Physical Vacuum in Superconductors
Although experiments carried out by Jain et al. showed that the Cooper pairs
obey the strong equivalence principle, The measurement of the Cooper pairs
inertial mass by Tate et al. revealed an anomalous excess of mass. In the
present paper we interpret these experimental results in the framework of an
electromagnetic model of dark energy for the superconductors' vacuum. We argue
that this physical vacuum is associated with a preferred frame. Ultimately from
the conservation of energy for Cooper pairs we derive a model for a variable
vacuum speed of light in the superconductors physical vacuum in relation with a
possible breaking of the weak equivalence principle for Cooper pairs.Comment: 22 pages, 2 figure
Approximation to the Second Order Approximation of Einstein Field Equations with a Cosmological Constant in a Flat Background
Einstein field equations with a cosmological constant are approximated to the
second order in the perturbation to a flat background metric. The final result
is a set of Einstein-Maxwell-Proca equations for gravity in the weak field
regime. This approximation procedure implements the breaking of gauge symmetry
in general relativity. A brief discussion of the physical consequences (Pioneer
anomalous deceleration) is proposed in the framework of the gauge theory of
gravity.Comment: 11 page
Gravitomagnetic London Moment in Rotating Supersolid
Non classical rotational inertia observed in rotating supersolid can
be accounted for by a gravitomagnetic London moment similar to the one recently
reported in rotating superconductive rings.Comment: 2 pages, 1 figure, submitted to Physica
Electromagnetic Dark Energy and Gravitoelectrodynamics of Superconductors
It is shown that Beck and Mackey electromagnetic model of dark energy in
superconductors can account for the non-classical inertial properties of
superconductors, which have been conjectured by the author to explain the
Cooper pair's mass excess reported by Cabrera and Tate. A new Einstein-Planck
regime for gravitation in condensed matter is proposed as a natural scale to
host the gravitoelectrodynamic properties of superconductors.Comment: 9 page
Dissipation of Modified Entropic Gravitational Energy Through Gravitational Waves
The phenomenological nature of a new gravitational type interaction between
two different bodies derived from Verlinde's entropic approach to gravitation
in combination with Sorkin's definition of Universe's quantum information
content, is investigated. Assuming that the energy stored in this entropic
gravitational field is dissipated under the form of gravitational waves and
that the Heisenberg principle holds for this system, one calculates a possible
value for an absolute minimum time scale in nature seconds, which is much
smaller than the Planck time
seconds. This appears together with an absolute possible maximum value for
Newtonian gravitational forces generated by matter Newtons, which is much higher than the
gravitational field between two Planck masses separated by the Planck length
Newtons.Comment: 2 page
Are Superfluid Vortices in Pulsars Violating the Weak Equivalence Principle?
In the present paper we argue that timing irregularities in pulsars, like
glitches and timing noise, could be associated with the violation of the weak
equivalence principle for vortices in the superfluid core of rotating neutron
stars.Comment: 15 page
Coincident-Frequency Entangled Photons in a Homogenous Gravitational Field - A Thought Experiment
Assuming that the Principle of energy conservation holds for
coincident-frequency entangled photons propagating in a homogeneous
gravitational field. It is argued that in this physical context, either Quantum
entanglement or the weak equivalence principle are broken by the photons.Comment: principle of equivalence, entangled photons, gravitational redshif
Gravitoelectromagnetism in (Anti) de Sitter Spacetime
The presence of a non-zero cosmological term in Einstein field equations can
be interpreted as the physical possibility for preferred reference frames
without breaking of general covariance. This possibility is used in the process
of linearizing Einstein field equations in a de Sitter background, and in
formulating the resulting equations in the framework of
gravitoelectromagnetism. It is proposed that this set of equations only applies
to the physical vacuum and not to baryonic (normal) matter.Comment: 12 page
Gravitomagnetic London Moment and the Graviton Mass inside a Superconductor
Using Proca electromagnetic and gravitoelectromagnetic equations the magnetic
and gravitomagnetic properties of a rotating superconductor are respectively
derived. Perfect diamagnetism, and the magnetic London moment are deduced from
the photon mass in the superconductor. Similarly, it is shown that the
conjecture proposed by the authors to resolve the cooper pair mass anomaly
reported by Tate, can be explained by a graviton mass in the superconductor
different with respect to its expected cosmological value.Comment: 15 page
Condensation Energy of a Spacetime Condensate
Starting from an analogy between the Planck-Einstein scale and the dual
length scales in Ginzburg-Landau theory of superconductivity, and assuming that
space-time is a condensate of neutral fermionic particles with Planck mass, we
derive the baryonic mass of the universe. In that theoretical framework
baryonic matter appears to be associated with the condensation energy gained by
spacetime in the transition from its normal (symetric) to its (less symetric)
superconducting-like phase. It is shown however that the critical transition
temperature cannot be the Planck temperature. Thus leaving open the enigma of
the microscopic description of spacetime at quantum level.Comment: 4 page
