Proposed experiment on the continuity of quantum entanglement
We propose experiments on quantum entanglement for investigating the Einstein
Podolsky Rosen (EPR) problem with the polarization directions of photons. These
experiments are performed to investigate whether the defined polarization
directions in an entangled state are teleported between entangled photons.
EPR-type sequential experiments are performed using a twin-photon beam and two
pairs of linear polarization analyzers under the cross-Nicol condition (i.e.,
orthogonal to each other). If the third filter whose polarization angle is 45
degrees is set between the first cross-Nicol filters, the beam intensity is
changed from 0 to 12.5 %, and at the second cross-Nicol filters, the beam
intensity is changed from 0 to 25 %. In this experiment, we predict that the
"continuity of quantum entanglement" under a pure Hamiltonian evolution is
detected.Comment: 6 pages, 5 figure
Single photon Michelson-Morley experiment via de Broglie-Bohm picture: An interpretation based on the hypothesis of frame dragging
The Michelson-Morley experiment is considered via a single photon
interferometer and a hypothesis of the dragging of the permittivity of free
space and permeability of free space. The Michelson-Morley experimental results
can be interpreted using de Broglie-Bohm picture. In the global positioning
system (GPS) experiment, isotropic constancy of the speed of light, c, was
confirmed by direct one way measurement. That is, Michelson-Morley experiments
without interference are confirmed every day; therefore the hypothesis of frame
dragging is a suitable explanation of the Michelson-Morley experimental
results.Comment: 9 pages, 6 figure
Proposed experiment to test the non-locality hypothesis in transient light-interference phenomena
The transient phenomena of the Mach-Zender interferometer are discussed. To
test the non-locality hypothesis, a single mode laser with a large coherence
length is used. The behavior of a photon and its wave packets in the paths of
the interferometer are discussed. Coherent photons have wave packets that
overlap, thus their interference pattern is influenced by the overlap of the
wave packets of other photons in transient phenomena. The proposed transient
light-interference experiment will provide experimental data testing the
non-locality hypothesis.Comment: 10 pages, 7 figure
Compatibility of the theory of special relativity with an absolute reference frame with a longitudinal Doppler shift
We show the compatibility of the theory of special relativity with the
absolute reference frame with a longitudinal Doppler shift. Using two absolute
velocities vA and vS, the relative velocity u is derived. Thereafter the
Doppler frequency is derived using the relative velocity u. We also show the
method for detecting the absolute reference frame. The representation of the
theory of special relativity using the absolute reference frame appears more
intuitive than an orthodox interpretation.Comment: 11 pages, 8 figure
Experimental evidence of the ether-dragging hypothesis in GPS data
In the global positioning system (GPS) satellites, the earth-centered,
earth-fixed (ECEF) reference frame is used for calculations. In the application
of the theory of special relativity to GPS satellites, one must use the ECEF
reference frame; another reference frame, for example one based on the solar
system, cannot be applied to GPS satellite experiments. Therefore, the ECEF
reference frame is a stationary gravitational frame.Comment: 18 pages, 9 figure
Proposal of Signaling by Interference Control of Delayed-Choice Experimental Setup
We propose a new signaling system using the experimental setup of Wheeler's
delayed-choice experiment previously carried out. In the delayed-choice
experiment, the experimental setup shows a wave property or a particle property
at the time when the experimental conditions of the wave-particle duality of
photons are chosen. Choice signals can be used as transmitting signals and the
wave-particle duality of photons is used as receiving signals. For example, if
we choose the wave property of a photon as a transmitting signal, we detect the
interference of the wave at the detector that can be used as a receiving
signal. Therefore, the experimental setup of the delayed-choice experiment can
transmit information through interference.Comment: 7 pages, 5 figure
Incompatibility between the principle of the constancy of the speed of light and the Lorentz contraction in the GPS Experiment
Incompatibility between the principle of the constancy of the speed of light
and the Lorentz contraction in the global positioning system (GPS) is
discussed. The GPS works precisely in the earth-centered locally inertial (ECI)
coordinate system on the condition that the speed of light c is assumed to be
constant regardless of the inertial motion of the GPS satellites and the earth.
The inertial system of the earth travels not only in the solar system at the
velocity 30 km/s but also in the cosmic microwave background (CMB) at the
velocity 700 km/s. The deviation on the car navigation system by the Lorentz
contraction of 700 km/s is maximally estimated as 54 m. However, such a large
deviation is not observed: that is, the Lorentz contraction is not observed in
the gravitational field of the earth. If there is a Lorentz contraction, the
GPS cannot work so precisely. The GPS satellites are in the gravitational field
of the earth, therefore the system should be interpreted by the theory of
general relativity as well as special relativity.Comment: 8 pages, 3 figure
Interpretation of the slight periodic displacement in the Michelson-Morley experiments
The slight periodic displacements in the Michelson-Morley interference
experiments do not show ether-drift; however, they do show the effects of the
theory of general relativity that is, the effects of acceleration and
deceleration to the interference condition of the Michelson-Morley interference
experiments. Therefore, these slight periodic variations are very significant
and important for strengthening the theory of special and general relativity.
The slight periodic displacements are discussed from the viewpoint of the
theories of general relativity and interference.Comment: 5 pages, 4 figure
Proposed experiment of which-way detection by longitudinal momentum transfer in Young's double slit experiment
The momentum of a photon may reveal the answer to the "which way" problem of
Young's double slit experiments. A photon passing through the boundary between
two media, in which a photon travels at different velocities, undergoes a
momentum change according to the law of conservation of momentum. The momentum
of the photon is transferred locally to the medium, and the boundary between
the media receives stress, which determines the photon trajectory. An
experiment is performed using a crystal plate that can transform the stress to
electric charge. We are able to detect the electric charge after the detection
of the photon on the screen, and control the sensitivity of photon detection.
By means of this proposed experiment it is determined whether or not an attempt
to detect the "which way" of photon travel destroys the interference patterns.Comment: 5 pages, 3 figure
Nonlinear stochastic biasing of halos: Analysis of cosmological N-body simulations and perturbation theories
It is crucial to understand and model a behavior of galaxy biasing for future
ambitious galaxy redshift surveys. Using 40 large cosmological N-body
simulations for a standard LambdaCDM cosmology, we study the cross-correlation
coefficient between matter and the halo density field, which is an indicator of
the stochasticity of bias, over a wide redshift range 0\le z \le 3. The
cross-correlation coefficient is important to extract information on the matter
density field, e.g., by combining galaxy clustering and galaxy-galaxy lensing
measurements. We compare the simulation results with integrated perturbation
theory (iPT) proposed by one of the present authors and standard perturbation
theory (SPT) combined with a phenomenological model of local bias. The
cross-correlation coefficient derived from the iPT agrees with N-body
simulation results down to r~15 (10) h^{-1}Mpc within 0.5 (1.0) % for all
redshifts and halo masses we consider. The SPT with local bias does not explain
complicated behaviors on quasilinear scales at low redshifts, while roughly
reproduces the general behavior of the cross-correlation coefficient on fully
nonlinear scales. The iPT is powerful to predict the cross-correlation
coefficient down to quasilinear regimes with a high precision.Comment: 12 pages, 6 figures. Maches version published by the Physical Review
