我们构建了一个近 $AdS_2$ 的解决方案，描述了一个永恒的可穿越虫洞。该解包含在两个边界之间的外部耦合影响下量子场产生的负零能。同时，我们讨论通过相关交互耦合的两个 SYK 系统。这两种情况的物理原理非常相似。它们都共享一个相同的“引力”子区域。该子部门内的解决方案为几乎保角不变的动力学奠定了基础。我们在重力和 SYK 模型中详细研究了该系统。耦合的 SYK 模型在有限温度下有一个有趣的相图，显示了低温下的热 AdS 相和高温下的黑洞相之间常见的霍金-佩奇转变。有趣的是，这两个阶段在微规范系综中是连续连接的。
We construct a nearly-$AdS_2$ solution describing an eternal traversable wormhole. The solution contains negative null energy generated by quantum fields under the influence of an external coupling between the two boundaries. In parallel, we discuss two SYK systems coupled by a relevant interaction. The physics of the two cases is very similar. They both share a "gravitational" subsector which is identical. The solution within this subsector sets the stage for dynamics which is almost conformal invariant. We study this system in detail, both in gravity and in the SYK model. The coupled SYK models have an interesting phase diagram at finite temperature, displaying the usual Hawking-Page transition between the thermal AdS phase at low temperature and the black hole phase at high temperature. Interestingly, these two phases are continuously connected in the microcannonical ensemble.
