Successive Generations of Dust in Complex Plasmas: A Cyclic Phenomenon in the Void Region
Description :
Dust formation and growth in plasmas are in most cases continuous cyclic phenomena. We show that the growth of new dust generations takes place in a dust-free region, usually called a void, in the dust cloud. The three-step process of new dust generation is detailed thanks to the correlation between...

Description :
In complex plasmas, the trapped dust particle cloud is often characterized by a central dust-free region (”void”). The void induces a spatial inhomogeneity of the dust particle distribution and is at the origin of many intricate unstable phenomena. One of this behavior is the so-called heartbeat ins...

Description :
Instabilities in dusty plasmas are frequent phenomena. We show that some instabilities can be described by mixed-mode oscillations often encountered in chemical systems or neuronal dynamics and studied through dynamical system theories. The time evolution of these instabilities is studied through th...
