Ben Meiring, Ido Shyovitz, Sebastian Waeber, Amos Yarom

AI总结:

本文研究五维 AdS 空间中带磁荷黑膜在短时电场作用下的响应,发现当存在 't Hooft 反常且温度足够低时会出现长寿命振荡电流,并通过数值模拟验证了该“反常共振”效应。

摘要:

我们讨论了描述 d 维 AdS 空间中带磁荷黑膜的解析解。聚焦于 d=5 的情形,我们研究了黑膜对外部短时电场激励的响应。我们认为,当理论具有 't Hooft 反常时,在足够低的温度下,电场关闭很久之后仍会观察到长寿命的振荡电流。我们通过数值研究展示了这种“反常共振”效应。

英文摘要:

We discuss analytic solutions describing magnetically charged black branes in $d$ dimensional AdS space. Focusing on $d=5$, we study the response of the brane to an external short lived electric field. We argue that when the theory possesses an 't Hooft anomaly then at sufficiently low temperature a long lived oscillatory current will be observed long after the electric field has been turned off. We demonstrate this ``anomalous resonance'' effect via a numerical study.
