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 …

We study CP 2 skyrmion crystals in the ferromagnetic SU (3) Heisenberg model with a
generalization of the Dzyaloshinskii-Moriya interaction and the Zeeman term. The model …

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 …

A bstract We study fractional Skyrmions in a ℂP 2 baby Skyrme model with a generalization
of the easy-plane potential. By numerical methods, we find stable, metastable, and unstable …

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 …

A bstract The spectral flow is ubiquitous in the physics of soliton-fermion interacting systems.
We study the spectral flows related to a continuous deformation of background soliton …

We consider quantum mechanical systems of spin chain type, with finite-dimensional Hilbert
spaces and $\mathcal {N}= 2$ or $\mathcal {N}= 4$ supersymmetry, described in $\mathcal …
