“…According to the calculations in Kornev et al, 2009, inelastic and collective tunneling effects contribute significantly to the relativistic ionization dynamics at intensities larger than 10 18 W/cm 2 , thus changing the ionization probability by more than one order of magnitude (see Fig. 4).…”

“…Adapted from Kornev et al, 2009. but were concealed by competing rescattering effects. In Kornev et al, 2009, it was shown that, in the relativistic regime, the role of inelastic and collective tunneling can significantly increase and the relativistic PPT rate has been generalized in this respect. In a linearly polarized field, the rate R (N ) coll of inelastic collective tunneling of N equivalent electrons from the outer shell of an ion is described by the following universal formula (Kornev et al, 2009):…”

The field of laser-matter interaction traditionally deals with the response of atoms, molecules and plasmas to an external light wave. However, the recent sustained technological progress is opening up the possibility of employing intense laser radiation to trigger or substantially influence physical processes beyond atomic-physics energy scales. Available optical laser intensities exceeding 10 22 W/cm 2 can push the fundamental lightelectron interaction to the extreme limit where radiation-reaction effects dominate the electron dynamics, can shed light on the structure of the quantum vacuum, and can trigger the creation of particles like electrons, muons and pions and their corresponding antiparticles. Also, novel sources of intense coherent high-energy photons and laserbased particle colliders can pave the way to nuclear quantum optics and may even allow for potential discovery of new particles beyond the Standard Model. These are the main topics of the present article, which is devoted to a review of recent investigations on high-energy processes within the realm of relativistic quantum dynamics, quantum electrodynamics, nuclear and particle physics, occurring in extremely intense laser fields.

“…We have developed the many-body theory of tunnel ionization earlier in Refs. [21][22][23][24][25][26]. Within the framework of this theory, it has been shown that for the ions of multiplicity 2 and higher the inelastic tunnel effect (ITE) appears to be quite essential, allowing to take into account the filling of the ion excited states within the intermediate stages of the process [23,24].…”

We report the numerical calculation of Ar 9+ · · · Ar 13+ , Kr 13+ · · · Kr 17+ , and Xe 19+ · · · Xe 23+ ion yield in the laser field with intensity exceeding 10 19 W/cm 2 . The results of the calculations agree with the experimental data [K. Yamakawa et al., Phys. Rev. A 68, 065403 (2003)] (for the Ar ions) or qualitatively (for the Kr ions). The theoretical results disagree with the experimental data for the Xe ions. We discuss the possible influence of the relativistic effects on this disagreement between theory and experiment. We obtained the approximation formula for the position of the maximum ionic population with the given ionization multiplicity Z depending on the radiation intensity. This position is described by the power function of Z; the exponent is determined by the dependence of sequential ionization potentials on Z value. We discuss the dependence of the approximation formula parameters on the value of the FWHM of the laser pulse.
