Zero-point energy of N perfectly conducting concentric cylindrical shells

摘要

The zero-point (Casimir) energy of N perfectly conducting, infinitely long, concentric cylindrical shells is Calculated utilizing the mode summation technique. The obtained convergent expression is studied as a function of size, curvature and number of shells. Limiting cases, such as infinitely close shells or infinite radius shells are also investigated.
