This tutorial covers recent developments in the field of dusty (complex) plasmas. After a brief summary of fundamental concepts, this tutorial will focus on novel diagnostics in dusty plasmas which have proven to be important tools on the route towards studying magnetized and polydisperse dust systems. These two hot topics of dusty (complex) plasma research are introduced, the current understanding is presented and open questions are identified. This tutorial is from an experimentalists’ perspective. Hence, the recent experimental progress in diagnostics, as well as in magnetized and polydisperse systems is described and discussed.

“…Such a behaviour of dust particles is conventionally interpreted as a liquid or even crystalline state, which provides a whole range of means for testing theoretical concepts specifically developed for many‐body systems with strong interparticle interactions . For example, first and second order phase transitions were theoretically predicted and experimentally observed for the dust component, while even defects in plasma crystals were discovered with the aid of laser interferometry, which could significantly affect the dust transport properties …”

The aim of the present study is to determine the impact the finite size of dust particles has on the static and dynamic characteristics of the dust component of a plasma.Taking into account both the finite dimensions of dust grains and the plasma screening, a model expression is chosen for the interdust interaction potential. The static structure factor of dust particles is evaluated by iteratively solving the reference hypernetted-chain approximation, which inherently contains the hard sphere model handled within the Percus-Yevick closure. The self-consistent method of moments is then engaged to relate the static and dynamic structure factors by assuming that the second derivative of the dynamic structure factor with respect to the frequency vanishes at the origin. Thus, an analytical expression for the dynamic structure factor is validated over quite a broad domain of dusty plasma non-ideality and grains packing fraction. The calculated spectrum of dust-acoustic waves reveals the appearance of the roton minimum, which becomes less pronounced when the packing fraction of dust particles rises. It is also predicted that the wavenumber position of the roton minimum is de facto independent of the size of dust particles. New analytical expressions for the dust-acoustic wave spectrum and decrement of damping are proposed and thoroughly checked.
