Iterant Algebra

open access: yesEntropy, 2017
We give an exposition of iterant algebra, a generalization of matrix algebra that is motivated by the structure of measurement for discrete processes. We show how Clifford algebras and matrix algebras arise naturally from iterants, and we then use this ...

Dirac geometry II: coherent cohomology

open access: yesForum of Mathematics, Sigma
Dirac rings are commutative algebras in the symmetric monoidal category of $\mathbb {Z}$ -graded abelian groups with the Koszul sign in the symmetry isomorphism.

Particle dynamics and Lie-algebraic type of non-commutativity of space–time

open access: yesNuclear Physics B, 2018
In this paper, we present the results of our investigation relating particle dynamics and non-commutativity of space–time by using Dirac's constraint analysis.

New canonical analysis for higher order topologically massive gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
A detailed Gitman–Lyakhovich–Tyutin analysis for higher-order topologically massive gravity is performed. The full structure of the constraints, the counting of physical degrees of freedom, and the Dirac algebra among the constraints are reported ...

The Dirac equation in an external electromagnetic field: symmetry algebra and exact integration [PDF]

open access: yes, 2015
Integration of the Dirac equation with an external electromagnetic field is explored in the framework of the method of separation of variables and of the method of noncommutative integration. We have found a new type of solutions that are not obtained by

Some statistical aspects of the spinor field Fermi-Bose duality

open access: yesCondensed Matter Physics, 2012
The structure of 29-dimensional extended real Clifford-Dirac algebra, which has been introduced in our paper Phys. Lett. A, 2011, Vol. 375, 2479, is considered in brief.

Catalytic Electron‐Driven Non‐Equilibrium Phase Transition in Quantum Electronic Heterostructures

open access: yesAdvanced Science, EarlyView.
This study proposes an innovative method to control the phase of heterostructured materials via electron flow manipulation. Leveraging this technique, a new topological phase is achieved that hosts excitons at the interface of a topological insulator.

The space of Dunkl monogenics associated with Z23

open access: yesNuclear Physics B, 2022
The universal Bannai–Ito algebra BI is a unital associative algebra over C generated by X,Y,Z and the relations assert that each of{X,Y}−Z,{Y,Z}−X,{Z,X}−Y commutes with X,Y,Z. Let n≥0 denote an integer.

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift

open access: yesAnnalen der Physik, EarlyView.
The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

Dirac algebra formalism for Two Higgs Doublet Models: The one-loop effective potential

open access: yesPhysics Letters B
We present a novel covariant bilinear formalism for the Two Higgs Doublet Model (2HDM) which utilises the Dirac algebra associated with the SL(2,C) group that acts on the scalar doublet field space.
