利用纠缠熵探测AdS虫洞

Probing AdS Wormholes by Entanglement Entropy

Mitsutoshi Fujita, Yasuyuki Hatsuda, Tadashi Takayanagi

摘要:

本文研究arXiv:0808.2481 [hep-th]中构造的洛伦兹AdS虫洞解.它们都是在IIB型超引力中AdS空间和平坦空间之间插值的经典解。我们计算全息纠缠熵来探索这种几何。我们的分析表明,在它的全息双规范理论中存在一个质量隙,并且两个边界之间的纠缠比我们天真地期望的虫洞要受到抑制。我们还研究了在这个时空中探测D膜的全息电导率。

英文摘要:

In this paper, we study the Lorentzian AdS wormhole solutions constructed in arXiv:0808.2481 [hep-th]. Each of them is a classical solution interpolating between an AdS space and a flat space in type IIB supergravity. We calculate the holographic entanglement entropy to probe this geometry. Our analysis shows that there exits a mass gap in its holographic dual gauge theory and that the entanglement between the two boundaries is rather suppressed than that we naively expect for wormholes. We also examine the holographic conductivity on a probe D-brane in this spacetime.
