The Casimir energy of the twisted string loop: Uniform and two segment loops

Bayin, SS

We calculate the Casimir energy of a two segment loop of string with one normal boundary point and one twisted boundary point. The energy is renormalized relative to the twisted uniform loop. The use of the twisted loop in simplifying untwisted loop calculations is discussed. (C) 1996 American Institute of Physics.
