Abstract

Inspired by the Kovtun-Son-Starinet bound, we propose that holography impose a lower bound on the Casimir effect. For simplicity, we focus on the Casimir effect between parallel planes for 3d conformal field theories and briefly comment on the generalizations to other boundary shapes and higher dimensions. Remarkably, all the holographic models impose a universal lower bound of the Casimir effect. We verify the holographic bound by free theories, the Ising model, and $O(N)$ models at critical points and prove it for the 2d case.
