This book concerns the physics of plasma at high density, which is compressed so strongly that the effects of interparticle interactions, nonideality, govern its behavior. The interest in this non-traditional plasma has emerged during the last few years when states of matter with high concentration of energy, constituting the basis of the modern technologies and facilities, became accessible for impulse experiments. The greatest part of the Universe matter is in this exotic state. In this book, the methods of strongly coupled plasma generation and diagnostics are considered. The experimental results on thermodynamic, kinetic, and optical properties are given, and the main theoretical models of the strongly coupled plasma state are discussed. Particular attention is given to fast developing modern directions of strongly coupled plasma physics, such as metallization of dielectrics and dielectrization of metals, nonneutral plasma, complex (dusty) plasma, and its crystallization.

An observation of low frequency waves spontaneously excited in a dc glow discharge dusty plasma is reported. To analyze possible reasons for the instability observed, a linear dispersion relation which takes into account collisions with neutrals, dust grain charge variations, ion drift, and forces acting on dust particles is derived. Numerical analysis of the dispersion relation shows that the observed instability is the result of dust charge variations in the presence of external charge-dependent forces together with the ion drift effect.

The spontaneous excitation of low-frequency oscillations of the macroparticle density in ordered dust structures levitating in standing striations of a dc glow discharge is discovered. It is...
