Dear László-Attila

Thank you for your comment.

Consider a photon that is moving with enough energy and is converted to the "electron-positron" pair in striking with a heavy nucleus. The produced pair includes two particles one of them with positive electric charge and another one with negative electric charge. These two particles participate in two interactions with each other. One of them is gravitational interaction and another one is electric interaction. According to quantum mechanics theory, these interactions are done through exchanging of particles. Electromagnetic exchange particle is photon that carries

electromagnetic force and gravitational exchange particle is graviton that carries gravitational force. Now, some essential questions is proposed:

1- How charged particles are produced from a neutral particle?

2- From what and how exchange particle (photons) is produced?

Dear Dmitry

Yes, you are right. Question is how a charged particle produces electric field?

dear mr javadi

hope this information could help

Dear mohd arinal b abd halim

Thank you for your interesting comment. I knew them, in generally classical and quantum electrodynamics do not describe how a charged particle produce it field.

In quantum electrodynamics (QED) a charged particle emits exchange force particles continuously. This process has no effect on the properties of a charged particle such as its mass and charge. How is it explainable? If a charged particle as a generator has an output known as a virtual photon, what will be its input?

Dear Dmitry

This discussion is not about the photon radiation (EM).

In quantum field theory, forces are transmitted by particles, and fields are associated with particles which transmit the forces. The particles of the electromagnetic field are the photons. In quantum electrodynamics all electromagnetic fields are associated with photons, and the interaction between the charged particles occurs when one charged particle emits a virtual photon that is then absorbed by another charged particle. The photon has to be a virtual photon, because emission of a real photon would violate energy and momentum conservation.

In other word, if a charged particle as a generator has an output known as a virtual photon, what will be its input?

Dear Hossein Jabadi,

Thank you for response… I have understood your (good) example and your questions… Your question is referring to QED interpretation… I am only laic in the discussed theory… But thanks for your very clear explanation I have had luck to understand where you are… and accept your explanation… The QED cannot respond to your question, but the classical electro-dynamics can… That is why can be stated that QED in actual form does not work…   These situation can be resolved if we eliminating from theory the quantification of electro-magneto-gravito  force, only with a basic criteria (under atomic level and not atomic level …- J know you are more able to make such a criteria like me…

I have read your paper: ” Modern physics; problems and solutions”.. It is excellent!( I think in Europe for such work you can lose your job , if the company leader are democratic liberals, in 1995 I lost my job for a philosophical book , after 3 months of publication)… Can be annexed to your work another theory Plate Tectonics… even if in geology-planetology you can catch easier the understanding of those processes  which act in planetary scale…

The geology is a most important place for testing of physical theory!

 Dear László-Attila

Thank you for explanation. Let me continue with a quote of Kierkegaard.

“What if everything in the world were a misunderstanding, what if laughter were really tears?”

Is all about virtual particles (also exchange particle) misunderstanding in QED? My answer is no, if we ignore the exchange of particles, fields description (QFT) will be impossible.

As you know; "The idea of an exchange force implies a continuous exchange of particles which accompany the interaction and transmit the force, a process that receives its operational justification through the Heisenberg uncertainty principle."

I have not invented virtual photon, I have showed that how thier properties should be and how they work.

Article Graviton and virtual photons

Basic physics teaches that an accelerated charged particle (like an electron) radiates electromagnetic waves. Acceleration occurs by either speed or direction change.  Antennas are designed to enhance charge radiation along their extent, preferably a wavelength or more. A generator, of course, is required.

Incoherent radiation arises based on the blackbody law that states that any object above absolute zero in temperature radiates, albeit noise.  The hotter the body the higher the continuum of radiation extends up the spectrum.

Dear Warren

Thank you for your mention, it is right. Please consider that this discussion is related to process of production electric field by charged particle. Question is how a charged particle produces its electric field.

Best Regards

In the general case electromagnetic radiation is direct consequence of motion of electric charges which can be described by D'Alembert equation (DA) or by Maxwell equations that are consequences of DA.

Dear Marat

Maxwell equations (and QED) do not show how a charged particle is produced electric field, this issue is related to electric field, not to radiation.

Dear Hossein

I have to insist: it is well known that just non-inertial motion of charged particles (current) produces electromagnetic radiation because "current" is right part of D'Alembert equation.

Dear Marat

As you know electromagnetic radiation is a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously. My question is referred to electric field around the charged particles.

According to the experimental observations, I generalize the Maxwell equations of electromagnetism to the gravitational field. I have used the pair production and decay to show that a charged particle acts like a generator, the generator input and output are gravitons and virtual photon. The negative charged particle produces positive virtual photon and positive charged particle produces negative virtual photon. A negative and a positive virtual photon combine with each other in the vicinity of a charged particle and cause the charged particle to accelerate. Although this approach to Quantum Field Theory (QFT) is presented, it has some differences. The mechanism of negative and positive virtual photons interaction is easier and more realistic than exchange particles of QFT, and it also has no ambiguities of QFT. After all, I explain the real photon and its structure by using the virtual photons.

Hi Hossein:

You keep asking about electric fields, but all of your text refers to electroMAGNETIC fields.  The two are different.  An electric field caused by a charge particle (or pair thereof) would fall under the topic of classical electroSTATICs, meaning what happens related to non-moving charged particles.  ElectroDYNAMICS refers to what happens once you start moving charges around and produce currents, thereby producing magnetic fields, etc.  Varying the dynamics (accelerating/decelerating particles) produces electromagnetic radiation where energy propagates away from the moving charges in the form of electromagnetic waves.  

