Quantum superposition principle reformulation and collapse of wave function explanation
I. G. Koprinkov
The quantum superposition principle is reexamined and reformulated based on the adiabatic theorem of quantum mechanics, nonadiabatic dressed states and experimental evidences. The…
Influence of anisotropic matter on the Alcubierre metric and other related metrics: revisiting the problem of negative energy
G. Abellan, N. Bolivar, I. Vasilev
Negative energy scenarios are the most widely studied for the warp metric. In fact, the prevailing view in the community so far has been that the warp metric necessarily has negati…
A modification of Oersted experiment
Dimitar G Stoyanov
The paper describes a simple setup of Oersted experiment. A planar coil of wires has been used to deflect vigorously the magnetic needle (more than 80 angular degrees) when a curre…
Analytical form of current-voltage characteristic of parallel-plane, cylindrical and spherical ionization chambers with homogeneous ionization
Dimitar G. Stoyanov
The elementary processes taking place in the formation of charged particles and their flow in parallel-plane, cylindrical and spherical ionization chambers are considered. On the b…
Current-voltage characteristic of parallel-plane ionization chamber with inhomogeneous ionization
Dimitar G. Stoyanov
The balances of particles and charges in the volume of parallel-plane ionization chamber are considered. Differential equations describing the distribution of current densities in…
