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).

Optical cycling and sensitivity to the electron's electric dipole moment in gold-containing molecules [PDF]

Physical Review A
We propose diatomic molecules built from gold and carbon-group atoms as promising candidates for optical cycling and precision measurements. We show that this class of molecules (AuX, X = C, Si, Ge, Sn, Pb) features laser-accessible electronic ...

Magnetic and electric dipole moments of the $H\ {}^3\Delta_1$ state in ThO [PDF]

, 2011
The metastable $H \ {}^3\Delta_1$ state in the thorium monoxide (ThO) molecule is highly sensitive to the presence of a CP-violating permanent electric dipole moment of the electron (eEDM).

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 ...

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

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.

Laser-cooled HgF as a promising candidate to measure the electric dipole moment of the electron [PDF]

Physical Review A, 2018
In order to realize more sensitive eEDM measurement, it would be worthwhile to find some new laser-cooled molecules with larger internal effective electric field (E$_{eff}$), higher electric polarizability and longer lifetime of the eEDM measurement ...
