“…Ions and neutrals are, as a rule, at room temperature. Even in the gas discharge at cryogenic conditions [66][67][68][69], with heavy particle temperatures ∼ 10 K, ions and electrons remain too hot for manifestation of quantum effects [70,71]. The dust particles that form inside a gas discharge plasma eventually fall down on the surface of a plate (which is usually metallic in industrial plasma reactors) [72,73]; thereby "contaminating" the micro-or nano-device.…”

During the recent decade a steadily increasing number of papers devoted to so-called "quantum dusty plasmas" (QDP) appeared. These systems are combining the properties of dusty (i.e. micrometer to nanometer-sized particles containing) plasmas with quantum effects appearing at high-density and/or low-temperature. Many exciting properties of QDP were predicted including nontrivial collective oscillations and linear and nonlinear waves. It was predicted that the results have relevance for dense astrophysical plasmas such as white dwarf stars, neutron stars, magnetars and laboratory plasmas in micro-and nano-devices. Here we present a careful examination of the plasma parameters for the expected applications and compare them to the conditions under which a dust particle can exist in a quantum plasma. The conclusion is that quantum dusty plasmas do not exist in reality.
