AI中文摘要:
我们在1+3维闵可夫斯基时空中,自由无质量实标量场真空态下,两个不相交球形区域之间包含大部分纠缠的模式的形状被找到。利用Klco-Beck-Savage方法,我们近似了这两个球体之间真空最纠缠模式(MEMs)的场和动量分布。我们定义了一个非微扰的模式交换纠缠提取协议,其中两个类空分离的探针提取两个区域之间的最大纠缠量。我们的结果是朝着理解量子场局部纠缠结构迈出的第一步,精确定位了在QFT中编码可访问量子关联的确切自由度。
英文摘要:
We find the shape of the modes containing most of the entanglement between two disjoint spherical regions in the vacuum of a free massless real scalar field in 1+3 Minkowski spacetime. Using the Klco-Beck-Savage method we approximate the field and momentum profile of the vacuum most entangled modes (MEMs) between two spheres. We define a non-perturbative mode-swap entanglement harvesting protocol where two spacelike separated probes extract the maximal amount of entanglement between two regions. Our results are a first step in the direction of understanding the local entanglement structure of quantum fields, pinpointing the exact degrees of freedom that encode accessible quantum correlations in QFT.
