Derivation of the robustness from the concurrence
Yu. S. Krynytskyi, A. R. Kuzmak
Adding the maximally mixed state with some weight to the entanglement system leads to disentanglement of the latter. For each predefined entangled state there exists a minimal valu…
Geometry and speed of evolution for a spin-s system with long-range zz-type Ising interaction
Yu. S. Krynytskyi, A. R. Kuzmak
We study the evolution of a spin-s system described by the long-range zz-type Ising interaction. The Fubini-Study metric of the quantum state manifold defined by this evolution is…
Multipole expansions for time-dependent charge and current distributions in quasistatic approximation
Yuri Krynytskyi, Andrij Rovenchak
We propose a consistent approach to the definition of electric, magnetic, and toroidal multipole moments. Electric and magnetic fields are split into potential, vortex, and radiati…
Radiation of the electromagnetic field beyond the dipole approximation
Andrij Rovenchak, Yuri Krynytskyi
The expression for the intensity of the electromagnetic field radiation is derived in the approximation next to the dipole one. The presented approach is based on fundamental equat…
