Experimental Status Report on Vector Meson Spectroscopy

The experimental status of light vector meson spectroscopy is discussed. The last results of $e^+e^-$ experiments obtained at the VEPP-2M collider in Novosibirsk are described and the comparison with the old data in the mass region from 1 GeV to 2.5 GeV is performed.Comment: 6 pages, 13 figures, e^+e^- Physics at Intermediate Energies, Workshop - Contribution T0

Non-equilibrium reversible dynamics of work production in four-spin system in a magnetic field

A closed system of the equations for the local Bloch vectors and spin correlation functions is obtained by decomplexification of the Liouville-von Neumann equation for 4 magnetic particles with the exchange interaction that takes place in an arbitrary time-dependent external magnetic field. The analytical and numerical analysis of the quantum thermodynamic variables is carried out depending on separable mixed initial state and the magnetic field modulation. Under unitary evolution, non-equilibrium reversible dynamics of power production in the finite environment is investigated.Comment: 12 pages, 3 figures, published version, title change

Technological Singularity

Hypothetically, technological singularity is considered as irreversible changes to the mankind resulted from technological growth due to the invention of artificial super intelligence (AI). The major concern is that AI will come out of the control and, finally, humanity will be deprived of their position in the world
