Dynamical local and non-local Casimir atomic phases
François Impens, Claudio Ccapa Ttira, Ryan O. Behunin +1
We develop an open-system dynamical theory of the Casimir interaction between coherent atomic waves and a material surface. The system --- the external atomic waves --- disturbs th…
Non-additive dynamical Casimir atomic phases
François Impens, Claudio Ccapa Ttira, Paulo A. Maia Neto
We discuss a fundamental property of open quantum systems: the quantum phases associated with their dynamical evolution are non-additive. We develop our argument by considering a m…
Non-local double-path Casimir phase in atom interferometers
François Impens, Ryan O. Behunin, Claudio Ccapa Ttira +1
We present a quantum open system theory of atom interferometers evolving in the quantized electromagnetic field bounded by an ideal conductor. Our treatment reveals an unprecedente…
Lifshitz formula for the Casimir force and the Gelfand-Yaglom theorem
C. Ccapa Ttira, C. D. Fosco, F. D. Mazzitelli
We provide a Quantum Field Theory derivation of Lifshitz formula for the Casimir force due to a fluctuating real scalar field in dimensions. The field is coupled to two imper…
Vacuum polarization from confined fermions in 3 + 1 dimensions
C. Ccapa Ttira, C. D. Fosco, E. Losada
We study the main properties of the one-loop vacuum polarization function for massless spinor QED4 in a slab, namely, with fields defined on M in R^(3+1), such that M = {(x0, ...,…
Quantum effects in with an extra compactified dimension
C. Ccapa Ttira, C. D. Fosco, A. P. C. Malbouisson +1
We evaluate one-loop effects for in the presence of an extra compactified dimension, in a non-trivial vacuum for the gauge field, such that a non-vanishing magnetic flu…
