ABSTRACT
A first theoretical attempt is made to present a relativistic generalization of the well-known orbit-limited motion theory. The appropriate relativistic (electron and ion) dust charging currents are derived. The nonlinear electrostatic potential is then expressed in terms of the variable dust charge and we take advantage of this new transcendental relation to investigate briefly the effects of relativistic charge carriers. As the relativistic character of the plasma increases, it becomes evident that certain negative values of the dust charge can never be achieved as increasingly larger values of the nonlinear potential are involved. The obtained formulas bring a possibility to build theories of nonlinear collective process in relativistic dusty plasmas.

    The Child–Langmuir law relates the voltage applied across a planar diode to the saturation value J[sub CL] of current density that can be transmitted through it in case the injection velocity of electrons is zero. The Child–Langmuir current density J[sub CL] is, at the same time:...

    Repeated transition phenomena (flip-flop pattern) with abrupt reductions and jumps of the electron density was observed, by the voltage biasing to an electrode in the cylindrical magnetized plasma. These global, self-excited, dynamical density transitions in bistable system were accompanied by...

    It is shown that, in the tokamak plasmas with broad low-shear central core and safety factor q0>=1, there exists a low-frequency global Alfvén eigenmode capable of resonating with precession of the trapped energetic ions. This mode has the dominant numbers m=n=1, but the coupling with the...
