Amplification of Laguerre-Gaussian laser pulses in plasma by copropagating Gaussian pulses

Fri, 06/20/2025 - 10:00

Author(s): Guoqing Yang, Min Chen, Xiaobo Zhang, Huanyu Song, Suming Weng, Ping Li, Tongpu Yu, and Zhengming Sheng

Laguerre-Gaussian (LG) laser beams have many interesting applications due to their unique field structure. However, the generation of intense LG beams remains challenging because of the limited damage threshold of intensity for optical elements used for the conversion from normal Gaussian beams to L…

Author(s): Amir Jafari

We employ well-known concepts from statistical physics, quantum field theories, and general topology to study magnetic reconnection and topology change and their connection in incompressible flows in the context of an effective field theory without appealing to magnetic field lines. We consider the …

Eigenvalues and eigenfunctions of Landau damping oscillations in very weakly collisional plasma

Fri, 06/20/2025 - 10:00

Author(s): Evgeny V. Polyachenko and Ilia G. Shukhman

Landau-damped oscillations in collisionless plasmas, described by van Kampen and Case, are quasimodes, representing a continuous superposition of singular eigenfunctions, not true eigenmodes. Recent work by Ng et al. shows that even rare collisions replace these singular modes with discrete regular …

Inertial confinement of fusion plasmas can be realized using the dynamic Z pinch, an electromagnetically driven cylindrical implosion system that is also used to generate intense x rays. However, the Z pinch is subject to magnetic Rayleigh-Taylor (MRT) instability, which must be suppressed for pract…
