GAUGED HETEROTIC SIGMA-MODELS [PDF]
Modern Physics Letters A, 1994 The gauging of isometries in general sigma-models which include fermionic terms which represent the interaction of strings with background Yang-Mills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and then the (1, 0) supersymmetric generalization of the gauge action given.

Integrable crosscaps in classical sigma models
Journal of High Energy Physics, 2023 We study the integrable boundaries and crosscaps of classical sigma models. We show that there exists a classical analog of the integrability condition and KT-relation of the boundary and crosscap states of quantum spin chains.

The equivariant A-twist and gauged linear sigma models on the two-sphere [PDF]
, 2015 A bstractWe study two-dimensional N=2,2$$ \mathcal{N}=\left(2,\;2\right) $$ supersymmetric gauged linear sigma models (GLSM) on the Ω-deformed sphere, SΩ2, which is a one-parameter deformation of the A-twisted sphere.

Supersymmetric Sigma Model Geometry [PDF]
Symmetry, 2012 This is a review of how sigma models formulated in Superspace have become important tools for understanding geometry. Topics included are: The (hyper)kähler reduction; projective superspace; the generalized Legendre construction; generalized Kähler geometry and constructions of hyperkähler metrics on Hermitian symmetric spaces.

Resurgence and dynamics of O(N) and Grassmannian sigma models [PDF]
, 2015 A bstractWe study the non-perturbative dynamics of the two dimensional O(N ) and Grassmannian sigma models by using compactification with twisted boundary conditions on ℝ×S1$$ \mathbb{R}\times {S}^1 $$, semi-classical techniques and resurgence. While the

DUALITY IN FUZZY SIGMA MODELS [PDF]
International Journal of Modern Physics A, 2004 Nonlinear "sigma" models in two dimensions have BPS solitons which are solutions of self- and anti-self-duality constraints. In this paper, we find their analogues for fuzzy sigma models on fuzzy spheres which were treated in detail by us in earlier work.

Topological sigma models on supermanifolds
Nuclear Physics B, 2017 This paper concerns constructing topological sigma models governing maps from semirigid super Riemann surfaces to general target supermanifolds. We define both the A model and B model in this general setup by defining suitable BRST operators and physical

Double soft theorems and shift symmetry in nonlinear sigma models [PDF]
, 2015 We show both the leading and subleading double soft theorems of the nonlinear sigma model follow from a shift symmetry enforcing Adler's zero condition in the presence of an unbroken global symmetry. They do not depend on the underlying coset G/H and are

S-matrices and quantum group symmetry of k-deformed sigma models [PDF]
, 2015 Recently, two kinds of integrable deformations of the string world sheet theory in the gauge/gravity correspondence have been constructed (Delduc et al 2014 Phys. Rev. Lett. 112 051601; Hollowood et al 2014 J. Phys. A: Math. Theor. 47 495402).
