Alternative Form of the Parity-Violating Current for the Hyperon Weak Radiative Decays and Hara Theorem
E. N. Bukina, V. M. Dubovik, V. S. Zamiralov
It is shown that upon considering an alternative form of a parity-violating part of the transition electromagnetic current it is possible to reformulate Hara theorem in a way that…
The gauge freedoms of enlarged Helmholtz theorem and the Neumann --- Debye potentials; their manifestation in the multipole expansion of conserved current
E. N. Bukina, V. M. Dubovik
We discuss gauge freedom within the scope of the enlarged Helmholtz theorem and Neumann-Debye decomposition and then demonstrate its realization for the multipole expansion of a el…
Upon symmetry of baryon magnetic moments in the chiral and the quark-soliton models
E. N. Bukina, V. M. Dubovik, V. S. Zamiralov
It is shown that the baryon magnetic moment descriptions in the frameworks of the chiral model ChPT and the quark soliton one are practically identical. The main difference…
Electrodymanics of Moving Continuous Media with Toroid Polarization
V. M. Dubovik, B. Saha
With regard to the toroid contributions, a modified system of equations of electrodynamics moving continuous media has been obtained. Alternative formalisms to introduce the toroid…
Electrodymanics with Toroid Polarization
V. M. Dubovik, B. Saha
A modified system of equations of electrodynamics has been obtained. Beside the Lagrangian one an alternative gauge-like formalism has been developed to introduce the toroid moment…
Multipolar Representation of Maxwell and Schroedinger Equations: Lagrangian and Hamiltonian Formalisms: Examples
V. M. Dubovik, M. A. Martsenyuk, B. Saha
Development of quantum engineering put forward new theoretical problems. Behavior of a single mesoscopic cell (device) we may usually describe by equations of quantum mechanics. Ho…
