Magnetic field generation and diffusion by a laser-produced blast wave propagating in non-homogenous plasma

Time evolution and asymmetry of a laser produced blast wave

Observation of Bernstein Wave Propagating Obliquely to the Magnetic Field in a Streaming Plasma

Bernstein wave propagating obliquely to the magnetic field is excited by a coaxial antenna in a streaming plasma and detected by the interferometer system, which shows that the dispersion relation for the wave is consistent with the theoretical result. The other wave-like signal with shorter 'wavelength' is observed only on the downstream of the exciting antenna and its 'phase velocity' is appr...

Propagating magneto-hydrodynamic waves in a cooling homogenous coronal plasma

Aims. We present an investigation into how the cooling of the background plasma influences the propagation of slow and fast MHD wave modes supported by an unbounded, homogenous plasma. Previous investigations have suggested that the cooling of the plasma and a reduction in density could lead to the damping of fast magneto-acoustic oscillations. We aim to investigate whether cooling of the backg...

Generation of High Order Harmonics from H2+ Molecule Ion by Using Homogenous and Inhomogeneous Laser Fields

We solved one dimensional Schrodinger equation in a H2+ molecular environment by using 3 femtosecond homogeneous and nonhomogeneous laser fields. In homogeneous case, we found out that larger inter nuclear distances result in earlier ionization and also more instability in the wave packet. We deducted that the more the instability is, the more modulated the power spectrum will be. So, by choosi...

Steady magnetic-field generation via surface-plasma-wave excitation.

The possibility of inducing a magnetic field via surface plasma-wave excitation is investigated with a simple nonrelativistic hydrodynamic model. A static magnetic field is predicted at the plasma surface, scaling with the square of the surface-wave field amplitude, and the influence of the electron plasma density is studied. In the case of resonant surface-wave excitation by laser this result ...
