Entanglement entropy and complexity of singular subregions in deformed CFT

Understand

In the framework of the AdS/CFT correspondence, imposing a scalar field in the bulk space-time leads to deform the corresponding CFT in the boundary, which may produce corrections to entanglement entropy, as well as the so-called subregion complexity.

• We have computed such corrections for a set of singular subregions including kink, cones and creases in different dimensions.
• Our calculations shows new singular terms including universal logarithmic corrections for entanglement entropy and subregion complexity for some distinct values of conformal weight.
