What kind of energy is needed to create new particle pair or Atom?

[Dandav]

Based on Einstein formula  

E = MC^2

There are different kinds of energies.

However, only one kind of energy appears independently.

This energy is Electromagnetic energy:

Electromagnetic energy (light, radio waves, microwave, infrared, ultraviolet, ...) = radiation energy. It is energy advancing in the form of an electromagnetic wave in space (including vacuum), at the speed of light. It is the only energy that appears independently, without the need for the presence of matter.

Therefore, could it be that electromagnetic energy is the only energy in the Universe that can create new particle pair / Atom / molecules?

In other words, if we wish to create any kind of new matter, electromagnetic energy is needed.

In the following article it is stated:

"Pair creation in a uniform classical electromagnetic field (Schwinger mechanism) is studied focusing on the time evolution of the distribution of created particles. 

Heisenberg and Euler found that the 1-loop effective action of QED in a classical electric field has an imaginary part, which means a vacuum in an electric field is unstable against creation of particle–antiparticle pairs. In 1951, Schwinger fully formalized it using the proper time method [5], and thus particle creation in a classical electric field is called Schwinger mechanism. 

For e+e- pair creation, an electric field strength of the order or above the critical value Ec=m2/e∼10^16 V/cm is needed, which is beyond current technological capabilities."

Hence, Electromagnetic field strength above this critical value has the ability for the particle–antiparticle pairs creation in a vacuum.

This is another indication that the energy that is locked in any particle / boson in the nature must be EM energy.

In the same token, in a fission / fusion activity we convert the particle mass into energy:

"Fission occurs when a neutron strikes the nucleus of either isotope, splitting the nucleus into fragments and releasing a tremendous amount of energy."

That tremendous amount of energy must also be EM energy and it appears independently.
