动力学紧维的热力学相变

Thermodynamic phase transitions from dynamical compact dimensions

Zachary Polonsky, Alex Flournoy

摘要:

我们进行了一个双商的全球广告$_4$,并研究其热性质。我们发现,一个双商产生一个时空与一个膨胀的紧凑的尺寸。研究对偶CFT的纠缠,我们发现,在早期,时空具有热性质,在临界时间后消失。对于缓慢膨胀,该临界时间取决于预期的膨胀速率,但随着更快的膨胀速率变得更加敏感。

英文摘要:

We perform a double quotient of global AdS$_4$ and study its thermal properties. We find that a double quotient yields a spacetime with an expanding compact dimension. Studying the entanglement of the dual CFT we find that, at early times, the spacetime has thermal properties which disappear after a critical time. For slow expansion, this critical time depends on the expansion rate as expected, but becomes much more sensitive with more rapid expansion rates.
