Jonscher [1] [2] studied the diverse dielectric properties extensively by using Fourier transform. The quantum behaviour of dielectricity was deciphered by exploiting the conjecture of fractional change quantization (quantum mechanical dipole moment) [3] - [5] . With this conjecture [3] - [5] , a theory of “quantum dielectricity” is floated [6] . The same theory is further extended by using the Fourier transform. The concepts of electron quanta stretching, twisting and twigging giant magneto resistance (GMR) due to fractional change distribution on twigs and the mesoscopic fractional electric fields due to woven electron strings and their corresponding twigs (sub quanta) in a cavity are evolved [7] - [9] . In this manuscript, the mesoscopic electric fields due to fractional quantization and the quantum mechanical dielectric susceptibility (imaginary part of susceptibility) are theoretically calculated and evidenced with experimental results on barite. The theory is found in agreement with experimental

results. The orientation polarizability, i.e., (where k is the Boltzmann’s constant, T is the temperature in Kelvin and is the total charge, where is the fragmented of fractional charges)

and the deformation polarizibility, i.e., (where is the radial function for a space quantization) are calculated following the quantum theory of dielectricity in Faunja site-typed molecular sieves [10] . The behaviour of quantum capacitance is experimentally evidenced [10] . Dielectric anomalies [11] [12] can be resolved by considering quantum observations [6] [7] [10] .

When a dielectric material at a fixed voltage is subjected to varying frequencies, polarization occurs with different magnitude of energies [1] [2] . The Debye classical model of relaxation deals with the rate equation for the polarization of single dipole floating in a viscous medium, i.e.,

where is relaxation time. But the polarization is directly proportional to electric field.

where is the dielectric susceptibility and E the applied electric field. It is conjectured that electric field is fractionally quantized (quantum dipole moment) in a cavity of a viscus medium [3] - [6] .

where in Equation (4), h is a plank’s constant (quantum action), the polarized displacement, the wave length of photon causing fractional change quantization in a single electron or many electron systems and, º, the congruent operator. With momentum impact, the electron quanta is first stretched, twisted and then twigged. The momentum impact causes the oscillatory energy (quantum action) of the electron quanta to loose energy, as a consequence of which, wavelength of the quanta increases thereby maintaining. The hypothetical wall of the electron quanta behaves like an adiabatic wall. The increase in wave length and decrease in energy or in frequency causes stretching of electron quanta (remember is maintained). When stretching is accomplished, the string of the electron quanta is twisted (Wiener space is transformed in to Wigner space) and then twigged. These twigs are fractional sub quanta on the Lateral surface of an electron string. The total change on an electron remains constant or same but fractionally distributed on twigs [7] . The paradox obeys quantum scattering and indeed the photo electric effect, in the momentum space. The quantum dipole moment is a manifestation of functional charge quantization. The quantum mechanical momentum is a manifestation of fractional charge quantization on their respective sub quanta (twigs).

Due to fractional charge quantization or sub quanta or twigs of an electron string, electric field is also fractionally quantized. Thus Equation (3) changed into

putting Equation (5) in Equation (2), we have

Equation (6) can be transformed into frequency domain by taking its Fourier transform [1] and the final results are

The imaginary part of dielectric susceptibility is considered because it deals with quantum mechanical effects at molecular or atomic level. considering the quantum mechanical time dependent eigenfunction (energy profile),

For our case, the above equation is written as follows

where is the momentum operator, the position operator and E the frequency de- pendent energy. Assume that the time dependent eigenfunction is congruent to polarization at molecule or atomic level.

