Casimir effect for Elko fields
(2017-07-20)
The Casimir effect for mass dimension one fermion fields (sometimes called Elko) in (3 + 1) dimensions is obtained using Dirichlet boundary conditions. It is shown that the existence of a repulsive force is four times ...
On casimir forces for media whit arbitrary dielectric properties
(Revista Mexicana de Física, 2009)
Vacuum fluctuations and generalized boundary conditions
(American Physical Society, 2013-05)
We present a study of the static and dynamical Casimir effects for a quantum field theory satisfying generalized Robin boundary conditions, of a kind that arises naturally within the context of quantum circuits. Since those ...
Casimir force for absorbing media in an open quantum system framework: Scalar model
(American Physical Society, 2011-11)
In this article we compute the Casimir force between two finite-width mirrors at finite temperature, working in a simplified model in 1+1 dimensions. The mirrors, considered as dissipative media, are modeled by a continuous ...
Entanglement entropy production in the Dynamical Casimir Effect.
(Universidade Federal de Minas GeraisUFMG, 2019-03-01)
In this work, we investigate the production of entanglement entropy in the dynamical Casimir effect at parametric resonance. Symplectic techniques for the description of the time evolution of Gaussian states in bosonic ...
Teoria de Casimir para a energia escura revisitada
(Universidade Federal de Minas GeraisUFMG, 2009-08-07)
We assume that Dark Energy" (of a fixed small region of space at the present cosmic time) may be identified with the system consisting of the vacuum and of a few one-particle states of zero momentum of a scalar quantum ...
Casimir energy density in closed hyperbolic universes
(World Scientific Publ Co Pte Ltd, 2002-11-20)
The original Casimir effect results from the difference in the vacuum energies of the electromagnetic field, between that in a region of space with boundary conditions and that in the same region without boundary conditions. ...

Thermofield dynamics and Casimir effect for fermions
(Elsevier, 2005-05)
A generalization of the Bogoliubov transformation is developed to describe a space compactified fermionic field. The method is the fermionic counterpart of the formalism introduced earlier for bosons [Phys. Rev. A 66 (2002) ...
