# Quantum Gravitational Resonator

**Quantum Gravitational Resonator (QGR)** – closed topological object of the three dimensional space, in the general case – ‘’cavity’’ of arbitrary form, which has definite ‘’surface’’ and ‘’thickness’’. To the contrary to the classical case, there are no any gravitational waves and radiation losses in the QGR, but “infinite” phase shifted oscillation of electric-like and magnetic-like gravitational fields, due to the quantum properties of QGR.

## History[edit]

Considering that the theory of the gravitational resonator is based on the Maxwell-like gravitational equations and quantum electromagnetic resonator (QER), therefore the QGR history is close connected with the QER history.

### Electrodynamic resonators[edit]

It is happened, that such physical values as capacitance and inductance have no interest in the modern Quantum electrodynamics. Furthermore, they are neglected even in classical electrodynamics, where electric and magnetic fields are dominated. The point is that, the last are not included in the evident form in the Maxwell equations, and so the resulting solutions includes fields only. Yes, sometimes these coefficients were obtained from the solutions of Maxwell equations, but it were very rarely, and relation to them were consideringly low. It is known too, that s.c. “field approach” in electrodynamics that considered “point charges” leads to the “fool infinities”, when the interaction radius trends to zero. Furthermore, these “fool infinities” are presented in the quantum electrodynamics too, where power methods are developed to compensate them. Contrary to the theoretical physics, the applied physics are widely used reactive parameters, such as capacitance and inductance, firstly in the electrotechnics and then in the applied radiotechnics. Now reactive parameters are widely used in the information technologies, which are based on the generation, transmission and radiation of electromagnetic waves of different frequencies.

The present day situation (without proper development of the theory of reactive parameters such as inductance, capacitance and electromagnetic resonator) brakes developments of information technologies and quantum computing. Note that, mechanical harmonic oscillator was considered in quantum mechanics in the early 30-ies of 20-th century, when the quantum theory is developed. However, the quantum consideration of the circuit was started only by Louisell(1973) ^{[1]}. Since then, there were no practical examples of the *quantum* capacitance and inductance, therefore this approach did not obtain proper consideration. Theoretically correct introduction of the *quantum capacitance*, based on the density of states, first was presented by Luryi (1988) ^{[2]} for QHE. However, Luryi did not introduce the quantum inductance, and this approach was not considered in the quantum LC circuit and resonator. Year later, Yakymakha (1989) ^{[3]} considered an example of the series and parallel quantum circuits (its characteristic impedances) during QHE explanation (integer and fractional). However in this work did not considering the Schrodinger equation for the quantum LC circuit.

For the first time, both quantum values, capacitance and inductance, were considered by Yakymakha (1994) ^{[4]}, during spectroscopic investigations of MOSFETs at the very low frequencies (sound range). The flat quantum capacitances and inductances here had thicknesses about Compton wave length of electron and its characteristic impedance – the wave impedance of free space. And three year later, Devoret (1997) ^{[5]} presented complete theory of the Quantum LC Circuit (applied to the Josephson junction). Possible application of the quantum LC circuits and resonators in the quantum computation are considered by Devoret (2004) ^{[6]}.

### Gravitational resonators[edit]

Due to McDonald^{[7]} first who used Maxwell equations to describe gravity was Oliver Heaviside^{[8]} The point is that in the weak gravitational field the standard theory of gravity could be written in the form of Maxwell equations^{[9]} It is evident that in 19-th century there was no SI units, and therefore the first mention of the gravitational constants possibly due to Forward (1961)^{[10]}

In the 80-ties Maxwell-like equations were considered in the Wald book of general relativity^{[11]} In the 90-ties Kraus ^{[12]} first introduced the gravitational characteristic impedance of free space, which was detaled later by Kiefer ^{[13]}, and now Raymond Y. Chiao^{[14]} ^{[15]} ^{[16]} ^{[17]} ^{[18]} who is developing the ways of experimental determination of the gravitational waves.

## Classical gravitational resonator[edit]

In the general case classical gravitational resonator (CGR) is the *cavity* in the 3D-space. Therefore, CGR has infinite resonance frequencies, due to the three dimensions.

To the contrary of classical gravitational LC circuit, both electric-like and magnetic-like gravitational fields are displaced in the same volume of CGR. These oscillating of electric-like and magnetic-like gravitational fields in the classical case are like *standing waves*, that form gravitational waves, that could be radiated in the external world.

