In view of the probabilistic quantizer–dequantizer operators introduced, qubit states (spin-1/2 particle states, two-level atom states) realizing irreducible representation S U ( 2 ) symmetry group are identified with probability distributions (including conditional ones) classical-like dichotomic random variables. The variables spin-1/2 projections m = ± 1 / onto three perpendicular directions in space. invertible maps density fair constructed. suggested quantum Schrödinger and von Neumann...
We review the method of quantizers and dequantizers to construct an invertible map density operators onto functions including probability distributions discuss in detail examples qubit qutrit states. The biphoton states existing process parametric down-conversion are studied representation quantum mechanics.
To permit unified analysis and simultaneous evaluation of geometrical spin-redirection phase Pancharatnam phase, the conventional 2×2 Jones matrix calculation is generalized a new scheme 3×3 proposed. With proposed algorithm one can trace polarization state changes geometric shifts caused by beam propagation along an arbitrary optical path that involves both reflection refraction at surfaces with Fresnel shift birefringence.
The method allowing one to achieve sub-Rayleigh resolution in optical interferometric microscopy is offered. It shown that for this purpose it not necessary overcome the diffraction limit. Generally speaking, "sub-Rayleigh resolution" and "overcoming of limit" are essentially different concepts. Our uses modulation all parameters a light source separation phase shifts origin. worked out makes possible measure phases separately and, therefore, determine related characteristics an object....
The generalization of Einstein’s special theory relativity (SRT) is proposed. In this model, the possibility unification scalar gravity and electromagnetism into a single unified field considered. Formally, SRT that instead (1+3)-dimensional Minkowski space (1+4)-dimensional extension G As fifth additional coordinate interval S used. This value saved under usual Lorentz transformations in M, but it changes when extended are We call model (ESM). From physical point view, our expansion means...
