Quantum theory with conjecture of fractional charge quantization, eigenfunctions for fractional charge quantization, fractional Fourier transform, Hermite function for fractional charge quantization, and eigenfunction for a twisted and twigged electron quanta is developed and applied to resistivity, dielectricity, giant magneto resistance, Hall effect and conductance. Our theoretical relationship for quantum measurements is in good conformity and in agreement with most of the experimental results. These relationships will pave a new approach to quantum physics for deciphering measurements on single quantum particles without destroying them. Our results are in agreement with 2012 Physics Nobel Prize winning Scientists, Serge Haroche and David J. Wineland.
Quantum Resistivity Quantum Dielectricity Giant Magneto Resistance Quantum Hall Effect and Conductance1. Introduction
Experimental results in quantum physics since last three decades brought significant changes in our under- standing. The discovery of quantum Hall effect in heteorostructure semiconductors results in the Nobel Prize winning award for the year 1987 to Von Klitzing [1] . With this discovery, the experimental results of quantum conductance are reported by Van Wees et al. [2] in the two dimensional electron gas of a GaAs-AlGaAs heteorostructure. The visible range photons used to illuminate water molecules are studied with absorption and Fourier transform infrared spectroscopies [3] . The biological specimens are also considered for chromotherapy [4] - [7] . A new conjecture of fractional charge quantization with newly developed theory is coined to look into the shape of eigenfunctions, determine the energy eigenvalues and validate the quantum scattering [8] . Mean- while, new experimental results on giant magneto resistance (GMR) to enhance storage capacity with charges are reported. This discovery of GMR led Albert Peter and Paul Gruebber to win the Nobel Prize for the year 2007 [9] . During the last decade (2000-2010), surprising results are noticed on dielectrics and dielectricilty. A new quantum theory, with our conjecture of charge quantization, on dielectricity is presented in which we modify the Clausius Mossotti and Debye equations [10] . The same quantum theory of dielectricity is applied on Faujasite-type molecular sieves and on dolomite [11] [12] , respectively. The quantum theory of dielectrics and dielectricity is further extended and modified by using Hermite function for fractional quantum states and fractional Fourier transform .
Now, we witnessed again new exciting experimental results on individual quantum systems which led the Nobel Prize winning award in physics by Serge Haroche and David J. Wineland in the year 2012. We studied American Institute of Physics (AIP) reports of 2012 prize winning award and all relevant research papers [13] - [21] . Most of the experimental results of physics Nobel Prize winners like Von Klitzing, Albert Peter and P. Gruebber, Haroche and Wineland fit to our “conjecture of fractional charge quantization” and indeed “theory”. A new theory is described “how charge being a constant entity, on anelectron in the momentum space is fractionally quantized while interacting with a photon, with twisting and twigging effects of an electron quanta” [22] [23] . The eigenfunction for an electron quantum wire or string with sub-quanta (twigs) on its lateral surface at different locations namely above its surface, at the surface and within the sub-quanta and the electron string with beaded fractional quantized states for the fractional charges are determined [23] .
2. Results and Discussions
The fractional Fourier transform (FRFT) of order of is defined by Almeida [24]
where is a rotational angle in the time-frequency plane, and is the FRFT operator. For the kernel coincides with the kernel of Fourier transform (FT). Saleem Iqbal et al. developed fractional Fourier integral theorem and fractional Fourier Cosines and Sines transforms [25] . [23] developed Hermite function for the fractional quantum states, i.e.,
Equation (2) is consistent with other definitions of Hermite polynomials. Saleem Iqbal [21] obtained the eigenfunction for a twisted and twigged electron quanta by using Equations (1) and (2), i.e.,
Equation (3) represents plane wave for a rotation vector alpha (discussed in [21] ) for all corresponding fractional quantum numbers, i.e.,
We shall use Equations (1)-(3) and relation (4) to obtain interesting results for different cases of physics problems.
