Relativistic Mechanics

open access: yes, 2005
Abstract It was apparent from its beginning that special relativity developed as the invariance theory of electrodynamics would require a modification of Newton’s three laws of motion. This chapter discusses that modified theory. The relativistically modified mechanics is presented and then recast into a fourvector form that demonstrates

q-Deformed Relativistic Fermion Scattering

open access: yesAdvances in High Energy Physics, 2017
In this article, after introducing a kind of q-deformation in quantum mechanics, first, q-deformed form of Dirac equation in relativistic quantum mechanics is derived. Then, three important scattering problems in physics are studied.

Approximation of Dirac operators with δ‐shell potentials in the norm resolvent sense, II: Quantitative results

open access: yesMathematische Nachrichten, EarlyView.
Abstract This paper is devoted to the approximation of two‐ and three‐dimensional Dirac operators HV∼δΣ$H_{\widetilde{V} \delta _\Sigma }$ with combinations of electrostatic and Lorentz scalar δ$\delta$‐shell interactions in the norm resolvent sense. Relying on results from Behrndt, Holzmann, and Stelzer‐Landauer [Math. Nachr.

Fisher Information and Electromagnetic Interacting Dirac Spinors

open access: yesAxioms
In earlier works, it was demonstrated that Schrödinger’s equation, which includes interactions with electromagnetic fields, can be derived from a fluid dynamic Lagrangian framework.

Surface‐Embedded Ag@Multilayer Graphene for Photothermal‐Enhanced Superhydrophobic Anti‐Icing Coatings

open access: yesRare Metals, EarlyView.
ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

Relativistic waves are required for the Planck spectrum in classical physics

open access: yesJournal of Physics Communications
A derivation of the Planck spectrum is given based upon the fluctuations of relativistic waves, waves moving with speed c in a relativistic spacetime.

Time in Quantum Mechanics and the Local Non-Conservation of the Probability Current

open access: yesMathematics, 2018
In relativistic quantum field theory with local interactions, charge is locally conserved. This implies local conservation of probability for the Dirac and Klein–Gordon wavefunctions, as special cases; and in turn for non-relativistic quantum field

Enhancing the Chemical Reactivity of Graphene through Substrate Engineering

open access: yesSmall, EarlyView.
This review highlights methods to enhance the reactivity of graphene through substrate engineering, focusing on strain and charge doping. Strains induced by nanoparticles, metal crystal orientations, or stretchable polymers increase the reactivity of graphene.

Obtaining the non-relativistic quantum mechanics from quantum field theory: issues, folklores and facts

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Given the classical dynamics of a non-relativistic particle in terms of a Hamiltonian or an action, it is relatively straightforward to obtain the non-relativistic quantum mechanics (NRQM) of the system.

Influence of the Chemical Composition on the Perovskites Anharmonicity: Toward a Stable Inorganic Perovskite

open access: yesSolar RRL, EarlyView.
This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...
