报告摘要:
This talk discusses the Casimir effect of a wedge and its holographic dual. We prove that the wedge Casimir effect is universally determined by the displacement operator in smooth limit. Besides, we argue that the wedge Casimir energy increases with the opening angle. Furthermore, we construct the holographic dual of wedges in AdS/BCFT in general dimensions. We verify that our proposal can produce the correct smooth limit. Next, we discuss the wedge contribution to holographic entanglement entropy and find it increases with the opening angle, similar to the wedge Casimir energy. Finally, we conclude with some open questions.
