Summary: By using attosecond transient reflection spectroscopy, researchers investigated light-driven excitation in monocrystalline germanium and found that complex light-matter interactions require detailed analysis in time and reciprocal space. The results suggest that field-driven phenomena during charge injection may hinder the process, highlighting the importance of understanding the diverse physical mechanisms behind light-matter interaction to achieve petahertz information technology.

Summary: This study demonstrates the use of traveling evanescent terahertz waves to control subrelativistic electron pulses with high velocity matching and acceleration gradients. By controlling the selected terahertz delays and phases, attosecond streaking, temporal pulse compression, acceleration, and spatial focusing of electron pulses are achieved.

Summary: This study demonstrates control of plasmonic excitations in prototype models of topological insulators by molecule-scale perturbations using a fully quantum mechanical approach. The impact of added molecules on locally confined collective excitations is evaluated numerically, revealing shifts in plasmonic energies and changes in spatial charge density profiles. Significant charge transfer conditions and induced field energy density due to external electric fields in perturbed topological systems are identified.

Summary: Field emission of electrons is essential for advancements in science and technology, allowing for higher frequency signal processing and atomic-scale imaging. The use of intense laser pulses has enabled confinement and control of optical field emission, but the measurement of attosecond electron pulses has been challenging. In this study, intense sub-cycle light transients were used to induce and investigate the dynamics of electron pulses, providing new opportunities for research in attosecond physics and nano-optics.

Summary: Attosecond science utilizes the extreme nonlinearity of few-cycle pulses to achieve attosecond temporal resolution for real-time observation of electron motion in matter. Recent research reveals the rapid electronic response in dielectric systems triggered by few-cycle pulses, enabling ultrafast data processing and information encoding at speeds exceeding one petabit per second.

Summary: This article discusses the dynamical phase transition in Vicsek systems and investigates their chaotic behavior by computing the largest Lyapunov exponent (LLE). The authors find a chaotic regime for the collective behavior of the self-propelled particles (SPPs) based on the LLE and observe a significant change in the dependence of LLE on applied noise near the known transition points of the Vicsek model.

Summary: Vibrational wave packet dynamics of H-2(+) ions formed by ionization of neutral H-2 by attosecond extreme ultraviolet laser pulses are studied, with time-delayed dissociation of the cation by an ultraviolet probe pulse. Experimentally observable two-level quantum beats can be related to ion + photoelectron entanglement resulting from the ionization process, as supported by an evaluation of the purity of the reduced ion and photoelectron density matrices.

Summary: The study reveals that in active systems with topological interactions, spatial heterogeneities can maintain long-range order and enhance the emergence of traveling bands. Topological flocking models in heterogeneous environments exhibit features similar to metric models, with spatial heterogeneities inducing an effective density-order coupling that facilitates the emergence of traveling bands.

Summary: This study focuses on charge migration during light-matter interaction and proposes a scheme based on infrared pump and short extreme ultraviolet probe technique. By numerically solving the time-dependent Schrodinger equation combined with a simple double-slit model, laser-controlled charge migration can be directly reconstructed from interference patterns of the photoelectron spectrum.

Summary: The process of charge migration in molecules during photoionization can be induced and enhanced by placing the molecule in an optical cavity, which can be monitored using time-resolved photoelectron spectroscopy. It is found that the charge migration process in a cavity is local and does not exhibit collective effects.

Summary: The softening of interaction of active particles destabilizes the highly ordered dense phase, resulting in the formation of a porous cluster spanning the system. The system also exhibits standard percolation transition characteristics when the particle motility exceeds a critical value. Additionally, similar transitions are observed in the athermal limit, even at low motility. The phase diagram of repulsive active particles is revealed to be richer than previously conceived.

Summary: Through particle-in-cell simulations, giant isolated attosecond pulses can be directly generated from relativistic laser-driven plasmas, offering a promising alternative for ultrafast studies with high intensity without the need for further spectral filtering. The underlying radiation mechanism is coherent synchrotron emission, allowing the transmitted pulses to reach relativistic intensity.

Summary: This translation presents the results of the first commissioning phase of the short-focal-length area of the Apollon laser facility in France. The testing was conducted with the first available laser beam, with various diagnostics in place to assess the performance of the facility. The results showed good laser-to-target coupling efficiency and an overall performance comparable to similar international facilities, paving the way for further commissioning at a higher power level in 2022.
