电场与量子虫洞

Electric fields and quantum wormholes

Dalit Engelhardt, Ben Freivogel, Nabil Iqbal

摘要:

电场可以穿过经典的爱因斯坦-罗森桥。Maldacena和Susskind最近提出,在动力学引力理论中,普通微扰量子的纠缠应该被看作是在粒子之间建立一个量子版的爱因斯坦-罗森桥,或者一个“量子虫洞”。我们证明了在低能量有效场论,有一个精确的意义上,电场也可以线程这样的量子虫洞。我们定义了一个非微扰的“虫洞敏感性”,它测量了通过任何类型的虫洞的电场的容易程度。量子虫洞的磁化率被U(1)规范耦合的幂抑制,但可以通过足够大量的纠缠物质使其数值相等。

英文摘要:

Electric fields can thread a classical Einstein-Rosen bridge. Maldacena and Susskind have recently suggested that in a theory of dynamical gravity the entanglement of ordinary perturbative quanta should be viewed as creating a quantum version of an Einstein-Rosen bridge between the particles, or a "quantum wormhole". We demonstrate within low-energy effective field theory that there is a precise sense in which electric fields can also thread such quantum wormholes. We define a non-perturbative "wormhole susceptibility" that measures the ease of passing an electric field through any sort of wormhole. The susceptibility of a quantum wormhole is suppressed by powers of the U(1) gauge coupling relative to that for a classical wormhole but can be made numerically equal with a sufficiently large amount of entangled matter.
