QUANTUM PHYSICS, ABSTRACT QUANT-PH/9510004 From: "Jun Liu" 
Date: Thu, 5 Oct 1995 04:30:27 -0400
The Real Significance of the Electromagnetic Potentials Author(s): J`un L'iu
The importance of the potential is revealed in a newly discovered effect of 
the potential. This paper explore the same issue introduced in quant-
ph/9506038 from several different aspects including electron optics and 
relativity. Some people fail to recognize this effect due to a wrong 
application of gauge invariance.

In the above two papers, Dr Liu proposes a theory of the electromagnetic 
potential which is a radical extension of the well known Aharonov-Bohm effect. 
In the second paper he is barely able to contain his frustration about 
repeated publication rejections over the last four years from leading physics 
journals. He provides a theoretical foundation for his potential theory, as 
well as some relatively straight forward suggestions for experiments which 
might confirm the theory. But there is an enormous problem. Liu's theory 
violates the concept of invariance of physical parameters under an 
electromagnetic gauge transformation. Electromagnetic gauge invariance is a 
cornerstone in the foundation of quantum theory and QED, and it is also part 
and parcel linked with the dogma of light speed invariance. In other words, 
heresy.

The AB effect is invariant under an electromagnetic gauge transformation. 
While a phase-shift occurs in the AB effect, it can be identified only over a 
closed path and is impossible to identify with any specific "local" region of 
space. Furthermore, in the AB effect, there is no interaction relating to a 
transfer of energy or momentum. Maintaining the idea of gauge invariance is a 
little harder to do in the Aharonov-Casher effect, but it can be accomplished 
by "gauging away" the physical effects of magnetic spin precession by using a 
combination of factors from the classical Maxwell fields along with the 
electromagnetic potential. It has the look of an elaborate parlor trick, but 
so does most of QED. 

Liu's theory predicts that the electromagnetic potential acts like a kind of 
"refractive index" to wave propogation, and is similar in some respects to 
what was predicted in the earlier paper on electron optics by Ehrenberg and 
Siday in 1949. The result is that in some circumstances an electromagnetic 
potential causes a change in wavelength, and in other circumstances causes a 
change in phase (AB effect). An effect on wavelength would be manifested as a 
change in the envelope of the interference pattern, rather than merely a shift 
in the pattern. In Liu's theory an exchange of energy and momentum becomes 
possible. His theory is relatively easy to test and verify, but oddly or not, 
no one has yet done so. Maybe because we already "know" it can't be true? 

One interesting prediction of Liu's theory is that electromagnetic potential 
will result in time dilation. He doesn't appear to be aware that there is 
already experimental evidence that this occurs. See references to inventions 
and experiments by people such as Saxl, Barker, and Keller, which demonstrate 
time dilation in an electric potential. Time dilation can be viewed 
equivalently as a shift in wavelength. Liu wishes for someone to conduct an 
experiment to test for a change in wavelength by using a quantum 
interferometer. A fine idea. But what about those experimenters who have 
already measured this effect with a clock? Also see a variety of references 
here to theories and experiments which relate the scalar electric potential to 
the gravitational field, and time dilation is a well know, and experimentally 
verified, prediction of general relativity. 

The Aharonov-Bohm effect has sparked a revolution in physical thought. There 
are a variety of new ideas and experiments, such as verification of Liu's 
theory, which could soon begin to fan it to a flame. When the flame becomes 
sufficiently illuminating, watch the political scientists begin to scramble 
for a comfortable seat nearer the fire. -- Robert Stirniman

Time out for a summary.

. Hooper, as well as Carr, Rognerud, Jefimenko, et al, find that a 
electromagnetic effect which is not shieldable, and hence difficult to 
distinguish from gravitation, results from equal and opposite electric 
currents (dipole-current), and that a similar effect can also be generated by 
a moving magnet or a moving electric current. 

. Recent experiments in Tampere Finland, discover a gravitational 
shielding effect from a levitated rotating superconductor disk. This is 
similar in some respects to Hooper's invention, with the equal-and-opposite 
electric current being generated in a superconductor disk via the Meissner 
effect.

. Sansbury, Volkov, Brown, Teller, Blackett, Zollner, et al, provide 
theoretical arguments as well as some experimental indications that equal-and-
opposite electric charge (dipole-charge) is similar, or equivalent, to a 
static gravitational field. And that alignment of electric dipoles in matter 
and in vacuum polarization, can result in a force which is not shieldable, and 
not easily distinguishable from gravity. Conversely, it is well know that a 
gravitational field, an acceleration, or a mechanical force, causes a dipole 
moment (polarization) to occur within a dielectric material.

. Wallace, Laithwaite, Barnett, et al, discover that gravitational 
and electromagnetic field effects occur due to alignment of the microscopic 
spin of quantum particles with the angular momentum spin axis of a larger 
macroscopic body.

. Aharonov and Bohm discover that an effect can occur on an electrically 
charged particle due to the magnetic vector potential, in regions of space 
where the classic Maxwell fields vanish. Originally -- on the outside of 
infinitely long solenoid coil (with the magnetic field cancelled by equal-and-
opposite currents). Others have conducted this experiment using a toroidal 
coil coated with superconductor material (generating an equal-and-opposite 
current) to cause the Maxwell magnetic 
field to vanish. A similar effect, Aharonov-Casher is disovered to occur due 
to the electric scalar potential, in regions of space where the Maxwell 
electric field vanishes.

. Whittaker, and Eherenberg and Siday, have written theories which 
are precursors to Aharonov-Bohm, suggesting that the electromagnetic potential 
is a far richer and more fundamental thing than the Maxwell fields. The 
classical Maxwell fields are regarded as artifical abstractions. We can also 
note that Maxwell's theory itself, was originally much richer in variables (20 
equations and 20 unknowns), before it was simplified by Gibbs and Heaviside, 
to the vector formlation which we know as "Maxwell's" equations. 

. Vu Ho authors a recent paper suggesting experiments relating the 
electromagnetic potential and the Aharonov-Bohm effect to gravitation. And in 
a more recent paper, using the mathematics of differential geometry and 
general relativity, Dr Ho demonstrates that gravity can be expressed 
mathematically as a coupling of two equal-and-opposite electromagnetic fields.

. Jun Liu authors recent papers suggesting that the electromagnetic 
potential is of paramount importance. Liu's theory predicts that "local"
effects can result from the potential in regions where the Maxwell fields 
vanish -- a violation of the theory of invariance under electric gauge 
transformations. Liu theory predicts that time dilation will occur in an 
electric potential. Saxl, Barker, and Keller have conducted earlier 
experiments which demonstrate time dilation in an electric potential.