### Gravitational LC circuit[edit]

Gravitational voltage on gravitational inductance is:

Gravitational current through gravitational capacitance is:

Differentiating these equations with respect to the time variable, we obtain:

Considering the following relationships for amplitudes of "voltages" and "currents":

we obtain the following differential equation for gravitational oscillations:

Furthermore, considering the following relationships between "voltage" with "charges":

and "current" with "magnetic flux":

the above oscillation equation could be rewritten in the charge form:

This equation has the partial solution:

where

is the resonance frequency, and

is the gravitational characteristic impedance.

Note that, in the general case the *gravitational charge*() has the same dimensions as the *gravitational mass* (). For the sake of completeness we need to present the third differential equation for "rotor gravitational mass" (or flux) in the form:

where the following relationship between gravitational current and *magnetic-like gravitational flux* is considered:

## Quantum general approach[edit]

### Quantum gravitational LC circuit oscillator[edit]

Inductance momentum quantum operator in the electric-like *gravitational mass space* could be presented in the following form:

where is reduced Plank constant, is the complex-conjugate momentum operator. Capacitance momentum quantum operator in the magnetic-like *gravitational mass space* could be presented in the following form:

where is the *induced magnetic charge*. Considering the fact, that there are no free *magnetic-like gravitational masses*, but it could be immitated by *electric-like gravitational mass current* ():

we can introduce the third momentum quantum operator in the current form:

These quantum momentum operators defines three Hamilton operators:

where is the resonance frequency. We consider the case without dissipation (). The only difference of the *gravitational charge spaces* and *gravitational current spaces* from the traditional 3D- coordinate space is that it are one dimensional (1D). Schrodinger equation for the gravitational quantum LC circuit could be defined in three form:

To solve these equations we should to introduce the following dimensionless variables:

where is scaling "induced electric-like gravitational charge"; is scaling "induced magnetic-like gravitational charge" and is scaling "induced electric current". Then the Schrodinger equation will take the form of the differential equation of Chebyshev-Ermidt:

The eigen values of the Hamiltonian will be:

where at we shall have *zero oscillation*:

In the general case the *scaling charges* could be rewritten in the form:

where

where is the Planck mass, first proposed by George Johnstone Stoney (1881), before the quantum theory was created.. This mass scale is now called the *Stoney scale*. Other designations are as follows: is the Planck mass, first proposed by George Johnstone Stoney (1881), before the quantum theory was created.. This mass scale is now called the *Stoney scale*; is the gravitoelectric permittivity (like *electric constant*); *G* is the gravitational constant, *c* is the speed of light in a vacuum, and is the gravitomagnetic permeability (like *magnetic constant*); is the Planck's constant, is the electric fine structure constant for electric charge quantum - (electron charge)

These three equations (4) form the base of the *nonrelativistic quantum gravidynamics*, which considers elementary particles from the **intrinsic** point of view. Note that, the standard quantum electrodynamics conciders elementary particles from the **external** point of view.

#### Planckion as quantum oscillator[edit]

Suppose that planckion has its mass defined by the quantum oscillations. Thus, its mass will be equivalent to the *zero oscillations* of the quantum gravitational LC circuit:

So, the oscillation length will be:

where is the Compton wavelength of planckion. Further, let us consider that this gravitational mass is uniformly distributed on the sphere:

- .

Then we can find out the density of states for this mass:

Thus, presentation of the planckion gravitational mass as the *zero oscillation* of the harmonic oscillator yields to the uniform its distribution on the sphere or the radius.

#### Graviton as quantum oscillator[edit]

As is known, graviton momentum is defined as:

where is velocity of light. So, the "effective (energy) graviton mass" could be defined as:

Then the length scaling parameter of harmonic oscillator will be:

where is the graviton wavelength.

### Gravitational resonator as quantum LC circuit[edit]

Due to Luryi density of states (DOS) approach we can define gravitational quantum capacitance as:

and quantum inductance as:

where resonator surface area, two dimensional (2D) DOS, electric-like gravitational mass (or flux), and magnetic-like gravitational mass (or flux). Note that these fluxes should be defined afterward.

Energy stored on quantum capacitance:

Energy stored on quantum inductance:

Resonator angular frequency:

Energy conservation law:

This equation can be rewritten as:

from which it is evident that these "gravity charges" are the *fluxes*, but not *metallurgic charges*.

Characteristic gravitational resonator impedance:

where magnetic-like gravitational flux quantum. Considering above equations, we can find out the following electric-like and magnetic-like set of gravitational induced fluxes:

Note, that these values are not the real "metallurgic charges", but the maximal fluxes, that maintain the energy balance between resonator oscillation energy and total energy on capacitance and inductance

Since capacitance oscillations are phase shifted () with respect to inductance oscillations, therefore we get:

where is oscillation period.
