Dual neutral variables and knot solitons in triplet superconductors
2002 (English)In: Physical Review Letters, ISSN 0031-9007, Vol. 88, no 17Article in journal (Refereed) Published
Abstract [en]

We derive a dual presentation of a free energy functional for spin-triplet superconductors in terms of gauge-invariant variables. The resulting equivalent model in ferromagnetic phase has a form of a version of the Faddeev model. This allows one, in particular, to conclude that spin-triplet superconductors allow formation of stable finite-length closed vortices (knotted solitons).
