Nonlocal magnetic-field generation in plasmas without density gradients.

Abstract:

Conventional theories of magnetic-field generation by laser pulses in collisional plasmas require the presence of density gradients or anisotropic pressure. Using the first two-dimensional Fokker-Planck code to self-consistently include magnetic fields, we find that magnetic fields can be spontaneously generated when a collisional plasma is nonuniformly heated even though inverted delta n = 0 and the pressure is purely isotropic. These magnetic fields, which can become strong enough to signif...
