非相对论CFTs对偶的陪集构造

Coset Construction for Duals of Non-relativistic CFTs

Sakura Schafer-Nameki, Masahito Yamazaki, Kentaroh Yoshida

摘要:

我们系统地分析了背景,全息投影到非相对论性的CFTs,通过构建它们作为陪集的薛定谔群及其变体。这些陪集G/H是一般的非约化,我们讨论的一般性如何度量这样的空间可以确定从一个非退化的H-不变的对称两个形式。将此应用于d=2的薛定谔代数,我们再现了五维背景提出的费米在么正性的,并在合理的物理假设下,我们证明了这种背景的唯一性。所提出的引力对偶的利弗希茨不动点,伽利略对称性是缺席的,也适合于这种组织方案和独特的这种背景也可以显示。

英文摘要:

We systematically analyze backgrounds that are holographic duals to non-relativistic CFTs, by constructing them as cosets of the Schrodinger group and variants thereof. These cosets G/H are generically non-reductive and we discuss in generality how a metric on such spaces can be determined from a non-degenerate H-invariant symmetric two-form. Applying this to the d=2 Schrodinger algebra, we reproduce the five-dimensional backgrounds proposed as duals of fermions at unitarity, and under reasonable physical assumptions, we demonstrate uniqueness of this background. The proposed gravity dual of the Lifshitz fixed-point, for which Galileian symmetry is absent, also fits into this organizational scheme and uniqueness of this background can also be shown.