The time dependent eigenfunction would lead to fractional quantization of electric fields within molecules or atoms. Using

One would have

where is crystal momentum, i.e.,

The fractional quantum electric fields have already been obtained [6] , i.e.,

where stand for fractional quantum numbers, the real permittivity, the imaginary permittivity of the viscus medium (dielectric materials) and h the Planck’s constant. Putting Equation (12) in Equation (11), we have the fractional quantum electric fields has already been obtained [6] , i.e.,

where with our quantum theory of dielectrics [6] ,

where is the fractional charge electronic polarizability and the molecular or atomic level mesoscopic electric field. Using Equation (14) in Equation (13) we have

where r equivalent to displacement due to polarization. Equation (15) and Equation (2) are considered together, i.e., in Equation (13) we have

The relaxation time in classical wave mechanics is defined by We disagree with this notion in quantum

mechanical system. With quantum action, energies oscillate between two arbitrary fixed points at the atomic or molecular level. Atoms or molecules when polarized and fractionally quantized behave like micro wave cavity resonators (mesoscopic fluid resonators) with their sub-quanta or twigs on an electron quanta string or many electron woven quanta string. So, a new definition of relaxation time for quantum behaviour is introduced, i.e.,

Equation (17) shows relaxation time for quantum action of atoms, molecules or ions in the viscous medium and is inversely proportional to applied frequencies. Using Equation (17) in Equation (16), i.e.,

The term is now viscosity independent relaxation time. At quantum level, the Equation (8) is modified for imaginary part of dielectric susceptibility and written like

Equation (19) is obtained by using Fourier transformed with new definition of relaxation time in a mesoscopic cavity resonator with woven electron string and their corresponding twigs (sub-quanta) for fractional charge quantization.

The Equation (18) can be re written in this form

the negative sign for eigenfunction is considered to make the energy profile convergent. The above expression for energy profile at becomes

where is the polarization at zero Calvin temperature, is crystal momentum associated with woven electron strings and their corresponding twigs or sub-quanta. in Equation (20) is the eigenfunction or energy profile for quantized electric fields due to twigs on each of the woven electron quanta strings. Similarly, Equation (18) yields

Taking cube of both sides

Equation (21) is the expression for mesoscopic electric fields due to fractional charge quantization of atoms, molecules or ions only due to woven electron quanta string. This observation is consistent [9] . Considering the term in Equation (22), i.e.,

The negative sign shows quantum wells with woven electron strings of varying lengths in a cavity for mesoscopic electric fields and follows periodicity of (concentric quantum wells). Thus

is the quantum action for each of the quantum well in the cavity and can be normalized to unity with unitary operator.

yields the value of 0.5 which is in between 0.2 and 0.8. Looking close to these numerical values, we can say that yields Gyroscopic constant

Rewriting Equation (21) for molecular field

Now rewriting Equation (21) for, i.e., the imaginary part of dielectric susceptibility

The term has already been interpreted as, i.e., equivalent to. Thus Equation (25) becomes

Taking the cube root of Equation (26) we have

Equation (27) shows that the giant magnate resistance (GMR) [8] appears as constant for imaginary part of dielectric susceptibility i.e.,

Hence, the imaginary dielectric susceptibility in a viscous medium is directly proportional to the cube root of real permittivity and square cube root of imaginary permittivity

where, i.e., the imaginary dielectric susceptibility is considered as quantum dielectric susceptibility for mesoscopic fractionally quantized electric fields in a cavity. The quantum theory of dielectric is extended by using chirp fractional Fourier transform (CFRFT) analysis and applied on experimental results of barite at relatively low temperatures, i.e., and in the frequency range of 1 kHZ. These experimental results are found in conformity with our relatively old quantum theory [6] . The total quantum dielectric susceptibility according to our theory is shown to follow decaying Gaussian profile with respect to fractional quantum numbers is experimentally confirmed on barite in the temperature range and in the frequency range of the polarizabilities of various kinds and the quantum mechanical parameters were determined in Faunja site molecular sieves by using Fermi Dirac statistics and quantum theory of dielectricity, respectively [10] . Dielectric responses [11] [12] can be resolved by considering quantum behaviour [6] [7] [10] .

The mathematical result for electrical susceptibility is obtained in terms of giant magneto resistance (GMR), real permittivity and the imaginary permittivity and the imaginary permittivity, i.e., where

GMR is given in Equation (28), the polarization at zero frequency,

and the polarization at frequency. Mesoscopic fractional electrical field in a cavity of viscous medium (dielectric materials) is produced and responsible for GMR. The theoretical findings are in agreement with experimental results on barite and Fanjasite molecular sieves.
