被引用回数:24 パーセンタイル:86.99(Physics, Fluids & Plasmas)The magnetic quadrupole structure formation during the interaction of two ultrashort high power laser pulses with a collisionless plasma is demonstrated with 2.5-dimensional particle-in-cell simulations. The subsequent expansion of the quadrupole is accompanied by magnetic-field annihilation in the ultrarelativistic regime, when the magnetic field cannot be sustained by the plasma current.

被引用回数:3 パーセンタイル:13.86(Physics, Fluids & Plasmas)Using particle-in-cell computer simulations we have studied the electromagnetic relativistic soliton formation in the underdense multi-species plasmas irradiated by high power laser radiation. It has been shown that in a multi-species plasma the light ion acceleration is quite efficient.

被引用回数:8 パーセンタイル:41.4(Physics, Fluids & Plasmas)The magnetic field generated by the laser pulses annihilates in a current sheet formed between the pulses. Magnetic field energy is converted to an inductive longitudinal electric field, which efficiently accelerates the electrons of the current sheet. This new regime of collision less relativistic magnetic field annihilation with a timescale of tens of femtoseconds can be extended to near-critical and overdense plasma with the ultra-high intensity femtosecond laser pulses.
