The idea of considering the quantum vacuum fluctuations
was suggested  to solve the cosmological constant problem at present.
A vacuum fluctuation
was an even more remote possibility than the chances of a man-made elementary particle destroying the Earth, said Dr Allanach.
In fact, it is ironic that--apparently unbeknownst to Smith--several of the original proponents of these models have, as we shall see, already abandoned the vacuum fluctuation
approach to cosmogeny as implausible and are seeking elsewhere for explanations of the universe's origin.
Physically, a strong vacuum fluctuation
on the horizon briefly violates the generic locality constraint of local quantum field theory in that small region.
Theoretical work  has shown that vacuum fluctuations
near a black hole's horizon are exotic due to curvature distortion of space-time.
In this experiment, the squeezed vacuum field is the bottleneck that leads to a redistribution of vacuum fluctuations
, which can either slow down - if they are behind the bottleneck - or speed up - if they are ahead.
I do not want to amble in relativistic fields of creation and annihilation operators, and vacuum fluctuations
, spontaneous emmission and Lamb shifts.
"The reason why the atom "dies," that is it returns to its original ground state, is that it sees the very small variations in the electromagnetic field which must exist due to quantum theory, known as vacuum fluctuations
," says GE[micro]ran Johansson, Professor of Theoretical and Applied Quantum Physics and leader of the theory group.
Abstract: We investigate the effect of entanglement between two causally separated open charts in de Sitter space on the spectrum of vacuum fluctuations
. We consider a free massive scalar field, and construct the reduced density matrix by tracing out the vacuum state for one of the open charts, as recently derived by Maldacena and Pimentel.
It's confirmed: Matter is merely vacuum fluctuations
In these "vacuum fluctuations
," virtual particles pop in and out of existence.
"This is the first device in which you get a mechanical action as a result of vacuum fluctuations
," says Federico Capasso of Lucent Technologies' Bell Labs in Murray Hill.
