Auxiliary Field Deformations of (Semi-)Symmetric Space Sigma Models
Daniele Bielli, Christian Ferko, Liam Smith +1
We generalize the auxiliary field deformations of the principal chiral model (PCM) introduced in arXiv:2405.05899 and arXiv:2407.16338 to sigma models whose target manifolds are sy…
Integrable Higher-Spin Deformations of Sigma Models from Auxiliary Fields
Daniele Bielli, Christian Ferko, Liam Smith +1
We construct a new infinite family of integrable deformations of the principal chiral model (PCM) parameterized by an interaction function of several variables, which extends the f…
T-Duality and -like Deformations of Sigma Models
Daniele Bielli, Christian Ferko, Liam Smith +1
We initiate the study of the interplay between T-duality and classical stress tensor deformations in two-dimensional sigma models. We first show that a general Abelian T-duality co…
Boundary Bethe ansatz in massless AdS3
Daniele Bielli, Vasileios Moustakis, Alessandro Torrielli
We construct the boundary algebraic Bethe Ansatz for the AdS3 X S3 X T4 integrable reflection problem restricted to the massless sector. We derive the double-row monodromy and find…
Auxiliary Field Sigma Models and Yang-Baxter Deformations
Daniele Bielli, Christian Ferko, Liam Smith +1
We combine the Yang-Baxter (YB) and bi-Yang-Baxter (bi-YB) deformations with higher-spin auxiliary field deformations to construct multi-parameter families of integrable deformatio…
JT gravity from non-Abelian T-duality
Daniele Bielli, Silvia Penati, Anayeli Ramirez
We study the geometries obtained by performing super non-Abelian T-duality of the Principal Chiral Model on OSp. While the initial model represents an appropriate 3D supergr…
Boundary scattering in massless
Daniele Bielli, Vaibhav Gautam, Vasileios Moustakis +2
We study the boundary integrability problem of the massless sector of string theory. Exploiting the difference-form of the massless scattering theory…
