Pulse interaction in nonlinear vacuum electrodynamics
نویسنده
چکیده
The energy-momentum conservation law is used to investigate the interaction of pulses in the framework of nonlinear electrodynamics with Lorentz-invariant constitutive relations. It is shown that for the pulses of the arbitrary shape the interaction results in phase shift only.

The Intense Radiation Gas
– We present a new dispersion relation for photons that are nonlinearly interacting with a radiation gas of arbitrary intensity due to photon–photon scattering. It is found that the photon phase velocity decreases with increasing radiation intensity, it and attains a minimum value in the limit of super-intense fields. By using Hamilton's ray equations, a self-consistent kinetic theory for inter...
متن کاملField-gradient-induced second-harmonic generation in magnetized vacuum
The photon-photon scattering in vacuum can give rise to the second-harmonic generation of intense laser radiation in a dc magnetic field in the ‘‘box’’ diagram approximation of quantum electrodynamics if the symmetry of interaction is broken by modulation or/and nonuniformity of optical wave 1dc field system in time or/and space. Specific examples considered here are: an optical pulse plane wav...
متن کاملNonlinear collective effects in photon–photon and photon–plasma interactions
We consider strong-field effects in laboratory and astrophysical plasmas and high intensity laser and cavity systems, related to quantum electrodynamical (QED) photon–photon scattering. Current state-of-the-art laser facilities are close to reaching energy scales at which laboratory astrophysics will become possible. In such high energy density laboratory astrophysical systems, quantum electrod...
متن کاملInterferometry of light propagation in pulsed fields
– We investigate the use of ground-based gravitational-wave interferometers for studies of the strong-field domain of QED. Interferometric measurements of phase velocity shifts induced by quantum fluctuations in magnetic fields can become a sensitive probe for nonlinear self-interactions among macroscopic electromagnetic fields. We identify pulsed magnets as a suitable strong-field source, sinc...

A new process associated with the nonlinear optical properties of the electromagnetic vacuum, as predicted by quantum electrodynamics, is described. This can be called photon acceleration in vacuum, and corresponds to the frequency shift that takes place when a given test photon interacts with an intense beam of background radiation.
