“…Analysing this realm of processes, Syrovatskii [75] first proposed the dynamic dissipation of the magnetic field. Theoretical and numerical works demonstrated the intensive charged particles acceleration in the MR current sheet driven by inductive electric field and proved the important role of displacement current in such an ultra-relativistic process [76,77] . Recent kinetic simulation in a 3D geometry presented the electron ejection from the non-adiabatic region in MR, the formation and evolution of the current sheet with the growth of tearing-like mode instability [78] .…”

Magnetic reconnection driven by laser plasma interactions attracts great interests in the recent decades. Motivated by the rapid development of the laser technology, the ultra strong magnetic field generated by the laser-plasma accelerated electrons provides unique environment to investigate the relativistic magnetic field annihilation and reconnection. It opens a new way for understanding relativistic regimes of fast magnetic field dissipation particularly in space plasmas, where the large scale magnetic field energy is converted to the energy of the nonthermal charged particles. Here we review the recent results in relativistic magnetic reconnection based on the laser and collisionless plasma interactions. The basic mechanism and the theoretical model are discussed. Several proposed experimental setups for relativistic reconnection research are presented.

“…Although the number of the positrons and the creation efficiency is not very high, the positron beam obtained in our mechanism is ultra-short and has ultra-relativistic energy. Several mechanisms have been proposed recently for positron creation and acceleration [30][31][32][33][34]. The positron bunches created in this paper can be used as an ideal external injection source for further acceleration.…”

A mechanism of high energy and high density positron beam creation is proposed in ultra-relativistic laser-plasma interaction. Longitudinal electron self-injection into a strong laser field occurs in order to maintain the balance between the ponderomotive potential and the electrostatic potential. The injected electrons are trapped and form a regular layer structure. The radiation reaction and photon emission provide an additional force to confine the electrons in the laser pulse. The threshold density to initiate the longitudinal electron self-injection is obtained from analytical model and agrees with the kinetic simulations. The injected electrons generate γ-photons which counter-propagate into the laser pulse. Via the Breit-Wheeler process, well collimated positron bunches in the GeV range are generated of the order of the critical plasma density and the total charge is about nano-Coulomb. The above mechanisms are demonstrated by particle-in-cell simulations and single electron dynamics. Simulation setupThe simulations are performed with the relativistic electromagnetic code EPOCH [18,19] in two and three spatial dimensions.

“…In our recent research using 2D Particle-in-cell (PIC) simulations, we have found that fast relativistic magnetic annihilation is achieved with two parallel ultra-short petawatt laser pulses co-propagating in an underdense plasma (see Fig. 22 (a)) [44,45]. The two magnetic dipoles generated by the laser pulses annihilate in the current sheet formed at the central axis.…”

ELI-Beamlines (ELI-BL), one of the three pillars of the Extreme Light Infrastructure endeavour, will be in a unique position to perform research in high-energy-density-physics (HEDP), plasma physics and ultra-high intensity (UHI) (1022W/cm2) laser–plasma interaction. Recently the need for HED laboratory physics was identified and the P3 (plasma physics platform) installation under construction in ELI-BL will be an answer. The ELI-BL 10 PW laser makes possible fundamental research topics from high-field physics to new extreme states of matter such as radiation-dominated ones, high-pressure quantum ones, warm dense matter (WDM) and ultra-relativistic plasmas. HEDP is of fundamental importance for research in the field of laboratory astrophysics and inertial confinement fusion (ICF). Reaching such extreme states of matter now and in the future will depend on the use of plasma optics for amplifying and focusing laser pulses. This article will present the relevant technological infrastructure being built in ELI-BL for HEDP and UHI, and gives a brief overview of some research under way in the field of UHI, laboratory astrophysics, ICF, WDM, and plasma optics.
