Multiplicative Dirac System

Kuwait Journal of Science, 2022
We define a Dirac system in multiplicative calculus by some algebraic structures. Asymptotic estimates for eigenfunctions of the multiplicative Dirac system are obtained.

A multi-component super integrable Dirac hierarchy

Physics Letters B, 2023
We propose a method for generating higher-dimensional nonisospectral super integrable coupling hierarchies associated with a new type of higher-dimensional Lie superalgebra.

Dirac–Nijenhuis structures [PDF]

Journal of Physics A: Mathematical and General, 2004
Summary: In this paper, we study the concept of Dirac-Nijenhuis structures. We consider them to be a pair \((D,{\mathcal N})\) where \(D\) is a Dirac structure, defined with respect to a Lie bialgebroid \((A,A^\ast )\), and \({\mathcal N}\) is a Nijenhuis operator which defines a deformation of the Lie algebroid structure of \(D\) in a compatible way ...

Computational Prediction of New Series of Topological Ternary Compounds LaXS (X = Si, Ge, Sn) from First-Principles

J, 2021
Dirac materials and their advanced physical properties are one of the most active fields of topological matter. In this paper, we present an ab initio study of electronics properties of newly designed LaXS (X = Si, Ge, Sn) tetragonal structured ternaries,

Theoretical Model for a Novel Electronic State in a Dirac Electron System Close to Merging: An Imaginary Element between Sulphur and Selenium

Crystals, 2022
Topological materials with Dirac electron systems have been extensively studied. Organic crystalline materials form a unique group of such compounds with well-defined crystal structures.

Epitaxy and transport properties of alkali-earth palladate thin films

Science and Technology of Advanced Materials, 2023
Topological insulators and semimetals are an interesting class of materials for new electronic and optical applications owing to their characteristic electromagnetic responses originating from the spin-orbit coupled band structures.

Quasi-exact solutions for guided modes in two-dimensional materials with tilted Dirac cones

Scientific Reports, 2022
We show that if the solutions to the (2+1)-dimensional massless Dirac equation for a given one-dimensional (1D) potential are known, then they can be used to obtain the eigenvalues and eigenfunctions for the same potential, orientated at an arbitrary ...
