Crystalline Quantum Oscillators: The Boson's Mate in a Sea Of Fermions: Elemental Composition

Timothy J. Sipp                                                                                                                                                            07/27/16

The VAPER-ARC Reactor doesn't violate the laws of thermodynamics because according to the Pauli Exclusion Principle and Fermi-Dirac Statistics for fermions each electron formed in the electron orbital vacancy in the crystal lattice has a separate thermodynamic relationship with the quantum oscillating reservoir. The Fermi energy of the electron is an order of magnitude higher than the thermodynamic energy and doesn't become equivalent until reaching the Fermi temperature which is two orders of magnitude higher than room temperature. The three quantum vortices in the valence band are associated with each of the three quasi-particle wave functions that comprise the composite fermion defined by these spinon, holon, and orbiton wave functions. The product is an electron to replace the previous electron at the most desired energy level within the quantum oscillator crystal lattice.

The valence band inside single crystal Aluminum-Nitride piezoelectric chips act as quantum condensers providing the ideal boundary conditions to stimulate wave-function resonance of the quasi-particles that comprise electrons: the holon, spinon and orbiton. The valence band in the crystal lattice structure releases the existing free electron when stress is applied. A free electron reappears in the crystal lattice structure when the pressure is released and the crystal retakes its original shape. The question remains, how does the release of pressure on the crystal replace the released electron in its crystal lattice structure.  Immediately after the electron vacates the valence orbital another uncondensed electron condenses from the harmonic resonance of the three wave functions represented by the three remaining quantum vortices. 

You could also imagine water dripping slowly from a vertically suspended chilled sponge on a humid day.  There is water in the sponge and it is flowing slowly towards the bottom due to gravity, viscosity, and the Bernoulli and the Coanda effects. The water isn't visible until it hits a critical point where it gathers due to gravity and cohesion at the corner of the sponge (Condenser ) and the forces of gravity and cohesion form a drop that shears from the rest of the water and the sponge and is now its own thermodynamic system with mass and energy. Leaving the sponge in a new state of non-equilibrium, a quantum vacuum driving the precipitation of an electron from the sea of fermions in the quantum field.  

In the VAPER-ARC Reactor the oscillating gas stimulates the bulk modulus of the piezoelectric crystal. The Crystal will compress and expand sympathetically as the frequency and pressure vary in the gas. Each cycle of vibration the crystal emits free electrons from the bonds in the lattice. Each cycle of vibration after the electron is pushed out of the lattice there is a negative quantum pressure localized within the orbital for that electron. The release of localized deformation allows the crystal lattice to go back to normal maximizing the negative quantum pressure. Like a catalyst often provides context and construct to make a process more efficient these quantum oscillators have the natural resonant frequencies conducive to harnessing the wave functions of the quasi-particles that make electrons .

Again, the valence bands of the aluminum-nitride crystal are the breeding grounds for electrons. Electrons are condensed matter formed by the superposition of the three quasi-particles that make up electrons; the holon that presents charge, the spinon that presents spin and the orbiton that presents path. As pressure fluctuations in the gas stimulate pressure fluctuations in the crystal there is a collective excitation of bosons within the crystal as the waves propagate forcing free electrons (fermions) out of the crystal creating a negative quantum pressure attracting the  fermions necessary to make another electron in the valence band. This is semi-conductor electrons and holes science & technology taken to a new level of power.

Current nuclear fusion work relates to using much larger composite fermions like Deuterium and Helium to generate electricity by generating heat that generates steam to drive turbines that generate electricity. By understanding the actual process of piezoelectricity we may have discovered solid state cold fusion at much lower energy levels.  Current theory states that electrons are elemental fermions, a class of leptons that follow the Pauli Exclusion Principle. Even though electrons are half integer spin "elemental" fermions with negative charge, they can be precipitated by compositing their three quasi-particle wave functions in a quantum oscillator crystal lattice to mass produce electrons which by definition have individual thermodynamic relationships with the quantum reservoir but retain the spin, charge, and orbit of the previously produced electrons.

Again, the VAPER-ARC Reactor's 6th Order non-linear passively-mechanically amplified high amplitude sound waves are stimulating the bulk modulus of the crystals that act as quantum energy condensers and pumps providing a supply of electrons for the useful lifetime of the crystals (4% loss of energy conversion efficiency every 10 years). The high frequency high voltage static electric discharge is then conditioned through multi-phased coupled inductors and transformers for immediate use or storage. Large sensor based systems experience line noise and electron drift that can set up resonance and harmonic currents. We have designed a system that capitalizes on these phenomenon instead of mitigating them. We are "fusing" the fermion wave-functions of an electron into an electron in the quantum wells of the aluminum-nitride crystals that are driven and pumped by the passively mechanically amplified acoustic waves.

This is mass manufacture of electrons analogous to injection molding in macroscopic manufacturing. Many questions remain: first, is the hysteresis of the set of three quantum vortices the "mold" dictating the spin, charge, and path of subsequent electrons? Second, can these manufactured electrons become entangled with others in a super-lattice and change signs and spin? What does that look like? Three, can we make adaptive heterogeneous complex crystalline mono-block systems with power generation, heat management and logic structures? The answers to these questions represent the beginning of a new era in understanding ourselves, the energy we use and the cosmos to which we belong.

Dr. João Magueijo

The direct link to your Variable Speed of Light (VSL) Theory is this I think: If the universe is expanding as light slows down forcing the quantum vacuum to shed energy in the form of condensed matter that is expanding away from itself, is there a predicted local quantum pressure that could explain the rate of mass manufacture of electrons in large mono-crystalline piezoelectric chips. In essence, could my machine present the needed verifiable quantitative measurements of quantum energy being condensed to support the VSL?

I just watched your documentary "Einstein's Biggest Blunder" and I realized that by generating such vast localized power that we would indeed be bending space-time while increasing the energy density at high frequencies. The higher energy density in the direction of motion and the lower energy density behind the vehicle would necessarily alter the local speed of light with reference to the warp bubble and space-time itself, but what about inside the warp bubble? Are we fundamentally turning a vehicle into a massive high energy fermion and quantum tunneling through space-time?

If so, is gravity really the driving force behind cosmological movement or is the electric universe and VSL responsible? Is mass a quantum illusion and gravity an artifact of temporal interaction? Does the Higgs Field endow Time instead of Mass? Is condensed matter physics barking up the wrong tree?

Declarations



The following material supports my claims regarding the operability of the present invention and includes screen shots of the data and test setup for the computer models. Furthermore, as assistance was rendered by a National Laboratory via the New Mexico Small Business Assistance Program, the engineer who built the computer models is contractually disallowed from swearing an affidavit that could be seen as product promotion.
 

To answer the false allegation of inoperability due to a perceived violation of Thermodynamics, I have prepared a brief primer on the electro-quantum dynamics of the piezoelectric effect as electronic fusion. The short answer is that much like vacuum tubes were the first electrical amplifiers that used thermionic emission to increase electrical power without violating Thermodynamics due to their degradation as the material of the hot cathode deteriorated, so to does the present invention lose efficiency in transduction through a gain medium embodied by piezo-ceramics as the piezoelectric materials lose approximately four percent (4%) of their power translation abilities every ten years. The degradation of the piezo-ceramics is increased if the system is operated at its maximum power levels.
 

The present invention does not violate the Laws of Thermodynamics, much like vacuum tubes did not and solid state amplifiers do not, but it is the most efficient way of harvesting resonant energy across several interacting, reinforcing systems. And just like everything else it will eventually stop working as designed and require routine maintenance to include fresh piezoelectric ceramics and the moving parts and their housings degraded by wear. Thank you.
