More on Classical Stability of Hopf-like Solitons of the Toroidal-Twisted type
Chao-Hsiang Sheu, Mikhail Shifman
The Faddeev-Hopf model [1] supporting Hopfions was shown to emerge in the low-energy limit of four-dimensional scalar quantum electrodynamics (QED) with two charged scalar fields […
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 sigma model in two dimensions. First we supersymmetrize the original m…
Defects on Domain Lines
Evgeniy Kurianovych, Mikhail Shifman
Based on recent experimental results, we give field-theoretic description of defects localized on the domain lines on thin films. We describe topology of our model and solve…
Spectral Flow in Instanton Computations and the \boldmath{$\b$} functions
Alexander Monin, Mikhail Shifman, Arkady Vainshtein
We discuss various differences in the instanton-based calculations of the functions in theories such as Yang-Mills and on one hand, and theory wit…
Peculiarities of beta functions in sigma models
Oleksandr Gamayun, Andrei Losev, Mikhail Shifman
In this paper we consider perturbation theory in generic two-dimensional sigma models in the so-called first-order formalism, using the coordinate regularization approach. Our goal…
Remarks on Baby Skyrmion Lie-Algebraic Generalization
Chao-Hsiang Sheu, Mikhail Shifman
We discuss generalized baby Skyrmions emerging in a (1+2)-dimensional model with a certain Lie-algebraic structure. The same result applies to the Polyakov-Belavin instantons i…