2.1. Case I―Quantum Resistivity
We know that the electrical resistivity is the inverse of conductivity. The electrical conductivity according to Drude Model (classical) is defined as:
where n is the number of charge carriers, e the charge of an electron, the relaxation time and the effective mass of an electron. With the advent of single electron transistors (Spintronics), one could expect quantum conductivity across the interface states. The single electron tunneling will follow a helicon profile with each turn of the helix corresponding to fractional quantum states (charges are fractionally distributed on sub- quanta, i.e., twigs). Changing n with (Equations (2) and (4)), e with and
with, , , and in Equation (5), we have
where is fractional wave number. can be determined from Raman spectroscopy [26] . can be
determined from relative heights of Raman peaks. The helicon profile of an electron is due to spinning or gyroscopic motion. To our conjecture, the dual nature of a quantum particle is a metaphoric states, i.e., it simultaneously behaves as particle and quanta. The fractional quantized state of charge in the momentum space are the manifestations of gyroscopic constant,. Equation (6) shows that the quantum conductivity follows periodicity of fractional quantum numbers,. i.e., and is inversely pro- portional to quantum action (energy becomes oscillatory). The quantum resistivity is the inverse of quantum conductivity, i.e.,
Remember that the conductivity is different from conductance.
2.2. Case II―Quantum Dielectricity and Giant Magneto Resistance (GMR)
The mesoscopic fields in a cavity are the manifestations of quantum mechanical dipole moments (fractional charge quantization to a single electron or many electrons systems) due to either molecules, atoms, ions or even the charge, being a constant physical entity, of an electron in the momentum space while interacting with photons. To our conjecture the quantum mechanical dipole moment is a fractional charge quantization, i.e.,
whrer D is the displacement of charge either on an electron or in many electrons system, the wavelength of the interacting photons and “º” congruent operator. Using fractional Fourier transform (FRFT), Hermite function for the fractional quantum states, i.e., Equations (1) and (2), quantum mechanical dipole moment [Equation (8)] and the quantum theory of dielectric suscaptibility is obtained with a constant [27] . The constant is ascribed to giant megneto resistance is discussed and the calculation of quantum electric susceptibility of dielectric material with particular reference to mesoscopic fields in a cavity is established in [27] [28] , i.e.,
where is the polorization in a cavity at zero kelvin, , the quantum electron polorizability (orientation of sub-quanta (twigs) of an electron string or wire either due to single electron or many electrons system), the molecular field inside the cavity, gyroscopic constant (0.02 - 0.08),; the real permittivity and the imaginary permittivity. They ascribe the constant the GMR, i.e.,
The most attractive quantum electrodynamic potential of an electron or electron quanta (the interior of which is envisaged as a potential well and is defined by the strength of the quantum well)
where is the reduced mass of electron (equivalent to quanta of electron), is the radius of electron varying with the depth of the quantum well and is the fractional quantum numbers corresponding to varying strips of the depth of quantum well. GMR is associated with quantum electrodynamic (QED) potential in a cavity with mesoscopic fields preferably due to fractional charge quantization. The concept of quantum capacitance is also floated [11] which follows the shape/profile of Gaussian tail. The fractional charge quantization if oriented in a preferential direction will results in to GMR.
