Torsion heating in complex plasma crystals.
The study of plasma has yielded advancements in fields ranging from manufacturing to medicine for millions worldwide. A subfield of plasma study involves introducing microparticles to plasma, forming a newer field called complex/dusty plasmas. Complex plasmas host analogous structures to naturally …

Modeling the influence of ion wakes on the self-organization of dust in a complex plasma.
… between charged dust grains and streaming plasma leads to the formation of ion wakes, which are thought to be responsible for the self-organization of dust into complex structures. These structures have been observed to exhibit long-range stability both in ground-based and microgravity …

The study of overlapping sheath and dust particle structures in dusty plasma.
Complex (dusty) plasma consists of plasma and dust particles which vary in size from nanometer to millimeter in diameter. Complex plasma exists across many different environments, and can be found in environments from the cosmos to industry. Due to plasma fluxes to its surface, a dust particle …

Experimental probe-induced complex RF plasma phenomena.
Plasma has long been studied in its own right as a state of matter, but the addition of particles large compared to its basic constituents yields a host of complicated behavior that was not predicted theoretically. Levitated micrometer-sized particles in the sheath of a RF plasma have previously …

Nanomanipulator perturbation of dust crystals in a GEC rf plasma cell.
… majority of observable matter is composed of complex plasma. Even with its prevalence, the interactions between the plasma's constituents are not fully understood. In many cases, clouds of dust grains from and can even display organized, crystal-like, structures. Understanding the …
