八元诱导的${\cal N}=7$特殊$G(3)$超共形量子力学

The octonionically-induced ${\cal N}=7$ exceptional $G(3)$ superconformal quantum mechanics

Francesco Toppan

摘要:

给出了以特殊的$G(3)$李超代数为动力学对称的${\cal N}=7$超共形量子力学和以$G(3)$为谱生成超代数的变形振子.这种超共形量子力学,唯一定义的相似变换,通过八元诱导的“准非结合”的方法,获得特殊的${\cal N}=8$ $F(4)$模型。为了构造$G(3)$理论,导出了李代数$g_2$的$7$维表示在跨越$Cl(0,7)$ Clifford代数的$8\times 8$矩阵中的协变嵌入. $G(3)$变形振子的Hilbert空间由实空间坐标的平方可积函数的$16$给出。计算了该理论的谱。

英文摘要:

Both the ${\cal N}=7$ superconformal quantum mechanics possessing the exceptional $G(3)$ Lie superalgebra as dynamical symmetry and its associated deformed oscillator with $G(3)$ as spectrum-generating superalgebra are presented. This superconformal quantum mechanics, uniquely defined up to similarity transformations, is obtained via the octonionically-induced "quasi-nonassociative" method employed to derive the exceptional ${\cal N}=8$ $F(4)$ model. To construct the $G(3)$ theories, the covariant embedding of the $7$-dimensional representation of the Lie algebra $g_2$ within the $8\times 8$ matrices spanning the $Cl(0,7)$ Clifford algebra is derived. The Hilbert space of the $G(3)$ deformed oscillator is given by a $16$-ple of square-integrable functions of a real space coordinate. The spectrum of the theory is computed.