2.3. Case III―Quantum Hall Effect (QHE)
The megnetoresistance in quantum Hall effect should depend on magnetic field when an electron (charge as a constant physical entity) is fractionally quantized with twisting and twigging of an electron quanta. This is why we are interested in quantum Hall effect on heteorostructure semiconductors by Von Klitzing [1] . The electric
field is fractionally quantized with a gap of quantum Hall resistance, i.e.,. To our under-
standing, this resistance is a manifestation of twisting and twigging effects of an electron quanta. This is visible
in our Equations (9) and (10), with a gyroscopic constant, , i.e.,. Magnetoresistance is of two
types, one is longitudinal and the other is transverse. The longitudinal magnetoresistance is associated with magnetic field parallel to the current. The excitonic quantized Hall state at total Landau level filling factor is unity with longitudinal component vanishing and Hall component developing. The Lorentz force, in QHE, for a single electron, is
Changing with, i.e., electric field due to fractional distribution of charges in sub quanta or twiggs on
an electron wire or string, with, with where is the energy due to sub-quanta of an
electron and with where is the relaxation time for twiggs on an electron wire. After simplification of Equation (12) with substitutions, the quantized Lorentz force due to single electron is
where, is an integrated vibrational frequency of each of the twigs at different fractional
quantum numbers, i.e.,. In quantum Hall effect, the current is not independent of time because the fractional charge in their corresponding sub-quanta (twigs) of an electron is dependent on twisting time or energy operator. Thus, we change the following relationships of classical Hall effect, i.e.,
Using eigenfunction for an electron (Equation (3)) in Equation (15), we get two sets of energy eigen- value equations
where is rotational angle of FRFT ((defined in Equation (1)) in (time, frequency) plane. Equation (16) can
be solved by considering and as Hermitian Hamiltonian operators. The cyclotron frequency for each of sub-quanta, i.e., twigs) on the lateral srrface of an electron string will be different from each other despite the fact that they are integrated on a lateral surface of an electron wire, as a consequence of which, we shall encounter GMR. The twisting time of an electron quanta for each sub-quanta will vary. This shows that will also vary with different rotation angles and with the frequency of each sub-quanta. The classical Hall coefficient usually depends on the number of charge carriers and also on moderate to high magnitude fields. For QHE, the Hall coefficient becomes insignificant due to single electron and due to fractional charge quantization either on a single electron or many electron system. The GMR is enhanced, especially due to the transverse component of the magnetic field. Therefore, it is suggested that the Hall coefficient in QHE should be replaced by drag coefficient or resistance known as quantam Hall resistance,. i.e., the drag resistance is quantized in terms of. The classical cyclotron frequency is defined as:
e is changed with, with and c with. is also changed with in Equation
(17). After substitutions and simplifications, Equation (17) is changed in to quantum cyclotron frequency for each of sub-quanta on the lateral surface of electron wire, i.e.,
With resonance Raman Scattering in the fractional regime, and can be easily determined.
2.4. Case IV―Quantum Conductance
Quantum conductance was first experimentally observed by Wees et al. [2] . They observed that the
conductance did not increase continuously but rather in quantized steps of, where h is Planck’s constant.
When the electronic mean free path of a wire exceeds the wire length, the wire behaves like an electron wave guide. Each wave guide mode or channel (ballistic conductors) contributes an amount to the total conductance of the wire, i.e.,
where is the quantum Hall resistance, i.e,. Usually, we know that the combined
effect of Ohemic resistance and dynamic resistances (capacitive reactance and inductive reactance) is called impedance. The inverse of the impedance is termed as admittance. To our opinion, the inverse of the quantum Hall resistance is quantum conductance thus Equation (19) is modified as
We consider the current density j equal to current I,. i.e., , where v is the velocity of electron, and are chemical potentials connecting the two reservoirs adiabatically for a one dimensional wire and e the charge of an electron. Since is the electromotive force to drain the current in between the two reservoirs and V is equal to voltage. The resulting conductance G will be determined as follows:
With our conjecture of fractional charge quantization, change e with, v with, with, c
with, we get the modified definition of
where is the velocity of sub-quanta or twigs on the lateral surface of an electron string or wire. Looking carefully Equation (23) and comparing with Equation (21), can be regarded as conductance for fractional quantized charges on sub-quanta. The current density or current due to twigs (sub-quanta) on the lateral surface of an electron wire, according to our calculations is now defined by the following relationship
where is the fractionally quantized frequency of twigs. Equation (24) can be calculated for data from resonant Raman scattering in the fractional Hall regime. The velocity in Equation (23) for each of the twigs on the lateral surface electron wire can be determined from cyclotron frequencies of the corresponding twigs and, of course, with resonant Raman Scattering.
3. Conclusion
