Progress in Establishing a Connection Between the Electromagnetic Zero-Point Field and Inertia
We report on the progress of a NASA-funded study being carried out at the
Lockheed Martin Advanced Technology Center in Palo Alto and the California
State University in Long Beach to investigate the proposed link between the
zero-point field of the quantum vacuum and inertia. It is well known that an
accelerating observer will experience a bath of radiation resulting from the
quantum vacuum which mimics that of a heat bath, the so-called Davies-Unruh
effect. We have further analyzed this problem of an accelerated object moving
through the vacuum and have shown that the zero-point field will yield a
non-zero Poynting vector to an accelerating observer. Scattering of this
radiation by the quarks and electrons constituting matter would result in an
acceleration-dependent reaction force that would appear to be the origin of
inertia of matter (Rueda and Haisch 1998a, 1998b). In the subrelativistic case
this inertia reaction force is exactly newtonian and in the relativistic case
it exactly reproduces the well known relativistic extension of Newton's Law.
This analysis demonstrates then that both the ordinary, F=ma, and the
relativistic forms of Newton's equation of motion may be derived from Maxwell's
equations as applied to the electromagnetic zero-point field. We expect to be
able to extend this analysis in the future to more general versions of the
quantum vacuum than just the electromagnetic one discussed herein.Comment: 6 pages, no figure
Toward an Interstellar Mission: Zeroing in on the Zero-Point-Field Inertia Resonance
While still an admittedly remote possibility, the concept of an interstellar
mission has become a legitimate topic for scientific discussion as evidenced by
several recent NASA activities and programs. One approach is to extrapolate
present-day technologies by orders of magnitude; the other is to find new
regimes in physics and to search for possible new laws of physics. Recent work
on the zero-point field (ZPF), or electromagnetic quantum vacuum, is promising
in regard to the latter, especially concerning the possibility that the inertia
of matter may, at least in part, be attributed to interaction between the
quarks and electrons in matter and the ZPF. A NASA-funded study (independent of
the BPP program) of this concept has been underway since 1996 at the Lockheed
Martin Advanced Technology Center in Palo Alto and the California State
University at Long Beach. We report on a new development resulting from this
effort: that for the specific case of the electron, a resonance for the
inertia-generating process at the Compton frequency would simultaneously
explain both the inertial mass of the electron and the de Broglie wavelength of
a moving electron as first measured by Davisson and Germer in 1927. This line
of investigation is leading to very suggestive connections between
electrodynamics, inertia, gravitation and the wave nature of matter.Comment: Space Technology and Applications International Forum (STAIF-2000)

Update on an Electromagnetic Basis for Inertia, Gravitation, the Principle of Equivalence, Spin and Particle Mass Ratios
A possible connection between the electromagnetic quantum vacuum and inertia
was first published by Haisch, Rueda and Puthoff (1994). If correct, this would
imply that mass may be an electromagnetic phenomenon and thus in principle
subject to modification, with possible technological implications for
propulsion. A multiyear NASA-funded study at the Lockheed Martin Advanced
Technology Center further developed this concept, resulting in an independent
theoretical validation of the fundamental approach (Rueda and Haisch, 1998ab).
Distortion of the quantum vacuum in accelerated reference frames results in a
force that appears to account for inertia. We have now shown that the same
effect occurs in a region of curved spacetime, thus elucidating the origin of
the principle of equivalence (Rueda, Haisch and Tung, 2001). A further
connection with general relativity has been drawn by Nickisch and Mollere
(2002): zero-point fluctuations give rise to spacetime micro-curvature effects
yielding a complementary perspective on the origin of inertia. Numerical
simulations of this effect demonstrate the manner in which a massless
fundamental particle, e.g. an electron, acquires inertial properties; this also
shows the apparent origin of particle spin along lines originally proposed by
Schroedinger. Finally, we suggest that the heavier leptons (muon and tau) may
be explainable as spatial-harmonic resonances of the (fundamental) electron.
They would carry the same overall charge, but with the charge now having
spatially lobed structure, each lobe of which would respond to higher frequency
components of the electromagnetic quantum vacuum, thereby increasing the
inertia and thus manifesting a heavier mass.Comment: 10 pages, 4 figures, AIP Conf. Proc., Space Technology and

The Zero-Point Field and the NASA Challenge to Create the Space Drive
This NASA Breakthrough Propulsion Physics Workshop seeks to explore concepts that could someday enable interstellar travel. The effective superluminal motion proposed by Alcubierre (1994) to be a possibility owing to theoretically allowed space-time metric distortions within general relativity has since been shown by Pfenning and Ford (1997) to be physically unattainable. A number of other hypothetical possibilities have been summarized by Millis (1997). We present herein an overview of a concept that has implications for radically new propulsion possibilities and has a basis in theoretical physics: the hypothesis that the inertia and gravitation of matter originate in electromagnetic interactions between the zero-point field (ZPF) and the quarks and electrons constituting atoms. A new derivation of the connection between the ZPF and inertia has been carried through that is properly co-variant, yielding the relativistic equation of motion from Maxwell's equations. This opens new possibilities, but also rules out the basis of one hypothetical propulsion mechanism: Bondi's "negative inertial mass," appears to be an impossibility
Inertial Mass Viewed as Reaction of the Vacuum to Accelerated Motion
Preliminary analysis of the momentum flux (or of the Poynting vector) of the classical electromagnetic version of the quantum vacuum consisting of zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to acceleration attributed to inertia may be a force of opposition originating in the vacuum. This analysis avoids the ad hoc modeling of particle-field interaction dynamics used previously by Haisck Rueda and Puthoff (1994) to derive a similar result. This present approach is not dependent upon what happens at the particle point but on how an external observer assesses the kinematical characteristics of the zero-point radiation impinging on the accelerated object. A relativistic form of the equation of motion results from the present analysis
Topological Dual Systems for Spaces of Vector Measure p-Integrable Functions
[EN] We show a Dvoretzky-Rogers type theorem for the adapted version of the q-summing operators to the topology of the convergence of the vector valued integrals on Banach function spaces. In the pursuit of this objective we prove that the mere summability of the identity map does not guarantee that the space has to be finite dimensional, contrary to the classical case. Some local compactness assumptions on the unit balls are required. Our results open the door to new convergence theorems and tools regarding summability of series of integrable functions and approximation in function spaces, since we may find infinite dimensional spaces in which convergence of the integrals, our vector valued version of convergence in the weak topology, is equivalent to the convergence with respect to the norm. Examples and applications are also given.This work was supported by the Ministerio de Economia y Competitividad (Spain) under Grants MTM2015-66823-C2-2-P (P. Rueda) and MTM2012-36740-C02-02 (E. A.

The support localization property of the strongly embedded subspaces of banach function spaces
El archivo no es la versión final publicada del trabajo.[EN] Motivated by the well known Kadec-Pelczynski disjointifcation theorem, we undertake
an analysis of the supports of non-zero functions in strongly embedded subspaces of
Banach functions spaces. The main aim is to isolate those properties that bring additional
information on strongly embedded subspaces. This is the case of the support localization
property, which is a necessary condition fulflled by all strongly embedded subspaces. Several
examples that involve Rademacher functions, the Volterra operator, Lorentz spaces
or Orlicz spaces are provided.P. Rueda acknowledges with thanks the support of the Ministerio de Econom´ıa y Competitividad (Spain) MTM2011-22417. E. A.
