Classification of Electromagnetic and Gravitational Hopfions by Algebraic Type
Amy Thompson, Alexander Wickes, Joe Swearngin +1
We extend the definition of hopfions to include a class of spin- fields and use this to introduce the electromagnetic and gravitational hopfions of different algebraic types. Th…

Constructing a class of topological solitons in magnetohydrodynamics
Amy Thompson, Joe Swearngin, Alexander Wickes +1
We present a class of topological plasma configurations characterized by their toroidal and poloidal winding numbers, and respectively. The special case of and…

Gravitational Hopfions
Joe Swearngin, Amy Thompson, Alexander Wickes +2
The electromagnetic hopfion (EM hopfion) is a topologically nontrivial solution to the vacuum Maxwell equations with the property that any two field lines belonging to either the e…
