Author(s): A. Di Siena, A. Bañón Navarro, and F. Jenko Turbulent transport is known to limit the plasma confinement of present-day optimized stellarators. To address this issue, a novel method to strongly suppress turbulence in such devices is proposed, namely the resonant wave-particle interaction of suprathermal particles—e.g., from ion-cyclotron-reso...

Author(s): Y. Wan, I. A. Andriyash, W. Lu, W. B. Mori, and V. Malka Acceleration of ultrathin foils by the laser radiation pressure promises a compact alternative to the conventional ion sources. Among the challenges on the way to practical realization, one fundamental is a strong transverse plasma instability, which develops density perturbations and breaks the acc... [Phys. Rev.

Author(s): Shuai Zhang and S. X. Hu Shock release from inertial confinement fusion (ICF) shells poses a great challenge to single-fluid hydrodynamic equations, especially for describing materials composed of different ion species. This has been evidenced by a recent experiment [Haberberger et al., Phys. Rev. Lett. 123, 235001 (2019) ],... [Phys. Rev. Lett. 125, 105001] Published Mon Aug 31,...

Author(s): Tobias Dornheim, Jan Vorberger, and Michael Bonitz Warm dense matter (WDM)—an extreme state with high temperatures and densities that occurs, e.g., in astrophysical objects—constitutes one of the most active fields in plasma physics and materials science. These conditions can be realized in the lab by shock compression or laser excitation, and the m... [Phys. Rev. Lett. 125, 085001] Published Wed Aug 19, 2020

Campbell A new class of ignition designs is proposed for inertial confinement fusion experiments. These designs are based on the hot-spot ignition approach, but instead of a conventional target that is comprised of a spherical shell with a thin frozen deuterium-tritium (DT) layer, a liquid DT...
