Force law in material media and quantum phases

We show that the known expressions for the force on a point-like dipole are incompatible with the relativistic transformation of force, and in this respect we apply the Lagrangian approach to the derivation of the correct equation for force on a small electric/magnetic dipole. The obtained expression for the generalized momentum of a moving dipole predicts two novel quantum effects with non-topological and non-dynamic phases, when an electric dipole is moving in an electric field, and when a magnetic dipole is moving in a magnetic field, correspondingly. The implications of the obtained results are discussed.

Mossbauer Experiment in a Rotating System on the Time Dilation Effect

We present results of Moessbauer experiment in a rotating system, which is induced by our recent disclosure (Phys. Scr., 77 (2008) 035302) and which consisted in the fact that a correct processing of Kundig experiment data on the subject gives an appreciable deviation of a relative energy shift dE/E between emission and absorption resonant lines from the standard prediction based on the relativistic dilation of time (that is dE/E=-v2/2c2 to the accuracy c-2, where v is the tangential velocity of absorber of resonant radiation, and c is the light velocity in vacuum). Namely, the Kundig result following the correction we brought to it, is dE/E=-(0.596+/-0.006)v2/c2. In our own experiment we carried out measurements for two absorbers with substantially different isomer shift, which allowed us to make a correction of Moessbauer data to a level of vibrations in the rotor system at various rotational frequencies. As a result we got the estimation dE/E=-(0.68+/-0.03)v2/c2. A deviation from the relativistic formula is discussed.

The Faraday induction law in relativity theory

We analyze the transformation properties of Faraday law in an empty space and its relationship with Maxwell equations. In our analysis we express the Faraday law via the four-potential of electromagnetic field and the field of four-velocity, defined on a circuit under its deforming motion. The obtained equations show one more facet of the physical meaning of electromagnetic potentials, where the motional and transformer parts of the flux rule are incorporated into a common phenomenon, reflecting the dependence of four-potential on spatial and time coordinates, correspondingly. It has been explicitly shown that for filamentary closed deforming circuit the flux rule is Lorentz-invariant. At the same time, analyzing a transformation of e.m.f., we revealed a controversy: due to causal requirements, the e.m.f. should be the value of fixed sign, whereas the Lorentz invariance of flux rule admits the cases, where the e.m.f. might change its sign for different inertial observers. Possible resolutions of this controversy are discussed.
