Modulation Nonlinear Generation of the Magnetic Fields in a Dense Plasma

Abstract: The effect of generation of a magnetic field by modulational instability of strong electrostatic waves is generalized for the case of frequent electron-ion collision. Selfconsistent nonlinear equations for magnetic and electrostatic fields are obtained for the case when the characteristic wave-length is much larger than the electron mean free path for binary collisions. Magnetic field generation is examined in this case. The spectrum of field fluctuations is calculated.

“…11 Over the last decades, high power laser beams have been used in a large number of physical investigations of laserplasma interactions, such as the fast ignitor concept in the laser fusion research. 13 They are produced due to the nonponderomotive component of the nonlinear current, i.e., the magnetization current, as a typical reaction of the plasma to nonlinear excitations. 13 They are produced due to the nonponderomotive component of the nonlinear current, i.e., the magnetization current, as a typical reaction of the plasma to nonlinear excitations.…”

“…A complication lies in taking into account both transverse and longitudinal virtual waves (even when considering only transverse pump waves). It should be noted that, in general, transverse virtual fields should be taken into consideration even when only longitudinal pump waves interact (see Bel'kov & Tsytovich 1979, Kono, Skoric & ter Haar 1980. We have chosen here a model including only longitudinal perturbations for the sake of simplicity; besides, in a number of situations (e.g.…”

“…The low-frequency fields nonlinearly generated by high-frequency waves in a plasma has been the subject of much studies during several decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The focus has been on the ponderomotive force, see e.g.…”

“…The focus has been on the ponderomotive force, see e.g. [1,2], on heating nonlinearities due to collisional effects [3], or on the possibility to generate quasi-static magnetic fields [4][5][6][7][8][9][10][11][12][13][14][15]. Generation of such fields has proven to be rather sensitive to small deviations from the classical collisionfree Vlasov model.…”
