Macroscopic realizations of quantum logics

Summary Two-particle quantum systems with spin can be simulated by classical automata described by graphs. These graphs are associated with nondistributive property lattices of these quantum systems. We emphasize that to non-local properties of a quantum system being in a certain eigenstate of the permutation operator there correspond merely some additional vertices in the graph which have nothing nonlocal in their nature. This leads to the possibility of violating Bell's inequalities in classical systems described by graphs (see Section 6) without violating relativity theory.The subjective interpretation of quantum mechanics of von Neumann, London, and Bauer can be connected with the Boolean nature of mind grasping the non-Boolean nature of the world, which results in the projection postulate: wave packet reduction. A simple example is given for a two-particle system with spin.     

Static Limit and Penrose Effect in Rotating Reference Frames

Theoretical and Mathematical Physics - We show that effects similar to those for a rotating black hole arise for an observer using a uniformly rotating reference frame in a flat space-time: a...     

Studying the physical properties of entangled electron spin states in a solid body

A concept for the experimental study of the physical properties of entangled electron spin states in a solid body is proposed. The construction of the experimental setup is developed. New-generation electron spin detectors are created. Test measurements of the electron spin polarization by two simultaneously operating Mott detectors are carried out. It is found that Bell’s inequalities are satisfied in the traditional measurement mode (without time coincidences of the pulses).

Subgap excitations in an irregular superconducting<Emphasis Type="Italic">S/I</Emphasis> superlattice in the current-carrying state

The spectrum of a superconductor/insulator superlattice in the current-carrying state in the case when one barrier potential is different from the others has been studied. The presence of a defect leads to a localized quasiparticle state displaced from the band. The energy of this state is expressed in terms of the tunneling probability of the defective barrier and supercurrent.
