The wave phase is the origin of creation and precedes the particulate (molecular) phase. The wave and particle are not two figures of the same thing, rather they are heterogeneous and different from each other due to the different sources of each of them. The particulate phase is just generated by impinging of the wave on its target of spatial forces (Higgs field), and the wave phase is considered the extra dimensions or the extended fuzzy end of the particle. Because electrons are forced to move in synchrony, they can produce heat and light. The light would be reflected from the electron forming many synchronized shadows for the same electron at different places that could be misinterpreted by both the instrumental detectors and the person analyzing the results of observations. Therefore, the electron cannot exist in different places, rather the shadows of the same electron give false observational results that produced the false analytic conclusion of “probability and randomness” and thus the term “superposition” is not scientifically consistent or coherent– The energy and momentum of electrons influence their motion through a material, which, in turn, determines its electrical and optical properties. – Using laser pulses, physicists have been able to generate hot electrons that travel faster than the speed of light. Regarding the electrons in the famous double-slit experiment, they are considered accelerated electrons, so their speed is faster than the speed of light. Because the light emitted from electrons and the light of the electron detector (ICCD camera) are electromagnetic waves, the speed of light emitted from electrons is faster than that of the detector. Consequently, the electron detector (ICCD camera) could detect the particle phase of electrons but couldn’t detect or capture the wave phase of electrons, because electromagnetic waves are harder to get a handle on. The result is the failure of observing and detecting the wave phase of electrons. Therefore, the wave function does not collapse.

“…These are in terms of its power [10][11][12][13][14], repetition rate [15], pulse width [16], operational frequency for short pulse lasers [17][18][19] etc. These developments have important consequences in many areas of applied and fundamental interest [20,21], such as fusion [22][23][24][25][26][27][28][29][30][31], particle acceleration [32][33][34][35][36][37][38], novel radiation sources [39][40][41][42][43][44], magnetic field generation and transport [45][46][47][48][49][50][51].

Parametric processes play an important role in applications related to laser plasma interaction [P. K. Kaw, Review of Modern Plasma Physics, 1.1 (2017)]. Occurrence of these processes has primarily been reported in the context of laser interacting with an un-magnetized plasma. The regime of magnetized plasma, on the other hand, has remained largely unexplored from this perspective. Recent technological advancements in the production of high magnetic fields [Nakamura, Daisuke, et al., Review of Scientific Instruments, 89.9, 095106 (2018)] bring the area of laser interaction with magnetized plasma targets to the forefront of investigation. In this study, the parametric process of Brillouin scattering for a magnetised plasma target has been demonstrated with the help of one dimensional Particle-in-cell simulations using the platform of OSIRIS-4.0. The external magnetic field has been chosen to be directed along the laser propagation direction. This geometry supports the propagation of right (R) and left (L) circularly polarized electromagnetic waves in the plasma when the laser frequency falls in the appropriate pass band of the respective dispersion curves. A detailed study identifying the scattering process with differing strengths of the applied external magnetic field, and for various polarizations of the incident electromagnetic pulse has been carried out. The conditions favouring the excitation of parametric Brillouin scattering process has been outlined. The nonlinear regime of the scattering process has also been investigated.

“…Intense short-pulse lasers interacting with solid targets can accelerate target electrons and produce high-currentdensity (∼10 12 A cm −2 ) relativistic electron beams (REBs) of micrometer-scale radius [25][26][27][28][29][30][31][32][33][34][35][36]. Motivated by the FI scheme [37][38][39][40] and TNSA of ions to high energies [41], the transport of REBs in dense plasma is gaining much research attention, and interesting phenomena have been discovered, including spontaneous magnetic field generation, heating of plasmas, self-channeling of REBs, as well as their filamentation and coalescence [38][39][40][41][42][43][44].…”

Transport of moderate relativistic micro electron beam in overdense plasma is investigated using numerical simulation and analytical modeling. It is found that if the product of the initial beam current density j b and radius R 0 is above a lower limit, which scales like, where n e is the plasma density, the beam will periodically self pinch and relax as it propagates. Otherwise the beam diverges. But if j R b 0 is too large, the pinching behavior becomes quite different. Such micro-beam transport behavior can be attributed to the nonlinear dynamics of the beam electrons in overdense plasma.
