Non Abelian Vortices as Instantons on Noncommutative Discrete Space
Hitoshi Ikemori, Shinsaku Kitakado, Hideharu Otsu +1
There seems to be close relationship between the moduli space of vortices and the moduli space of instantons, which is not yet clearly understood from a standpoint of the field the…
Solitons of Sigma Model on Noncommutative Space as Solitons of Electron System
H. Otsu, T. Sato, H. Ikemori +1
We study the relationship of soliton solutions for electron system with those of the sigma model on the noncommutative space, working directly in the operator formalism. We find th…
Lost equivalence of nonlinear sigma and models on noncommutative space
H. Otsu, T. Sato, H. Ikemori +1
We show that the equivalence of nonlinear sigma and models which is valid on the commutative space is broken on the noncommutative space. This conclusion is arrived at thr…
New BPS Solitons in 2+1 Dimensional Noncommutative CP^1 Model
H. Otsu, T. Sato, H. Ikemori +1
Investigating the solitons in the non-commutative model, we have found a new set of BPS solitons which does not have counterparts in the commutative model.
