“…In the same figure, one can also observe packets of electrons heated symmetrically in both positive and negative p y directions. To interpret this result, one can notice that the phase space, although more diffuse in our case, is very similar to what has been already observed 30,31 at higher laser intensities and denser plasmas due to the self-generation of large quasistatic magnetic fields [32][33][34] at the plasma surface. In our case, the magnetic field component at the surface is dominated by the resonant oscillating magnetic field of the surface wave.…”

International audienceTwo-dimensional (2D) particle-in-cell numerical simulations of the interaction between a high-intensity short-pulse p-polarized laser beam and an overdense plasma are presented. It is shown that, under appropriate physical conditions, a surface plasma wave can be resonantly excited by a short-pulse laser wave, leading to strong relativistic electron acceleration together with a dramatic increase, up to 70%, of light absorption by the plasma. Purely 2D effects contribute to enhancement of electron acceleration. It is also found that the angular distribution of the hot electrons is drastically affected by the surface wave. The subsequent ion dynamics is shown to be significantly modified by the surface plasma wave excitation

“…In this case all three-waves processes are absent. This means in pair plasma the coupling of transverse plasmons will not excite low-frequency magnetization currents, this result is consistent with that in [25,26] if they are extended to pair plasmas. (5) In this paper we focus on investigating the behavior of transverse plasmons in pair plasmas without ambient magnetic field by a kinetic method.…”

A set of nonlinear governing equations for interactions of transverse plasmons with pair plasmas is derived from Vlasov-Maxwell equations. It is shown the ponderomotive force induced by high-frequency transverse plasmons will expel the pair particles away, resulting in the formation of density cavity in which transverse plasmons are trapped. Numerical results show the envelope of wave fields will collapse and break into a filamentary structure due to the spatially inhomogeneous growth rate. The results obtained would be useful for understanding the nonlinear propagation behavior of intense electromagnetic waves in pair plasmas.
