- Title
Vacuum energy of a nonrelativistic string with nontrivial boundary condition.
- Authors
Jahan, A.; Sukhasena, S.
- Abstract
We derive the partition function of a nonrelativistic quantum string whose ends are allowed to freely move along the two-angled straight solid rods. We first derive the classical solution of the model and then use it to derive the partition function utilizing the path integral method. We show that the vacuum energy is the sum of the Lüscher potential plus a term which depends on the relative angle between the rods.
