偶数维自由标量场球面单值性的Renyi熵

Renyi entropy for spherical monodromy of free scalar fields in even dimensions

J. S. Dowker

摘要:

研究了余维2球面单值缺陷对共形标量自由场论的影响。共形异常计算(以两种方式),从而雷尼和纠缠熵。计算结果表明,在一定的单值通量范围内,$C_T$中心荷为负,并对任意偶数维球进行了计算。A提出了与现有结果可能存在的冲突。

英文摘要:

The effect of a co--dimension--2 spherical monodromy defect on the free--field theory of a conformal scalar is investigated. The conformal anomaly is computed (in two ways) and thence the Rényi and entanglement entropies. The $C_T$ central charge is found to be negative for a range of monodromy flux.The calculations are pursued for any even dimensional sphere. A Possible conflict with existing results is raised.
