3 Casimir effect We will derive the Casinir effect in three dimen- sions, making use of the Euler-Maclaurin formula where θη _ 1 for n > 0,4,-1/2, and θη 0 for n <0. (You don't need to prove this formula.) Let us consider walls of length L. Let EL be the vacuum energy inside the box. We now insert a conducting plate at a distance RL parallel to one of the walls, dividing the volume into two. Denote ER and...
