Vortices with fractional flux in two-gap superconductors and in extended Faddeev model
Egor Babaev
We discuss vortices allowed in two-gap superconductors, bilayer systems and in equivalent extended Faddeev model. We show that in these systems there exist vortices which carry an…

Dual neutral variables and knot solitons in triplet superconductors
Egor Babaev
In this paper we derive a dual presentation of free energy functional for spin-triplet superconductors in terms of gauge-invariant variables. The resulting equivalent model in ferr…

Hidden symmetry and knot solitons in a charged two-condensate Bose system
Egor Babaev, Ludvig D. Faddeev, Antti J. Niemi
We show that a charged two-condensate Ginzburg-Landau model or equivalently a Gross-Pitaevskii functional for two charged Bose condensates, can be mapped onto a version of the nonl…
