An interferometer in which all of its components are treated as quantum bodies is examined with the standard interpretation and with a model in which its uncoupled spatially separated components act collectively. These models utilize superposition principles that differ when applied to systems composed of three or more bodies. Interferometric disparities between them involving frequency shifts and recoil are shown to be difficult to measure. More pronounced discrepancies involve correlated interference. The collective model is shown to provide a missing connection between quantum and semiclassical theories. Scattering from an entangled state, which cannot be divided into disjoint parts, is discussed in relation to collective recoil. Collective scattering is shown to be a viable alternative to the standard model, thereby providing insight into constructing tests of the superposition principle in systems with three or more bodies.

“…( 51) and ( 53) well describe the field distribution and its propagation of the RLF, its limitation should be addressed here. In this study, an ideal RFPM, which has a constant velocity and a flat perfect reflectance over the wavelength and incidence angle, is assumed and the recoil effect happening during the reflection of the incident strong laser pulse [57] is ignored. Therefore, obtaining a mathematical expression for the RLF under a more realistic circumstance will be the next step to be pursued.…”

The question of electromagnetic field intensification towards the values typical for strong field Quantum Electrodynamics is of fundamental importance. One of the most promising intensification schemes is based on the relativistic-flying mirror concept, which shows that the electromagnetic radiation reflected by the mirror will be frequency up-shifted by a factor of 4γ 2 (γ is the Lorentz factor of the mirror). In laser-plasma interactions, such a mirror travels with relativistic velocities through plasma and typically has a parabolic form, which is advantageous for light intensification. Thus, a relativistic-flying parabolic mirror reflects the counter-propagating radiation in a form of focused and flying electromagnetic wave with a high frequency. The relativistic-flying motion of the laser focus makes the electric and magnetic field distributions of the focus complicated, and the mathematical expressions describing the field distributions of the focus become of fundamental interest. We present analytical expressions describing the field distribution formed by an ideal flying mirror which has a perfect reflectance over the entire surface and wavelength range. The peak field strength of an incident laser pulse with a center wavelength of λ0 and an effective beam radius of we is enhanced by a factor proportional to γ 3 (we/λ0) in the relativistic limit. Electron-positron pair production is investigated in the context of invariant fields based on the enhanced electromagnetic field. The pair production rate under the relativistic-flying laser focus is modified by the Lorentz γ-factor and the beam radius-wavelength ratio (we/λ0). We show that the electron-positron pairs can be created by colliding two counter-propagating relativistic-flying laser focuses in vacuum, each of which is formed when a 180 TW laser pulse is reflected by a relativistic-flying parabolic mirror with a γ = 12.2.

“…The RFM is a high-density electron layer and a part of the plasma cavity formed behind a propagating laser pulse. The physical properties of a laser pulse reflected by the RFM can be found in recent publications [2][3][4][5][6][7]. The RFM formed in the plasma cavity can be understood as a relativistic-flying parabolic mirror (RFPM) due to its paraboloidal shape.…”

The reflection of a laser pulse by a relativistic-moving mirror is one of fundamental problems encountered in the highpower laser and plasma interactions. It is well known that a laser pulse reflected by a relativistic-flying mirror experiences the intensification of its intensity, frequency up-shift, and shortening of pulse duration. Thus, it is of fundamental interest to have a mathematical solution expressing the intensity distribution of a laser pulse reflected by a relativistic-flying parabolic mirror. In this paper, we present analytical and mathematical formulae describing the electromagnetic field of a laser pulse reflected and focused by the relativistic-flying parabolic mirror.
