Bethe Ansatz for Quantum-Deformed Strings

  title={Bethe Ansatz for Quantum-Deformed Strings},
  author={Fiona K. Seibold and Alessandro Sfondrini},
Two distinct η-deformations of strings on AdS5×S can be defined; both amount to integrable quantum deformations of the string non-linear sigma model, but only one is itself a superstring background. In this paper we compare their conjectured all-loop worldsheet S matrices and derive the corresponding Bethe equations. We find that, while the S matrices are apparently different, they lead to the same Bethe equations. Moreover, in either case the eigenvalues of the transfer matrix, which encode… Expand


On quantum deformations of AdS3 × S3 × T4 and mirror duality
Abstract We consider various integrable two-parameter deformations of the AdS3 × S3 × T4 superstring with quantum group symmetry. Working on the string worldsheet in light-cone gauge and toExpand
Puzzles of η-deformed AdS5 × S5
A bstractWe derive the part of the Lagrangian for the sigma model on the η-deformed AdS5 × S5 space which is quadratic in fermions and has the full dependence on bosons. We then show that thereExpand
Long-range psu(2,2|4) Bethe Ansatze for gauge theory and strings
We generalize various existing higher-loop Bethe ansatze for simple sec- tors of the integrable long-range dynamic spin chain describing planar N = 4 Super Yang-Mills Theory to the full psu(2,2|4)Expand
The exact spectrum and mirror duality of the (AdS5 × S5)η superstring
We discuss the spectrum of a string propagating on η-deformed AdS5 × S5 by treating its worldsheet theory as an integrable quantum field theory. The exact S-matrix of this field theory is given by aExpand
The Bethe-ansatz for N = 4 super Yang-Mills
We derive the one loop mixing matrix for anomalous dimensions in N=4 Super Yang-Mills. We show that this matrix can be identified with the Hamiltonian of an integrable SO(6) spin chain with vectorExpand
Quantum Deformations of the One-Dimensional Hubbard Model
The centrally extended superalgebra psu(2|2) �R 3 was shown to play an important role for the integrable structures of the one-dimensional Hubbard model and of the planar AdS/CFT correspondence. HereExpand
The off-shell symmetry algebra of the light-cone AdS5x S5 superstring
We analyze the psu(2,2|4) supersymmetry algebra of a superstring prop- agating in the AdS5 × S 5 background in the uniform light-cone gauge. We consider the off-shell theory by relaxing theExpand
Scale invariance of the η-deformed AdS5 × S5 superstring, T-duality and modified type II equations
Abstract We consider the ABF background underlying the η -deformed AdS 5 × S 5 sigma model. This background fails to satisfy the standard IIB supergravity equations which indicates that theExpand
The Bethe ansatz approach for factorizable centrally extended S-matrices
We consider the Bethe ansatz solution of integrable models interacting through factorized S-matrices based on the central extension of the su(2|2) symmetry. The respective su(2|2) R-matrix isExpand
Towards integrability for AdS3/CFT2
In this thesis we consider certain supersymmetric string theories on curved backgrounds containing the three-dimensional anti-de Sitter space, AdS3. On the one hand, these are gravity theories inExpand
