Abstract
A nonlinear Schrödinger equation which governs the nonlinear interaction
of the ion-acoustic wave with the quasistatic plasma slow response in a
magnetised plasma is deduced. The magnetic field is assumed to be constant. It
is observed that the coefficient of the nonlinear term in the derived
nonlinear Schrödinger equation turns out to be complex, in contrast to
the usual situation. The condition for modulational stability is derived and
it is found to be somewhat different. In the final section such a condition is
discussed graphically. Our NLS equation goes back to that of the unmagnetised
case if wc is put to zero.
