“…Alpha-particle stopping in dense ionized matter is essential to achieve ignition in inertial confinement fusion 1 – 5 . Fast ignition (FI) relies even more on a detailed understanding of ultrahigh-current ion stopping in matter, which is therefore considered as a fundamental process of utmost importance to nuclear fusion.…”

Intense particle beams generated from the interaction of ultrahigh intensity lasers with sample foils provide options in radiography, high-yield neutron sources, high-energy-density-matter generation, and ion fast ignition. An accurate understanding of beam transportation behavior in dense matter is crucial for all these applications. Here we report the experimental evidence on one order of magnitude enhancement of intense laser-accelerated proton beam stopping in dense ionized matter, in comparison with the current-widely used models describing individual ion stopping in matter. Supported by particle-in-cell (PIC) simulations, we attribute the enhancement to the strong decelerating electric field approaching 1 GV/m that can be created by the beam-driven return current. This collective effect plays the dominant role in the stopping of laser-accelerated intense proton beams in dense ionized matter. This finding is essential for the optimum design of ion driven fast ignition and inertial confinement fusion.

“…The past few years have seen two important advances. One was the proposal of initiating fusion reactions [2] for viable energy production that would quench humanity's endless thirst for energy without worsening the global climate change. Another noteworthy advance was the laser-driven particle accelerators [3].…”

This paper presents an investigation on nonlinear propagation of quadruple Gaussian (Q.G) laser beam in narrowband semiconductor (e.g., n-type InSb) plasmas. In the presence of laser beam, the electron fluid in the conduction band becomes relativistic that makes the medium highly nonlinear. As a result the laser beam gets self-focused. Following variational theory approach in W.K.B approximation the numerical solution of the nonlinear Schrodinger wave equation (NSWE) for the field of incident laser beam has been obtained. Particular emphasis is put on dynamical variations of beam spot size and longitudinal phase (Gouy phase). Self-trapping of the laser beam resulting from the dynamical balance between diffraction broadening and nonlinear refraction also has been investigated.

“…When the amplitude is equal to the wavelength, the disturbance begins to become asymmetric, and then grows nonlinearly, and finally enters the turbulent mixing stage [1]. The RT instability is a typical and fundamental interfacial instability that plays an important role in many fields, such as inertial confinement fusion [2,3,4], supernova explosions [5,6,7], meteorology [8,9], and geophysics [10,11,12]. Therefore, the study of RT instability has important theoretical significance and application value, and has aroused considerable interest and been developed rapidly.…”

Rayleigh-Taylor (RT) instability widely exists in nature and engineering fields.How to better understand the physical mechanism of RT instability is of great theoretical significance and practical value. At present, abundant results of RT instability have been obtained by traditional macroscopic methods. However, research on the thermodynamic non-equilibrium (TNE) effects in the process of system evolution is relatively scarce. In this paper, the discrete Boltzmann method based on non-equilibrium statistical physics is utilized to study the ef-
