Summary: The coupling between PIC and MC algorithms can lead to numerical heating that significantly affects the evolution of the simulated system, especially for long simulation times. This heating arises from an inconsistency between particle motion in MC collisions and the work done by the electromagnetic field on the PIC grid.

Summary: In this paper, a novel 2D reduced numerical model for stimulated Raman scattering (SRS) in laser fusion plasmas is presented. It couples envelope equations for electromagnetic fields with a hybrid description of the electron species. The model accurately reproduces linear Landau damping and trapped-particle instabilities, and shows good agreement with experimental data.

Summary: This article considers a new type of kinetic models with non-instantaneous binary collisions. Collisions are described by a transport process in the joint state space of a pair of particles. The interactions belong to the alignment type, where the states of the particles approach each other. For two spatially homogeneous models with deterministic or stochastic collision times, the existence and uniqueness of solutions, the long-time behavior, and the instantaneous limit are considered, with the latter leading to standard kinetic models of Boltzmann type.

Summary: A study on magnetized plasma reveals the redistribution of charged particles in momentum due to Coulomb collisions. The leading-order approximation of this scenario is consistent with the generalizations of the Lenard-Balescu equation that include magnetic field effects, and a correction for the time variations of plasma parameters is developed.

Summary: A novel drag-diffusion Langevin method for hybrid kinetic-fluid Coulomb scattering in plasmas is proposed in this study. The method applies frictional drag in the simulation frame of reference and performs velocity-space diffusion in either the stationary-fluid frame or the laboratory frame depending on the anisotropy. First-order modifications to the electron velocity distribution function are investigated for accurate calculation of electric resistivity. The results show that the Langevin method allows for larger timesteps without numerical failure when compared to a grid-based binary method.

Summary: This study used Raman spectroscopy and stimulated Raman scattering (SRS) to investigate the hydrogen bonding (HB) network in 1,2-propanediol-water binary solutions. Abnormal changes in HBs were detected at a volume fraction of 1,2-propanediol of 0.4, with the HB strength of water weakened and then strengthened. SRS also revealed the appearance of ice-like structures near the methyl group and a weakening of HBs. These findings provide valuable insights into the HB networks in alcohol-water binary solutions.

Summary: The kinetic stimulated Raman scattering (SRS) can generate significant Weibel magnetic fields that can be an important source in laser-plasma experiments. The application of a transverse magnetic field can change the motion of hot electrons and destroy the symmetry of SRS and Weibel-generated magnetic fields.

Summary: The reduction of the two-time formalism to a scenario of plasma particle redistribution in momentum due to Coulomb collisions is discussed, focusing on an ideal classical ionized homogeneous plasma. It is shown that the leading-order approximation of this scenario agrees with the well-known Lenard-Balescu equation. A correction to the collision integral of this equation is developed to account for the time variation of plasma parameters, which differs from the existing generalizations of the Lenard-Balescu kinetic equation.

Summary: This paper investigates the influence of Coulomb damping on the wave propagation behavior of cubically nonlinear monoatomic phononic chains. The nonlinear dispersion relation is obtained analytically using the multiple scales method and the band structure of the damped nonlinear chains is compared to the linear and nonlinear undamped chains. Coulomb damping can lead to lower dispersion frequencies in the chain due to the coupling between the amplitude and the frequency, resulting from the nonlinear nature of the chain. This study captures the effect of Coulomb damping on the wave propagation behavior of nonlinear lattices, bringing us closer to developing a comprehensive analytical model for the behavior of damped phononic crystals.

Summary: Dynamic light scattering (DLS) is a method for analyzing colloidal systems based on refractive index fluctuations. This paper demonstrates the theoretical feasibility of nonlinear dynamic light scattering (NLDLS) using stimulated Raman effect to reflect molecular vibration. By interfering with two pump beams, the spatial Fourier component of the imaginary part of the third-order nonlinear susceptibility can be extracted, providing mesostructural sensitivity with molecular vibration selectivity.

Summary: This paper proposes a theoretical scheme for synthesizing a white laser source based on the cascaded sum frequency generation (CSFG) model and stimulated Raman adiabatic passage (STIRAP). The results show that by adjusting the pump parameters and coupling delay parameters, stable RGB laser output can be achieved. The new scheme offers better stability compared to the scheme based on frequency conversion with Stark-chirped rapid adiabatic passage for synthesizing a white laser source.
