This review is dedicated to two-dimensional sigma models with flag manifold target spaces,
which are generalizations of the familiar CP n− 1 and Grassmannian models. They naturally …

A bstract In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma
models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag …

Abstract Recently, SU (3) chains in the symmetric and self-conjugate representations have
been studied using field theory techniques. For certain representations, namely rank-p …

A bstract We examine topological terms of (2+ 1) d sigma models and their consequences in
the light of classifications of invertible quantum field theories utilizing bordism groups. In …

The nature of the insulating phases of the SU (N)-generalization of the one-dimensional
Kondo lattice model is investigated by means of nonperturbative approaches. By extending …

A general strategy is proposed to explore the low-energy properties of two-dimensional
nonlinear $\sigma $ models with $\theta $ terms. We demonstrate its application to nonlinear …
