Electrodynamic phenomena induced by a dark fluid: Analogs of pyromagnetic, piezoelectric, and striction effects

摘要: We establish a new model of coupling between cosmic dark fluid and electrodynamic systems, based on an analogy with effects electric magnetic striction, piezoelectricity piezomagnetism, pyroelectricity pyromagnetism, which appear in classical electrodynamics continuous media. Extended master equations for electromagnetic gravitational fields are derived using Lagrange formalism. A cosmological application the is considered, it shown that striction-type interaction energy (the main constituent fluid) system provides universe history to include so-called unlighted epochs, during waves cannot propagate thus scan interior.
