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…
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…
Infinite Family of Integrable Sigma Models Using Auxiliary Fields
Christian Ferko, Liam Smith
We introduce a class of sigma models which are parameterized by a function of one variable. In addition to the physical field , these models include an auxiliary field $v_α…
