Evgeny A. Ivanov, Maxim A. Konyushikhin, Andrei V. Smilga

摘要:

本文给出了N=4超对称量子力学系统在外部非阿贝尔自对偶规范场中运动的拉格朗日公式。对于任何这样的系统,可以通过引入具有拓扑Chern-Simons型相互作用的额外玻色子变量来写出分量超对称拉格朗日量。对于一类特殊的这样的系统,当场以`t Hooft形式表示时,可以使用调和超空间形式给出超场描述。作为一个新的显式例子,构造了N=4的杨维力学.

英文摘要:

We present a Lagrangian formulation for N=4 supersymmetric quantum-mechanical systems describing the motion in external non-Abelian self-dual gauge fields. For any such system, one can write a component supersymmetric Lagrangian by introducing extra bosonic variables with topological Chern-Simons type interaction. For a special class of such system when the fields are expressed in the `t Hooft ansatz form, it is possible to give a superfield description using harmonic superspace formalism. As a new explicit example, the N=4 mechanics with Yang monopole is constructed.
