Nonlinear wave in plasma when electrons spin is considered.

What is it about?

Nonlinear waves such as shocks may arise in plasma due to perturbation. Here the ions are considered classical and electrons are taken quantum particles, where their spin is also considered. It is shown that the spin and cylindrical geometry play an important role to change the amplitude and velocity of shocks produced in plasma.

Why is it important?

Such dense plasma exists in stellar atmospheres like white dwarfs and neutron stars etc., so this study explains how the nonlinear structures may behave in such systems. Our findings show that spin and geometrical effects change the shape of these shocks.
