AI总结:

本文研究守恒律对双迹形变可穿越虫洞的影响,发现 $U(1)$ 守恒流耦合导致流体力学极限下体规范场能动张量违反 ANEC,使虫洞可穿越,并探讨了其对信息传输和多体量子隐形传态的意义。

摘要:

我们研究守恒律对通过双迹形变实现可穿越虫洞的影响。将极大延拓的 $(d+1)$ 维黑膜几何的两个渐近边界与 $U(1)$ 守恒流算符耦合后,我们发现流体力学极限下相应体规范场的量子物质能动张量违反平均零能量条件(ANEC),使虫洞可穿越。将结果应用于轴子双侧黑洞解,我们讨论了虫洞开口如何依赖电荷扩散常数,这如何影响可通过虫洞发送的信息量,以及涉及守恒流算符的多体量子隐形传态协议的可能含义。

英文摘要:

We study the effects of conservation laws on wormholes that are made traversable by a double trace deformation. After coupling the two asymptotic boundaries of a maximally extended $(d+1)$ dimensional black brane geometry with $U(1)$ conserved current operators, we find that the quantum matter stress-energy tensor of the corresponding bulk gauge fields in the hydrodynamic limit violates the averaged null energy condition (ANEC), rendering the wormhole traversable. Applying our results to axionic two-sided black hole solutions, we discuss how the wormhole opening depends on the charge diffusion constant, how this affects the amount of information that can be sent through the wormhole, and possible implications for many-body quantum teleportation protocols involving conserved current operators.
