<title>Variation of power-law dynamics caused by dark state recovery of fluorescence intermittency of a single quantum system</title>

This paper is aimed to dissociate nonlocality from quantum theory. We demonstrate that the tests on violation of the Bell type inequalities are simply statistical tests of local incompatibility of observables. In fact, these are tests on violation of the Bohr complementarity principle. Thus, the attempts to couple experimental violations of the Bell type inequalities with “quantum nonlocality” is really misleading. These violations are explained in the quantum theory as exhibitions of incompatibility of observables for a single quantum system, e.g., the spin projections for a single electron or the polarization projections for a single photon. Of course, one can go beyond quantum theory with the hidden variables models (as was suggested by Bell) and then discuss their possible nonlocal features. However, conventional quantum theory is local.

Inspired by the phenomenon of fluorescence intermittency in quantum dots and other materials, we introduce small off-states (intermissions) which interrupt the generation and recombination (= [Formula: see text]–[Formula: see text]) process in a semiconductor material. If the remaining on-states are power-law distributed, we find an almost pure 1/[Formula: see text] spectrum. Besides well-known [Formula: see text]–[Formula: see text] noise, we obtain two 1/[Formula: see text] noise components which can be attributed to the intermittent generation and recombination process. These components can be given the form of Hooge's relation with a Hooge coefficient [Formula: see text] describing the contribution of the generation and recombination process, respectively. Herein, the coefficients [Formula: see text] and [Formula: see text] describe impact of intermissions which in general are different for the generation and recombination process. The impact of [Formula: see text]–[Formula: see text] noise on 1/[Formula: see text] noise is comprised in the coefficient [Formula: see text] for the generation and [Formula: see text] for the recombination process. These coefficients are specified for an intrinsic and a slightly extrinsic semiconductor as well as for a semiconductor with traps; for the latter, the temperature dependence of 1/[Formula: see text] noise is also investigated. 1/[Formula: see text] noise is shown to be inversely related to the number of neutral and ionized [Formula: see text]-atoms rather than to the number of conduction electrons as defined in Hooge's relation. As a possible origin of 1/[Formula: see text] noise in semiconductors, electron–phonon scattering is suggested.

Basic Representation

The group theoretical description of the periodic system of elements in the framework of the Rumer–Fet model is considered. We introduce the concept of a single quantum system, the generating core of which is an abstract C*-algebra. It is shown that various concrete implementations of the operator algebra depend on the structure of the generators of the fundamental symmetry group attached to the energy operator. In the case of the generators of the complex shell of a group algebra of a conformal group, the spectrum of states of a single quantum system is given in the framework of the basic representation of the Rumer–Fet group, which leads to a group-theoretic interpretation of the Mendeleev’s periodic system of elements. A mass formula is introduced that allows giving the termwise mass splitting for the main multiplet of the Rumer–Fet group. The masses of elements of the Seaborg table (eight-periodic extension of the Mendeleev table) are calculated starting from the atomic number Z=3 and going to Z=220. The continuation of the Seaborg homology between lanthanides and actinides is established with the group of superactinides. A 10-periodic extension of the periodic table is introduced in the framework of the group-theoretic approach. The multiplet structure of the extended table’s periods is considered in detail. It is shown that the period lengths of the system of elements are determined by the structure of the basic representation of the Rumer–Fet group. The theoretical masses of the elements of 10th and 11th periods are calculated starting from Z=221 and going to to Z=364. The concept of hypertwistor is introduced.
