We provide a new construction of the dressing cosets sigma-models which is based on an isotropic gauging of the E-models. As an application of this new approach, we show that the recently constructed multi-parametric integrable deformations of the principal chiral model are the dressing cosets, they are therefore automatically renormalizable and their dynamics can be completely characterized in terms of current algebras.

  1. Twists of trigonometric sigma models

    hep-th 2025-04 accept novelty 7.0 of 10

    A new class of Z_N-twisted integrable sigma models is constructed from 4d Chern-Simons theory, and Z2 twisting by an outer automorphism of SU(n) produces models inequivalent to the untwisted ones.

  2. Integrable deformations of dimensionally reduced gravity

    hep-th 2025-02 conditional novelty 6.0 of 10

    Auxiliary field and Yang-Baxter deformations of D=2 dimensionally reduced gravity are shown to admit flat Lax representations, with the auxiliary field case preserving the Hamiltonian integrability structure.

    hep-th 2019-09 conditional novelty 6.0 of 10

    For a warped AdS background with a GKP string vacuum, the author argues that the particle-side integrability constraint on the warp factor derivative g''(0) equals the worldsheet S-matrix factorization constraint on t...
