Casimir Energies in the Light of Renormalizable Quantum Field Theories
Effective hadron models commonly require the computation of functional determinants. In the static case these are one–loop vacuum polarization energies, known as Casimir energies. In this talk I will present general methods to efficiently compute renormalized one–loop vacuum polarization energies and energy densities and apply these methods to construct soliton solutions within a variational ap...
متن کاملAcoustic Casimir pressure for arbitrary media
In this paper we derive a general expression for the acoustic Casimir pressure between two parallel slabs made of arbitrary materials and whose acoustic reflection coefficients are not equal. The formalism is based on the calculation of the local density of modes using a Green’s function approach. The results for the Casimir acoustic pressure are generalized to a sphere/plate configuration usin...
متن کاملCasimir effect in external magnetic field
We compute the influence of an external magnetic field on the Casimir energy of a massive charged scalar field confined between two parallel infinite plates. For this case the obtained result shows that the magnetic field inhibits the Casimir effect. The Casimir effect can be generally defined as the effect of a non-trivial space topology on the vacuum fluctuations of relativistic quantum field...
متن کاملCasimir Effects in Renormalizable Quantum Field Theories
We review the framework we and our collaborators have developed for the study of one– loop quantum corrections to extended field configurations in renormalizable quantum field theories. We work in the continuum, transforming the standard Casimir sum over modes into a sum over bound states and an integral over scattering states weighted by the density of states. We express the density of states ...
متن کاملCasimir effect in external magnetic field
In this paper we examine the Casimir effect for charged fields in presence of external magnetic field. We consider scalar field (connected with spinless particles) and the Dirac field (connected with 1/2-spin particles). In both cases we describe quantum field using the canonical formalism. We obtain vacuum energy by direct solving field equations and using the mode summation method. In order t...
