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.

Effective field theory interpretation of lepton magnetic and electric dipole moments [PDF]
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 ...

Oriented Polar Molecules in a Solid Inert-Gas Matrix: A Proposed Method for Measuring the Electric Dipole Moment of the Electron [PDF]
Atoms, 2018 We propose a very sensitive method for measuring the electric dipole moment of the electron using polar molecules embedded in a cryogenic solid matrix of inert-gas atoms.

Constraining
Physical Review D, 2015 We analyse some dimension-five CPT-even and Lorentz-violating nonminimal couplings between fermionic and gauge fields in the context of the Dirac equation. After evaluating the nonrelativistic Hamiltonian, we discuss the behavior of the terms under discrete symmetries and analyse the implied effects. We then use the anomalous magnetic dipole moment and

The shadow of dark matter as a shadow of string theory
European Physical Journal C: Particles and Fields, 2019 We point out that string theory can solve the conundrum to explain the emergence of an electroweak dipole moment from electroweak singlets through induction of those dipole moments through a Kalb–Ramond dipole coupling.

Numerical evaluation of systematics in the experiment for electron electric dipole moment measurement in HfF+ [PDF]
Physical Review A, 2023 Hyperfine structure of the ground rotational level of the metastable $^3\Delta_1$ electronic state of $^{180}$HfF$^+$ ion is calculated at presence of variable external electric and magnetic fields.

Electron and muon anomalous magnetic dipole moment in the 3-3-1 model with heavy leptons
, 2018 Nós calculamos, no contexto do modelo 3-3-1 com léptons pesados carregados, vínculos sobre alguns dos parâmetros das partículas extras do modelo ao impor que suas contribuições aos fatores (g-2) do elétron e do múon estejam de acordo com os dados experimentais dentro de 1 sigma - 3 sigma.

Muon anomalous magnetic dipole moment in the μ νSSM [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2021 Recently, the Muon g-2 experiment at Fermilab measured the muon anomalous magnetic dipole moment (MDM), , and reported that the new experimental average increases the difference between the experiment and the standard model (SM) prediction to 4.2σ.

Methods for measuring the electron’s electric dipole moment using ultracold YbF molecules [PDF]
Quantum Science and Technology, 2020 Measurements of the electron’s electric dipole moment (eEDM) are demanding tests of physics beyond the standard model. We describe how ultracold YbF molecules could be used to improve the precision of eEDM measurements by two to three orders of magnitude.
