Extra Dirac equations

open access: yesIl Nuovo Cimento B Series 11, 1996
This paper has rather a pedagogical meaning. Surprising symmetries in the $(j,0)\oplus (0,j)$ Lorentz group representation space are analyzed. The aim is to draw reader's attention to the possibility of describing the particle world on the ground of the Dirac "doubles".

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

open access: yesAdvanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Born-infeld electrodynamics: Clifford number and spinor representations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The Clifford number formalism for Maxwell equations is considered. The Clifford imaginary unit for space-time is introduced as coordinate independent form of fully antisymmetric fourth-rank tensor.

Relativistic scattering of fermions in quaternionic quantum mechanics

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this article, we propose a quaternionic version of the Dirac equation in the presence of scalar and vector potentials. It has been shown that in complex limit of such an equation, the complex version of this equation can be covered.

Cooperative Goniopolar and Anomalous Nernst Transverse Thermoelectricity in Kagome Magnets

open access: yesAdvanced Materials, EarlyView.
A cooperative transverse thermoelectric mechanism is realized in kagome magnets, where axis‐dependent goniopolar effects and Berry curvature‐driven anomalous Nernst coexist within the same energy window. In MgMn6Sn6, this intrinsic synergy yields a record room‐temperature transverse thermopower of 15.6 µV K−1, establishing a general strategy for high ...

Controlled Synthesis of Tri‐ and Multi‐Doped Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This review systematically evaluates synthesis routes for tri‐ and multi‐doped graphene, from hydrothermal and pyrolysis methods to flash Joule heating, critically assessing how each governs dopant incorporation, bonding configuration, and resulting electronic properties.

On the 2D Dirac oscillator in the presence of vector and scalar potentials in the cosmic string spacetime in the context of spin and pseudospin symmetries

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The Dirac equation with both scalar and vector couplings describing the dynamics of a two-dimensional Dirac oscillator in the cosmic string spacetime is considered.

Type‐II Dirac Fermions in Monolayer In2O: Interplay of Magnetotransport, Spin Hall Effect, and Superconductivity

open access: yesAdvanced Science, EarlyView.
First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Isotropic Dirac fermion and anomalous oscillator strength of the zeroth Landau level transition in LaAlSi

open access: yesCommunications Physics
Dirac fermions, with linear dispersion and relativistic nature, are a prominent class of quasiparticles in condensed matter physics. While the Dirac equation provides a remarkable framework for describing these quasiparticles, symmetry constraints in ...
