On generalized entropies and information-theoretic Bell inequalities under decoherence
Alexey E. Rastegin
We consider information-theoretic inequalities of the Bell type in the presence of decoherence. It is natural that too strong coupling with the environment can prevent an observati…
On uncertainty relations and entanglement detection with mutually unbiased measurements
Alexey E. Rastegin
We formulate some properties of a set of several mutually unbiased measurements. These properties are used for deriving entropic uncertainty relations. Applications of mutually unb…
High-energy neutrino fluxes and flavor ratio in the Earth's atmosphere
T. S. Sinegovskaya, A. D. Morozova, S. I. Sinegovsky
We calculate the atmospheric neutrino fluxes in the energy range GeV -- PeV with the use of several known hadronic models and a few parametrizations of the cosmic ray sp…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. III. Catastrophe of the Eruptive Filament at a Magnetic Null Point and Formation of an Opposite-Handedness CME
A. M. Uralov, V. V. Grechnev, G. V. Rudenko +4
Our analysis in Papers I and II (Grechnev et al., 2014, Solar Phys. 289, 289 and 1279) of the 18 November 2003 solar event responsible for the 20 November geomagnetic superstorm ha…
Search for neutrino emission from relic dark matter in the Sun with the Baikal NT200 detector
A. D. Avrorin, A. V. Avrorin, V. M. Aynutdinov +49
We have analyzed a data set taken over 2.76 years live time with the Baikal neutrino telescope NT200. The goal of the analysis is to search for neutrinos from dark matter annihilat…
Formulation of Leggett-Garg inequalities in terms of -entropies
Alexey E. Rastegin
As is well known, the macroscopic realism and the noninvasive measurability together lead to Leggett-Garg inequalities violated by quantum mechanics. We consider tests of the Legge…
