Exciton-induced electric dipole moment in organic ferromagnets

New Journal of Physics, 2023
Based on an Anderson-like model including electron–lattice interaction and electron–electron (e–e) interactions, charge and spin properties of excitons in quasi-one-dimensional organic ferromagnets with spin radicals are investigated.

Magnetic field amplification in electron phase-space holes and related effects [PDF]

Annales Geophysicae, 2012
Three-dimensional electron phase-space holes are shown to have positive charges on the plasma background, which produce a radial electric field and force the trapped electron component into an azimuthal drift.

Effective field theory interpretation of lepton magnetic and electric dipole moments

Journal of High Energy Physics, 2021
We perform a model-independent analysis of the magnetic and electric dipole moments of the muon and electron. We give expressions for the dipole moments in terms of operator coefficients of the low-energy effective field theory (LEFT) and the Standard ...

Lepton flavor violation, lepton (g − 2) μ, e and electron EDM in the modular symmetry

Journal of High Energy Physics, 2022
We study the lepton flavor violation (LFV), the leptonic magnetic moments (g − 2) μ, e and the electric dipole moment (EDM) of the electron in the Standard-Model Effective Field Theory with the Γ N modular flavor symmetry. We employ the stringy Ansatz on

The metastable Q 3Δ2 state of ThO: a new resource for the ACME electron EDM search

New Journal of Physics, 2020
The best upper limit for the electron electric dipole moment was recently set by the ACME collaboration. This experiment measures an electron spin-precession in a cold beam of ThO molecules in their metastable $H\,{(}^{3}{{\rm{\Delta }}}_{1})$ state ...

Quantum chemical insight into the effects of the local electron environment on T2*-based MRI

Scientific Reports, 2021
T2* relaxation is an intrinsic magnetic resonance imaging (MRI) parameter that is sensitive to local magnetic field inhomogeneities created by the deposition of endogenous paramagnetic material (e.g. iron).

Electron electric dipole moment in mirror fermion model with electroweak scale non-sterile right-handed neutrinos

Nuclear Physics B, 2018
The electric dipole moment of the electron is studied in detail in an extended mirror fermion model with the following unique features of (a) right-handed neutrinos are non-sterile and have masses at the electroweak scale, and (b) a horizontal symmetry ...

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

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.

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.
