Characterizing the temporal evolution of Biermann-battery-driven magnetic reconnection in laser-ablated plasmas
T. Morita, Y. Muramoto, S. Isayama +30
This paper presents an experimental investigation of magnetic reconnection between two laser-produced expanding plasmas, focusing on the quantitative evaluation of the reconnection…
Relativistic multistage resonant and trailing-field acceleration induced by large-amplitude Alfvén waves in a strong magnetic field
S. Isayama, S. Matsukiyo, T. Sano +1
We propose a particle acceleration mechanism driven by large-amplitude Alfvén waves in a strong magnetic field. The acceleration process proceeds through multiple stages triggered…
Nonlocal Evolution of Magnetic Helicity across the Magnetohydrodynamic-Kinetic Interface
Masatomi Iizawa, Yasuhito Narita, Tommaso Alberti +6
Magnetic helicity is typically indistinguishable from noise in the solar wind inertial range. Using Parker Solar Probe measurements (0.1-0.8 au), we report a robust bihelical struc…
Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma
S. Matsukiyo, K. Oshida, S. Isayama +7
Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma is investigated by using one-dimensional full particle-in-cell simulation…
Injection process of pickup ion acceleration at an oblique heliospheric termination shock
S. Matsukiyo, Y. Matsumoto
Injection process of pickup ion acceleration at a heliospheric termination shock is investigated. Using two-dimensional fully kinetic particle-in-cell simulation, accelerated picku…
Competition of magnetic reconnections in self-generated and external magnetic fields
K. Sakai, T. Y. Huang, N. Khasanah +13
We investigate the competition of magnetic reconnections in self-generated and external magnetic fields in laser-produced plasmas. The temporal evolution of plasma structures measu…
Linearly-polarized Coherent Emission from Relativistic Magnetized Ion-electron Shocks
Masanori Iwamoto, Yosuke Matsumoto, Takanobu Amano +2
Fast radio bursts (FRBs) are millisecond transient astrophysical phenomena and bright at radio frequencies. The emission mechanism, however, remains unsolved yet. One scenario is a…
Exact Calculation of Nonideal Fields Demonstrates Dominance of Injection in Relativistic Reconnection
Samuel R. Totorica, Seiji Zenitani, Shuichi Matsukiyo +3
Magnetic reconnection is an important source of energetic particles in systems ranging from astrophysics to the laboratory. The large separation of spatiotemporal scales involved m…
Ion-acoustic feature of collective Thomson scattering in non-equilibrium two-stream plasmas
K. Sakai, T. Nishimoto, S. Isayama +2
We theoretically and numerically investigate the ion-acoustic features of collective Thomson scattering (CTS) in two-stream plasmas. When the electron distribution functions of two…
Detection of current-sheet and bipolar ion flows in a self-generated antiparallel magnetic field of laser-produced plasmas for magnetic reconnection research
T. Morita, S. Matsukiyo, S. Isayama +18
Magnetic reconnection in laser-produced magnetized plasma is investigated by using optical diagnostics. The magnetic field is generated via Biermann battery effect, and the inverse…
Nonthermal Electron Acceleration at Collisionless Quasi-perpendicular Shocks
T. Amano, Y. Matsumoto, A. Bohdan +6
Shock waves propagating in collisionless heliospheric and astrophysical plasmas have been studied extensively over the decades. One prime motivation is to understand the nonthermal…
High-power laser experiment on developing supercritical shock propagating in homogeneously magnetized plasma of ambient gas origin
S. Matsukiyo, R. Yamazaki, T. Morita +30
A developing supercritical collisionless shock propagating in a homogeneously magnetized plasma of ambient gas origin having higher uniformity than the previous experiments is form…
Particle acceleration by counter-propagating circularly polarized Alfvén waves
S. Isayama, K. Takahashi, S. Matsukiyo +1
Counterpropagating Alfvén waves are ubiquitously observed in many astrophysical environments, such as a star surface and a planetary foreshock. We discuss an efficient particle acc…
