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_Î…

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…