Now, it terms of what makes a charged particle produce a field, you're getting into the field of quantum mechanics.  Talking about electric fields in terms of Maxwell's equations remains in the classical EM realm and cannot explain the "cause" of the field; only that there are such things as charged particles and that they exert a force on each other and that force can be quantified in terms of the amount of charge on each particle/object and their separation.  The concept of the electric field is simply a general way to remove one of the two charged objects and talk about the force on another charged object without any knowledge of the other charges around it.  Thus, the concept of a vector field that interacts with a charge and produces a force was introduced.  One can then evaluate what that means about the "source" of the field, but the concept does not REQUIRE that there be a source.  The fact that the sub-atomic particles of electrons and protons have a charge and "produce" electric fields is simply a given.  The REASON why they do so (and why it's quantized) cannot be explained from classic electrodynamics and is a topic of study for quantum mechanics, along with the other natural forces such as gravity (which we still don't understand).  Given that my background is firmly rooted in classical physics and I don't claim to have a good handle on quantum mechanics, that's as far as I can take you.  Your references are pointing to a quantum mechanical discussion, but that's not what I'm getting from your question and comments.

On a side note, regarding Maxwell's equations.  The fact that the magnetic force (and correspondingly the magnetic "field") only arises from a moving electric charge really disturbs some people.  The good news is that the classical Maxwell's equations don't actually preclude the existence of a magnetic monopole (a separate "north" or "south" pole without having to have the other) and should such a particle ever be discovered, the equations would be modified into a beautifully symmetrical definition where moving magnetic monopoles produce electric fields just like moving electric charges produce magnetic fields.  In the meantime it makes for some great science fiction!  (See Larry Niven's "Known Space" series.)  

Dear Michael

Thank you for interesting description. 

You have written: "You keep asking about electric fields, but all of your text refers to electromagnetic fields."

Consider to main question that is "How electromagnetic fields are generated?" So, this discussion is related to electromagnetic force that according to QM, electromagnetic force is carrying by virtual photon. A changing magnetic field makes an electric field. A changing electric field makes a magnetic field.

In totally, if we can describe how a charged particle does produce electric field, it leads us to explain how a charged particle produces virtual photon.

Dear Hossein, if you want to calculate electromagnetic field you should use quantum electrodynamics (QED), that is, D'alembert  equation and current. You may use photons for pleasant chats.

Dear Marat

This discussion is related to the mechanism of electromagnetic field generating, not its calculations, which can be achieved by combining electromagnetism and gravity.

dearest java

maybe this informatoin could help

Dear mohd arinal

These pictures belong to classical mechanics, but this discussion is related to quantum mechanics, in fact beyond the quantum mechanics.

Scattering of light by matter has been studied extensively in the past. Yet, the most fundamental process, the scattering of a single photon by a single atom, is largely unexplored. One prominent prediction of quantum optics is the deterministic absorption of a travelling photon by a single atom, provided the photon waveform matches spatially and temporally the time-reversed version of a spontaneously emitted photon. [1 and figures]

Here we experimentally address this prediction and investigate the influence of the photon’s temporal profile on the scattering dynamics using a single trapped atom and heralded single photons. We don't often think of photons as being spread out in time and space and thus having a shape, but the ones in this experiment were some four meters long. Christian Kurtsiefer, Principal Investigator at CQT, and his team have learned to shape these photons with extreme precision.

EM fields are a well researched type of dipole polarization of space. How it works is well understood. Why it happens in a vacuum is an open question that might eventually lead to new discoveries.

Dear Jerry

I agree with you on "Why it happens in a vacuum is an open question" and disagree on "that might eventually lead to new discoveries." Because I generalize the Maxwell equations of electromagnetism to the gravitational field. I have used the pair production and decay to show that a charged particle acts like a generator, the generator input and output are gravitons and virtual photon.

I draw you attention that photon itself existence is not mandatory for wave description.

Yes, it refers to duality.

The Standard Model describes the phenomena within its domain accurately, it is still incomplete. Perhaps it is only a part of a bigger picture of the modern physics which includes the deeper and hidden layer of subatomic world that has been dipped into the darkness of the universe.

http://home.cern/about/physics/standard-model

Hidden part of modern physics lies beyond the uncertainty principle. Included in the sub quantum scale, where quantum interactions between photons and gravitons done. Hidden and dark side of modern physics is also a place where charged particles absorb and emit energy quanta, without any description of the mechanism of absorption and emission by charged particles. In modern physics, a charged particle creates an electric field itself, but the mechanism of this process is ambiguous and does not explain how a charged particle creates an electric field?

To describe zero point energy we should consider that space is full of gravitons and graviton is a basic element to produce energy. There is no physical point in space devoid of gravity effect. Therefore, at any physical point in the space, there are energy production facilities. Under the terms of Sub Quantum energy scale, when intensity of gravitational field increases or interfere gravitational fields of two massive bodies that are moving adjacent each other, gravity produces the electromagnetic energy. But the amount of electromagnetic energy in space depends to density of gravitons in the space.

According to CPH Theory, we can describe the mechanisms of zero-point energy production without using uncertaintity principle. About the vacuum energy, the Maxwell's equations can be generalized in vacuum.

According to the quantum mechanics that photon and electron are unstructured particle, we cannot describe the mechanism of absorption and emission photon by electron that is logically unacceptable. As it was described photons are combination of positive and negative virtual photons. Photon is a very weak electric dipole that is consistent with the experience and this book is asserted.

See Sections 1 and 2 of:

Beyond the Standard Model : Modern physics problems and solutions

https://www.amazon.com/gp/offer-listing/1939123623

Honestly, modern physics cannot answer this question. The reason for the inability of modern physics to answer the question and many other questions is that in quantum mechanics, particles are point-like, unstructured and non-productive.

While in CPH Theory, charged particles have the structure that produces their own electric fields.

To find the answer let's review and analyze the pair production and decay electron-positrons in a different approach. For more detail see:
