Discovery of an Intrinsic Antiferromagnetic Semiconductor EuSc2Te4 With Magnetism‐Driven Nonlinear Transport

Advanced Functional Materials, EarlyView.
EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Correlated Electric and Magnetic Dipole Moment in Natural Supersymmetry [PDF]

arXiv, 2019
In the context of supersymmetry, the two-loop Barr-Zee diagrams which induce CP-violating electric dipole moment of electron due to superpartners simultaneously yield CP-conserving magnetic dipole moment of muon. In this paper, we derive the coherence between the electric and magnetic dipole moments at two-loop level due to stops, charginos or ...

Turning on Selective H2S Gas Sensing Activity in Ternary Nickel Tungstate Strongly Correlated Electron System Through Sub‐Gap Band Manipulation

Advanced Functional Materials, EarlyView.
A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

Gravitationally induced electromagnetism at the Compton scale

, 2006
It is shown that Einstein gravity tends to modify the electric and magnetic fields appreciably at distances of the order of the Compton wavelength. At that distance the gravitational field becomes spin dominated rather than mass dominated.

Magnetic signatures of a creosote oil contaminated site: case study in São Paulo, Brazil

Scientific Reports, 2022
Soils and groundwater contamination modifies the physical–chemical conditions of the environment, altering natural biogeochemical processes of the ground. As a result, several mineral transformations occur, in which iron plays a decisive role.

Noncommutative electrodynamics from $$SO(2,3)_\star $$ SO(2,3)⋆ model of noncommutative gravity

European Physical Journal C: Particles and Fields, 2018
In our previous work we have constructed a model of noncommutative (NC) gravity based on $$SO(2,3)_\star $$ SO(2,3)⋆ gauge symmetry. In this paper we extend the model by adding matter fields: fermions and a U(1) gauge field.

Neutrino masses and magnetic moments of electron and muon in the Zee Model

Journal of High Energy Physics, 2022
We explore parameter space in the Zee Model to resolve the long-standing tension of the electron and muon anomalous magnetic moment (AMM). The model comprises a second Higgs doublet and a charged singlet at electroweak scale and generates Majorana ...

A New Approach to Compute the Dipole Moments of a Dirac Electron [PDF]

arXiv, 2019
We present an approach to compute the electric and magnetic dipole moments of an electron by using polarization and magnetization parts of the Dirac current. We show that these dipole moment expressions obtained by our approach in this study are in agreement with the current experimental results in the literature. Also, we observe that a magnetic field
