Nonperturbative features in the Lie-algebraic Kähler sigma model with fermions

Chao-Hsiang Sheu

We investigate the trans-series structure of a quantum mechanical system originating from a Lie-algebraic Kähler sigma model with multiple right-handed chiral fermions, extending p…

Lie-algebraic Kähler sigma models with the U(1) isotropy

Chao-Hsiang Sheu, Mikhail Shifman

We discuss various questions which emerge in connection with the Lie-algebraic deformation of $CP^{1}$ sigma model in two dimensions. First we supersymmetrize the original m…
