Revisiting the Casimir energy with general boundary conditions and applications in 1D crystals Muñoz Castañeda, José María Bordag, Michael Santamaría Sanz, Lucía Quantum field theory under the influence of classical backgrounds Casimir effect Boundary conditions Física Matemáticas Physics Mathematics We obtain new expressions for the Casimir energy between plates that are mimicked by the most general possible boundary conditions allowed by the principles of quantum field theory. This result enables to provide the quantum vacuum energy for scalar fields propagating under the influence of a one-dimensional crystal represented by a periodic potential formed by an infinite array of identical potentials with compact support.
