Cosmological Uses of Casimir Energy
A precise zeta-function calculation shows that the contribution of the vacuum energy to the observed value of the cosmological constant can possibly have the desired order of magnitude albeit the sign strongly depends on the topology of the universe. The non-renormalizable, infinite contributions which have been recently shown to occur when one physically imposes boundary conditions on quantum ...
متن کاملCasimir energy of dielectric systems
This paper is devoted to study of Casimir effect [ 1] in dielectrics at zero temperature in the framework of quantum field theory. The presentation of the subject is based on the results and proofs derived by the author. The paper is organized as follows. In section 2 a new formula for the Casimir energy of a dispersive dilute dielectric ball [ 2] is discussed. In section 3 a path-integral meth...
متن کاملDivergences in the Casimir energy
The divergence found by Nesterenko, Lambiase and Scarpetta is attributed to the existence of edges in the considered manifold.
متن کاملLocal Casimir energy for solitons
A direct calculation of the one-loop contributions to the energy density of bosonic and supersymmetric φ4 kinks exhibits: (1) Local mode regularization. Regularization of the Casimir energy density maintains equality for the soliton and trivial vacua of not only the total number of field oscillation modes, but also the total mode density at each point in space. This yields the anomalous part of...
