AdS上的$p$-型表面电荷:重整化和守恒

$p$-Form Surface Charges on AdS: Renormalization and Conservation

Erfan Esmaeili, Vahid Hosseinzadeh

摘要:

计算了AdS $_{d+1}$时空边界上$p$形式理论的表面电荷.边界上的反项产生发散的角项,这些角项全息地重新正规化辛形式。不同的边界条件的选择导致不同的表达式的电荷和相关的通量。在通常的标准AdS边界条件下,存在守恒的零模电荷。此外,我们探讨了两个漏边界条件,允许无穷多个电荷形成一个阿贝尔代数和非零通量。最后,我们讨论了磁$p$-形式的电荷和电/磁对偶性。

英文摘要:

Surface charges of a $p$-form theory on the boundary of an AdS$_{d+1}$ spacetime are computed. Counter-terms on the boundary produce divergent corner-terms which holographically renormalize the symplectic form. Different choices of boundary conditions lead to various expressions for the charges and the associated fluxes. With the usual standard AdS boundary conditions, there are conserved zero-mode charges. Moreover, we explore two leaky boundary conditions which admit an infinite number of charges forming an Abelian algebra and non-vanishing flux. Finally, we discuss magnetic $p$-form charges and electric/magnetic duality.
