D=5超引力和黑弦中的G2对偶

G2 Dualities in D=5 Supergravity and Black Strings

Geoffrey Compère, Sophie de Buyl, Ella Jamsin, Amitabh Virmani

摘要:

五维极小超引力在两个交换Killing方向上降维,得到一个G2陪集模型。陪集模型的对称群可以通过对种子解应用群变换来生成新解。我们表明,在一个一般的解决方案,属于嘉当和幂零子代数的G2的发电机作为缩放和规范变换,分别。G2的其余生成元形成sl(2,R)+sl(2,R)子代数,其可用于生成非平凡电荷。我们使用这些生成器来推广五维克尔弦在许多方面。特别地,我们构造了具有五维最小超引力的自旋电磁黑弦。我们分析了这些黑弦的物理性质,并研究了它们的热力学。我们还探讨了它们与黑环的关系。

英文摘要:

Five dimensional minimal supergravity dimensionally reduced on two commuting Killing directions gives rise to a G2 coset model. The symmetry group of the coset model can be used to generate new solutions by applying group transformations on a seed solution. We show that on a general solution the generators belonging to the Cartan and nilpotent subalgebras of G2 act as scaling and gauge transformations, respectively. The remaining generators of G2 form a sl(2,R)+sl(2,R) subalgebra that can be used to generate non-trivial charges. We use these generators to generalize the five dimensional Kerr string in a number of ways. In particular, we construct the spinning electric and spinning magnetic black strings of five dimensional minimal supergravity. We analyze physical properties of these black strings and study their thermodynamics. We also explore their relation to black rings.
