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…
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…
Decomposition of meron configuration of SU(2) gauge field
M. Hirayama, J. Yamashita
For the meron configuration of the SU(2) gauge field in the four dimensional Minkowskii spacetime, the decomposition into an isovector field $\bn$, isoscalar fields and , an…
Elliptic solutions of the Skyrme model
M. Hirayama, C. -G. Shi, J. Yamashita
A class of exact solutions of the Skyrme model are obtained. They are described by the Weierstrass -function or the Jacobi elliptic function. They are not solitonic but of wav…
Class of exact solutions of the Skyrme and the Faddeev model
M. Hirayama, J. Yamashita
Class of exact solutions of the Skyrme and the Faddeev model are presented. In contrast to previously found solutions, they are produced by the interplay of the two terms in the La…
