Perturbational Analysis of Magnetic Force Theorem for Magnetic Exchange Interactions in Molecules and Solids [PDF]

open access: yesMolecules
There have been increasing efforts to compute magnetic exchange coupling constants for transition metal complexes and magnetic insulators using the magnetic force theorem and Green’s function-based linear response methods. These were originally conceived

Comment on ‘Quantum correlations are weaved by the spinors of the Euclidean primitives’ [PDF]

open access: yesRoyal Society Open Science, 2022
I point out fundamental mathematical errors in the recent paper published in this journal ‘Quantum correlations are weaved by the spinors of the Euclidean primitives’ by Joy Christian.

On the k-Fibonacci and k-Lucas spinors [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper, we introduce a new family of sequences called the k-Fibonacci and k-Lucas spinors. Starting with the Binet formulas we present their basic properties, such as Cassini’s identity, Catalan’s identity, d’Ocagne's identity, Vajda's identity ...

Quantum correlations are weaved by the spinors of the Euclidean primitives [PDF]

open access: yesRoyal Society Open Science, 2018
The exceptional Lie group E8 plays a prominent role in both mathematics and theoretical physics. It is the largest symmetry group associated with the most general possible normed division algebra, namely, that of the non-associative real octonions, which—

Subliminal aspects concerning the Lounesto’s classification

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the present communication we employ a split programme applied to spinors belonging to the regular and singular sectors of the Lounesto’s classification (Clifford algebras and spinors, Cambridge University Press, Cambridge), looking towards unveil how ...

Spinor Equations of Successor Curves

open access: yesUniversal Journal of Mathematics and Applications, 2022
The aim of this study is to give spinor representation of successive curves in three-dimensional Euclidean space. In three dimensional Euclidean Space, the spinor representations of a curve with unit speed and a successor curve with the same arc length ...

A Mathematical Model for Controlling Exchanged Spinor Waves between Hemoglobin, Tumor and T-Cells

open access: yesMathematics, 2021
To date, it is known that tumor cells respond to attacks of T-cells by producing some PD-1/PD-L1 and other connections. Unfortunately, medical methods for preventing these connections are expensive and sometimes non-effective. In this study, we suggest a

Curvature Spinors in Locally Inertial Frame and the Relations with Sedenion

open access: yesUniverse, 2020
In the 2-spinor formalism, the gravity can be dealt with curvature spinors with four spinor indices. Here we show a new effective method to express the components of curvature spinors in the rank-2 4 × 4 tensor representation for the gravity

Realism, irrationality, and spinor spaces

open access: yesZagadnienia Filozoficzne w Nauce, 2023
Mathematics, as Eugene Wigner noted, is unreasonably effective in physics. The argument of this paper is that the disproportionate attention that philosophers have paid to discrete structures such as the natural numbers, for which a nominalist ...

Six-Dimensional Space with Symmetric Signature and Some Properties of Elementary Particles

open access: yesAxioms, 2022
The six-dimensional pseudo-Euclidean space E3,3 with signature (3,3) is proposed as a model of real physical space at the subparticle scale. The conserved quantum characteristics of elementary particles, such as spin, isospin, electric and baryon charges,
