非反对易孤子

Non-anticommutative solitons

Sergei V. Ketov, Olaf Lechtenfeld

摘要:

某些2+1维超对称西格玛模型具有多孤子解,有散射和无散射。我们通过用Clifford代数替换奇超空间坐标的Grassmann代数来使这些系统进行非反交换变形。静态CP^1和散射U(2)孤子被构造,并且由于变形而具有额外的自旋1/2自由度。阿贝尔BPS解也存在,但具有无限作用,与Moyal情况相反。

英文摘要:

Certain supersymmetric sigma models in 2+1 dimensions feature multi-soliton solutions, with and without scattering. We subject these systems to a non-anticommutative deformation by replacing the Grassmann algebra of the odd superspace coordinates with a Clifford algebra. Static CP^1 and scattering U(2) solitons are constructed and carry an additional spin-1/2 degree of freedom due to the deformation. Abelian BPS solutions exist as well but have infinite action, in contrast to the Moyal case.
