真空边界效应

Vacuum Boundary Effects

M. Asorey, J. M. Munoz-Castaneda

摘要:

从量子信息的观点分析了边界条件对量子场论真空结构的影响。特别地,我们分析了边界条件对边界熵和纠缠熵的影响。对无质量自由场论边界效应的分析指出,边界条件是真空结构的一个新的丰富信息源。在所有情况下,熵并不沿着从紫外到红外的流动而增加。

英文摘要:

The effect of boundary conditions on the vacuum structure of quantum field theories is analysed from a quantum information viewpoint. In particular, we analyse the role of boundary conditions on boundary entropy and entanglement entropy. The analysis of boundary effects on massless free field theories points out the relevance of boundary conditions as a new rich source of information about the vacuum structure. In all cases the entropy does not increase along the flow from the ultraviolet to the infrared.
