四维引力场Anomaly的全息纠缠熵

Holographic Entanglement Entropy for Gravitational Anomaly in Four Dimensions

Tibra Ali, S. Shajidul Haque, Jeff Murugan

摘要:

计算了3+1维反常多项式$\mathrm{Tr} R^2$的全息纠缠熵。利用计算量子场论纠缠熵的微扰方法,我们还计算了来自背景引力Chern-Simons项的宇称奇对对偶场论的纠缠熵的贡献.我们发现,在领导秩序的背景几何的扰动,这两个贡献匹配,除了对数发散项的场论侧。我们将这种额外的贡献解释为编码我们对产生几何扰动的源的无知。

英文摘要:

We compute the holographic entanglement entropy for the anomaly polynomial $\mathrm{Tr} R^2$ in 3+1 dimensions. Using the perturbative method developed for computing entanglement entropy for quantum field theories, we also compute the parity odd contribution to the entanglement entropy of the dual field theory that comes from a background gravitational Chern-Simons term. We find that, in leading order in the perturbation of the background geometry, the two contributions match except for a logarithmic divergent term on the field theory side. We interpret this extra contribution as encoding our ignorance of the source which creates the perturbation of the geometry.
