Cross-fertilization of Ferreira's Hopfions And Electromagnetic Knots
Chang-Guang Shi, Minoru Hirayama
The interrelation between Ferreira's Hopf solitons of a conformal nonlinear model and the electromagnetic knots found by Raada et al. is investigated. It is sho…
Approximate vortex solution of Faddeev model
Chang-Guang Shi, Minoru Hirayama
Through an Ansatz specifying the azimuthal-angle dependence of the solution, the static field equation for vortex of the Faddeev model is converted to an algebraic ordinary differe…
Reduction of static field equation of Faddeev model
Minoru Hirayama, Chang-Guang Shi
A method to solve the static field equation of the Faddeev model is presented. For an special combination of the concerned field, we adopt a form which is compatible with the field…
Restricting profile function of hedgehog Skyrmion
Jun Yamashita, Minoru Hirayama
The profile function for the hedgehog Skyrmion is investigated. After discussing how the form of the profile function is restricted by the field equation, the s tatic energy is num…
Domain wall solution of the Skyrme model
Chang-Guang Shi, Minoru Hirayama
A class of domain-wall-like solutions of the Skyrme model is obtained analytically. They are described by the tangent hyperbolic function, which is a special limit of the Weierstra…
Estimation of the Lin-Yang bound of the least static energy of the Faddeev model
Minoru Hirayama, Hitoshi Yamakoshi, Jun Yamashita
Lin and Yang's upper bound E_Q <= cQ^(3/4) of the least static energy E_Q of the Faddeev model in a sector with a fixed Hopf index Q is investigated. By constructing an explicit tr…
