“…14 of Ref. [44], where the standard G(χ e ) is plotted, suggests that the quantum corrected result significantly reduces the classical estimate for χ e := −(F µν p ν ) 2 /(mE cr ) = Ep ⊥ /mE cr ∼ 0.5 − 1.…”

Strong field physics close to or above the Schwinger limit are typically studied with vacuum as initial condition, or by considering test particle dynamics. However, with a plasma present initially, quantum relativistic mechanisms such as Schwinger pair-creation are complemented by classical plasma nonlinearities. In this work we use the Dirac-Heisenberg-Wigner formalism to study the interplay between classical and quantum mechanical mechanisms for ultra-strong electric fields. In particular, the effects of initial density and temperature on the plasma oscillation dynamics are determined.

“…In the 20th century, Maxwell's equations had an impact beyond electromagnetism in the discovery of the theory of relativity and the field equations of quantum mechanics, which is the profound and the most fruitful in experimental physics since the time of Newton The Link Between the Spread Information and the Maxwell's Equation 07of electrical and electronic equipment. The reason why these equations can be solved only for structures of high symmetry [17,18].…”

The Forces between two charges are one the four fundamental forces that keep the world together Indeed when a single photon is emitted, it spreads over a system, the intensity decrease by square law of the distance which compliant with conservation of energy. A changing magnetic field creates an electric field, and a changing electric field creates a magnetic field, and an accelerating electric field creates an accelerating magnetic field. Electric lines are modeled for visualizing the effect in space of electrostatic forces that occur two or more charged particles. Maxwell equation provides a Mathematical model for electric, optical and radio technologies such as power generation, electrical motor and wireless communication. Unfortunately, Maxwell's equation requires some advanced techniques which lie well beyond the understanding of this paper. The derivation of maxwell's equations is approach established for the time -dependent from static laws, The variation of electrical fields and magnetic field and Faraday's law can be derived without any assumption relativistic.

“…The energy requirements to confine the electron beam are much less for a FF pulse because the peak intensity moves with the electron beam, which decouples the interaction length from the Rayleigh range. Confinement of the charged particles is aided by radiative cooling (radiation reaction [23][24][25][26]), which decreases the emittance and mean-squared radius of the beam at the cost of its average energy.…”

We demonstrate the capability of Flying Focus (FF) laser pulses with = 1 orbital angular momentum (OAM) to transversely confine ultra-relativistic charged particle bunches over macroscopic distances while maintaining a tight bunch radius. A FF pulse with = 1 OAM creates a radial ponderomotive barrier that constrains the transverse motion of particles and travels with the bunch over extended distances. As compared to freely propagating bunches, which quickly diverge due to their initial momentum spread, the particles co-traveling with the ponderomotive barrier slowly oscillate around the laser pulse axis within the spot size of the pulse. This can be achieved at FF pulse energies that are orders of magnitude lower than required by Gaussian or Bessel pulses with OAM. The ponderomotive trapping is further enhanced by radiative cooling of the bunch resulting from rapid oscillations of the charged particles in the laser field. This cooling decreases the mean square radius and emittance of the bunch during propagation.
