Noncommutative QED and Anomalous Dipole Moments [PDF]

, 2000
We study QED on noncommutative spaces, NCQED. In particular we present the detailed calculation for the noncommutative electron-photon vertex and show that the Ward identity is satisfied.

Optical Activity of Spin‐Forbidden Electronic Transitions in Metal Complexes from Time‐Dependent Density Functional Theory with Spin‐Orbit Coupling

ChemistryOpen, 2022
The calculation of magnetic transition dipole moments and rotatory strengths was implemented at the zeroth‐order regular approximation (ZORA) two‐component relativistic time‐dependent density functional theory (TDDFT) level. The circular dichroism of the

Antiferro quadrupolar ordering in Fe intercalated few layers graphene

AIP Advances, 2013
The π electron cloud above and below the honeycomb structure of graphene causes each carbon atom to carry a permanent electric quadrupole moment which can attach any cation to impart interesting physical properties.

Nondestructive Measurement of Orbital Angular Momentum for an Electron Beam [PDF]

, 2016
Free electrons with a helical phase front, referred to as "twisted" electrons, possess an orbital angular momentum (OAM) and, hence, a quantized magnetic dipole moment along their propagation direction. This intrinsic magnetic moment can be used to probe

About a peculiar U(1): Z' discovery limit, muon anomalous magnetic moment and electron electric dipole moment [PDF]

Physical Review D, 2008
The model (Lagrangian) with a peculiar extra U(1)is clearly presented. The assigned extra U(1) gauge charges give a strong constraint to build Lagrangians. The Z' discovery limits are estimated and predicted at the Tevatron and the LHC. The new contributions of the muon anomalous magnetic moment are investigated at one and two loops, and we predict ...

Spin–Orbit and Zeeman Effects on the Electronic Properties of Single Quantum Rings: Applied Magnetic Field and Topological Defects

Nanomaterials, 2023
Within the framework of effective mass theory, we investigate the effects of spin–orbit interaction (SOI) and Zeeman splitting on the electronic properties of an electron confined in GaAs single quantum rings.

2D Spin-Dependent Diffraction of Electrons From Periodical Chains of Nanomagnets

Applied Sciences, 2012
The scattering of the unpolarized beams of electrons by nanomagnets in the vicinity of some scattering angles leads to complete spin polarized electrons. This result is obtained with the help of the perturbation theory.

Inelastic transverse magnetic dipole electron scattering form factors in 48Ca (restricted optimum configurations)

Iraqi Journal of Physics, 2019
Inelastic transverse magnetic dipole electron scattering form factors in 48Ca have been investigated through nuclear shell model in an excited state energy Ex= 10.23 MeV which is so called "mystery case" with different optional choices like effective ...

A comparison of methods to measure the magnetic moment of magnetotactic bacteria through analysis of their trajectories in external magnetic fields.

PLoS ONE, 2013
Magnetotactic bacteria possess organelles called magnetosomes that confer a magnetic moment on the cells, resulting in their partial alignment with external magnetic fields.
