Abstract

While conducting analysis related to a DARPA-funded project to evaluate possible
structure of the energy density present in a Casimir cavity as predicted by the
dynamic vacuum model, a micro/nano-scale structure has been discovered that
predicts negative energy density distribution that closely matches requirements
for the Alcubierre metric. The simplest notional geometry being analyzed as part
of the DARPA-funded work consists of a standard parallel plate Casimir cavity
equipped with pillars arrayed along the cavity mid-plane with the purpose of
detecting a transient electric field arising from vacuum polarization
conjectured to occur along the midplane of the cavity. An analytic technique
called worldline numerics was adapted to numerically assess vacuum response to
the custom Casimir cavity, and these numerical analysis results were observed to
be qualitatively quite similar to a two-dimensional representation of energy
density requirements for the Alcubierre warp metric. Subsequently, a toy model
consisting of a 1 m diameter sphere centrally located in a 4 m diameter cylinder
was analyzed to show a three-dimensional Casimir energy density that correlates
well with the Alcubierre warp metric requirements. This qualitative correlation
would suggest that chip-scale experiments might be explored to attempt to
measure tiny signatures illustrative of the presence of the conjectured
phenomenon: a real, albeit humble, warp bubble.
