A brief review of studies on nonlinear wave structures in dusty plasmas is presented, for which effects that appear specifically in dusty plasmas, for example, anomalous dissipation associated with the processes of dust particle charging, are presented. Examples of such structures in laboratory and space plasmas are given. In particular, a description is presented of the experiments at the Institute of Space and Astronautical Sciences (Japan) and at the University of Iowa (USA). A significant accent is made to space research, namely, the formation of bow shock arising from the interaction of the comet’s dust coma and the solar wind, and the formation of a nonlinear structure in the region of the lunar terminator.

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

Radiation from rotational transitions of CO molecules in distant galaxies creates a chaotic background with an intensity reaching 1000 Jy/sr at a wavelength of approximately 1 mm. This background will pose a serious problem, when measuring spectral distortions of the cosmic microwave background, in particular, the mu-distortion, which presumably has an intensity of less than ...

This work presents a comprehensive investigation into the temperature-dependent thermally stimulated conductivity and photoconductivity of vacuum-annealed thin films based on core–shell CdSe/CdS nanoplatelets passivated with oleic acid ligands. Controlled thermal annealing under vacuum conditions leads to a substantial increase in both dark and photoinduced conductivity, which is primarily attributed to partial desorption of the ligands. ...
