On calculations within the nonlinear sigma model
The chiral SU(N) nonlinear sigma model represents one of the simplest case of effective field theory. For the last several decades it has played an extremely important role not only for the low energy phenomenology but also...

GENERALIZED KAHLER GEOMETRY AND MANIFEST N=(2,2) SUPERSYMMETRIC NONLINEAR SIGMA-MODELS.
Generalized complex geometry is a new mathematical framework that is useful for describing the target space of N=(2,2) nonlinear sigma-models. The most direct relation is obtained at the N=(1,1) level when the sigma

Hairy AdS black holes with a toroidal horizon in 4D Einstein-nonlinear sigma-model system
An exact hairy asymptotically locally AdS black hole solution with a flat horizon in the Einstein-nonlinear sigma model system in (3+1) dimensions is constructed. The ansatz for the nonlinear SU(2) field is regular...

Tree-level amplitudes in the nonlinear sigma model
We study in detail the general structure and further properties of the tree-level amplitudes in the SL(N) nonlinear sigma model. We construct the flavor-ordered for reconstruction of the the on-shell amplitudes of effective...

Walls of massive Kähler sigma models on SO(2N)/U(N) and Sp(N)/U(N)
We study the Bogomol'nyi-Prasad-Sommerfield wall solutions in massive Kähler nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N) in three-dimensional spacetime. We show that SO(2N)/U(N) and Sp(N)/U(N) models have ...

Higher-order tree-level amplitudes in the nonlinear sigma model
We present a generalisation of the avour-ordering method applied to the chiral nonlinear sigma model with any number of avours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a p...

Poisson-Lie T-plurality with Spectators
Using a suitable extension of Drinfel'd double we derive formulas for the Poisson-Lie T-plurality transformation with spectators, i.e., for sigma-models whose group of generalized isometries does not act transitively on the target m...
