmetric Bethe Ansatz

open access: yesSciPost Physics Core
The recently proposed exact quantum solution for two $\delta$-function-interacting particles with a mass-ratio $3\!:\!1$ in a hard-wall box [Y. Liu, F. Qi, Y. Zhang and S. Chen, iScience 22, 181 (2019)] violates the conventional necessary condition for a

The large-N limit of 4d superconformal indices for general BPS charges

open access: yesJournal of High Energy Physics, 2022
We study the superconformal index of N $$ \mathcal{N} $$ = 1 quiver theories at large-N for general values of electric charges and angular momenta, using both the Bethe Ansatz formulation and the more recent elliptic extension method. We are particularly

Supersymmetric Vacua and Bethe Ansatz [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2009
An announcement of some results of a longer paper where the supersymmetric vacua of two dimensional N=2 susy gauge theories with matter are shown to be in one-to-one correspondence with the eigenstates of integrable spin chain Hamiltonians. The Heisenberg spin chain is mapped to the two dimensional U(N) theory with fundamental hypermultiplets, the XXZ ...

Twisted rational r-matrices and algebraic Bethe ansatz: Application to generalized Gaudin and Richardson models

open access: yesNuclear Physics B, 2021
In the present paper we develop the algebraic Bethe ansatz approach to the case of non-skew-symmetric gl(2)⊗gl(2)-valued Cartan-non-invariant classical r-matrices with spectral parameters. We consider the two families of these r-matrices, namely, the two

LARGE-N AND BETHE ANSATZ [PDF]

open access: yesModern Physics Letters A, 2004
We describe an integrable model, related to the Gaudin magnet, and its relation to the matrix model of Brézin, Itzykson, Parisi and Zuber. Relation is based on Bethe ansatz for the integrable model and its interpretation using orthogonal polynomials and saddle point approximation.
