Non-Abelian Global Strings at Chiral Phase Transition
Muneto Nitta, Noriko Shiiki
We construct non-Abelian global string solutions in the U(N)_L x U(N)_R linear sigma model. These strings are the most fundamental objects which are expected to form during the chi…

Skyrme Strings
Muneto Nitta, Noriko Shiiki
We construct nontopological string solutions with U(1) Noether charge in the Skyrme model with a pion mass term, and examine their stability by taking linear perturbations. The sol…

Collective quantization of axially symmetric gravitating B=2 skyrmion
Hisayuki Sato, Nobuyuki Sawado, Noriko Shiiki
In this paper we perform collective quantization of an axially symmetric skyrmion with baryon number two.The rotational and isorotational modes are quantized to obtain the static p…
