The scattering of light on isotropic spherical metal scatterers illuminated by radially, azimuthally polarized Laguerre-Gaussian modes and LG modes with circular polarization using Lorentz-Mie theory is described. It is shown that any superposition of Laguerre-Gauss modes with topological charge 1 can be considered as the sum of LG modes with radial, azimuthal, and circular polarization (with the same sign of spin and orbital angular momentum). A scheme of a single-photon quantum switcher of state-controlled qubit formed by a pair of the lowest levels of a cascade three-level system is proposed. A potential variant of the experimental realization of this switcher on superconducting elements is considered. It is demonstrated that the device parameters required to achieve high switching contrasts are achievable for modern superconducting systems. The nonlinear effects of collective gas scattering due to the blockade effect were used to describe the instability in the socioeconomic system caused by an epidemic-like shock. Based on the agent-oriented model of the trivial socio-economic system, it is shown that the activation type mechanism of coupling between the epidemic spreading process and the system resource can lead to the effect of collapse, as opposed to the thermal explosion. It is shown that the phase diagram of the system has a tricritical point. A more general model (in the approximation of slow times) with an expanded space of internal states of agents is proposed the kinetics of which takes into account local spatiotemporal fluctuations of agent density. It gives an advantage in the construction of various control strategies to minimize the effect of the epidemic and can be used to model spreading processes of epidemic, informational, or other nature.
