Real Matrix Representations of Quantum Operators: An Introduction to Quantum Index Algebra
A. Yu. Volkov, G. A. Koroteev, Yu. S. Volkov
We introduce Quantum Index Algebra (QIA) as a finite, index-based algebraic framework for representing and manipulating quantum operators on Hilbert spaces of dimension . In Q…
Bell, Spinors, and the Impossibility of a Classical Spin-Vector Model
G. A. Koroteev
We revisit the Bell--CHSH scenario for two spin-\(\tfrac{1}{2}\) particles and isolate the precise algebraic origin of the Bell contradiction. On the quantum side, spin-\(\tfrac{1}…
Quasi-van Hove singularities informed approach improving DOS/pDOS predictions in GNN
Grigory Koroteev
In this paper, we introduce an extension of the concept of Van Hoff singularities in order to explicitly use them in machine learning methods of models as a priori information. The…
Cross sections of solar neutrino capture by 127I nuclei and Gamow Teller resonances
Yu. S. Lutostansky, A. N. Fazliakhmetov, G. A. Koroteev +3
Solar neutrino capture cross-section by 127I nucleus has been studied with taking into account the influence of the resonance structure of the nuclear strength function S(E). Three…
Resonances in the solar neutrino capture cross-section for nuclei
A. N. Fazliakhmetov, L. V. Inzhechik, G. A. Koroteev +3
The calculation results of solar neutrino capture cross-section on the nucleus are presented. The charge-exchange strength function was obtained from the experimen…
