“…Then the energy of one photon of this kind would be sufficient to ensure that there was a breakdown of the energy gap, generating an electron-positron pair. In this speculative limiting case acts the onephoton mechanism [8]! Figure 4 (left) illustrates the effect of such a sort of vacuum photoelectric effect, the photon knocks an electron-positron pair off the PV.…”

Abstract. The theoretical and experimental investigation of physical processes in strong fields of different nature (electromagnetic, gravitational, etc.) is one of the important directions of modern physics. Particular interest is devoted to the area of extremely strong fields, in which qualitatively new effects become important due to the restructuring of the physical vacuum which accompanies the creation of matter from the vacuum at modern laser facilities. Such kind of time-dependent strong field vacuum effects can be appropriately described within a kinetic theory approach as an effective instrument of theoretical investigations. A short review of recent achievements in the direction of the dynamical Schwinger effect is given in this contribution.

“…In addition to the above mentioned quasiclassical radiation, a quantum component of the radiation also exists due to elementary acts of interaction of the carriers with photons. In graphene, these mechanisms can be taken into account by analogy with the standard D = 3 + 1 QED [57,58,66]. Outside of the KE approach, this radiation mechanism was studied in Ref.…”

Radiation Problems Accompanying Carrier Production by an Electric Field in the Graphene

A number of physical processes that occur in a flat one-dimensional graphene structure under the action of strong time-dependent electric fields are considered. It is assumed that the Dirac model can be applied to the graphene as a subsystem of the general system under consideration, which includes an interaction with quantized electromagnetic field. The Dirac model itself in the external electromagnetic field (in particular, the behavior of charged carriers) is treated nonperturbatively with respect to this field within the framework of strong-field QED with unstable vacuum. This treatment is combined with a kinetic description of the radiation of photons from the electron-hole plasma created from the vacuum under the action of the electric field. An interaction with quantized electromagnetic field is described perturbatively. A significant development of the kinetic equation formalism is presented. A number of specific results are derived in the course of analytical and numerical study of the equations. We believe that some of predicted effects and properties of considered processes may be verified experimentally. Among these effects, it should be noted a characteristic spectral composition anisotropy of the quantum radiation and a possible presence of even harmonics of the external field in the latter radiation.

“…This is true at least when the gauge field is external: going beyond this is notoriously hard within the DHW approach [13], while perturbation theory is obviously straightforward in field theory. In order to ensure that the obtained solution is physical, one must use sensible initial data which corresponds to calculating the DHW function in a physical state.…”

We give an exact, analytic, and manifestly gauge invariant account of pair production in combined longitudinal and transverse electromagnetic fields, both depending arbitrarily on lightfront time. The instantaneous, nonperturbative probability of pair creation is given explicitly along with the spectra of the final particle yield. Our results are relevant to high-intensity QED experiments now being planned for future optical and x-ray free electron lasers.
