Quantum corrections to extremal black brane solutions

Susanne Barisch-Dick, Gabriel Lopes Cardoso, Michael Haack, Alvaro Veliz-Osorio

摘要:

本文讨论了四维N= 2U(1)规范超引力中极端黑膜解的量子修正。我们考虑修改由于某一类高阶导数项以及微扰修正的prepotential。我们使用熵函数形式主义来评估这些修正对奇异膜解决方案的影响,我们给出了几个例子。然后,我们使用一阶流方程来构建解决方案,量子校正相关的潜在的固定点之间的插值。

英文摘要:

We discuss quantum corrections to extremal black brane solutions in N=2 U(1) gauged supergravity in four dimensions. We consider modifications due to a certain class of higher-derivative terms as well as perturbative corrections to the prepotential. We use the entropy function formalism to assess the impact of these corrections on singular brane solutions and we give a few examples. We then use first-order flow equations to construct solutions that interpolate between quantum corrected fixed points of the associated potentials.
