Probing the large-scale magnetic field inside the Sun from three decades of observed surface magnetograms
Space-weather and disturbances in the heliosphere are manifestations of the solar magnetic field, which is solely driven by the interior dynamo, and constraining the solar interior magnetic field and its oscillatory behavior is one of the major challenges in solar physics. Observationally, none of the techniques, including helioseismology, are able to provide an estimation of the interior magnetic field. We reconstruct, for the first time, the dynamics of the interior large-scale magnetic field…

Magnetic Helicity, Magnetic Monopoles, and Higgs Winding
Changes in magnetic helicity are often discussed across a variety of fields, from condensed matter physics to early universe cosmology. It is frequently stated that the helicity change is given by the integral of the gauge field strength tensor and its dual over spacetime, $\int F \wedge F$. However, this is incorrect when magnetic monopoles once exist in the spacetime. In this paper, we show the correct formula of the helicity change in such a case for the Maxwell theory with the magnetic …

High-Precision Temperature Estimation Based on Magnetic Nanoparticles Dominated by Brownian Relaxation under Combined AC and DC Magnetic Fields
Brownian relaxation is one of the primary mechanisms that allows magnetic nanoparticles (MNPs) to convert magnetic energy into thermal energy under an excitation magnetic field. Accurately characterizing the MNPs' magnetization dynamics dominated by Brownian relaxation is crucial for achieving high-precision temperature estimation. However, the lack of a readily applicable analytical expression remains a major obstacle to the advancement of magnetic nanoparticle hyperthermia (MNPH). In this pap…

Stacking-Controlled Magnetic Exchange and Magnetoelectric Coupling in Bilayer CrI$_2$
We use a first-principles calculations approach to reveal the electronic and magnetic properties of chromium diiodide (CrI$_2$) bilayers and establish a hierarchy of magnetic interactions across stable registries. The monolayer presents a x-stripe antiferromagnetic ground state, while in bilayers the BA$^\prime$ stacking is the global minimum with antiparallel interlayer magnetic alignment. Bilayer configurations strengthen the exchange in the plane by 6 % to 10 %, while the exchange between la…

"The government is not raising enough in tax. Most people, understandably, want a level of public services comparable to our neighbours in Western Europe. The amount of taxes we collectively pay, however, is significantly below most countries in Western Europe. ..[It's] a consequence of 14 years of Conservative government."

Magnetoelectric Switching of Competing Magnetic Orders in Rhombohedral Graphene
A finite Hall conductance under zero magnetic field implies time reversal symmetry (TRS) breaking due to magnetic ordering. In rhombohedral (RH) stacked graphene, the angular momentum breaking TRS can result from the orbital degree of freedom at the $K$ and $K'$ valleys. This leads to valley polarization and occupation-dependent anomalous Hall resistance (AHR) due to the chirality in Berry curvature between the valleys. We report magnetoelectric control of orbital magnetic order in crystalline …

Revisiting constraints on magnetogenesis from baryon asymmetry
Magnetic fields in the universe potentially serve as a messenger of primordial physics. The observationally suggested intergalactic magnetic fields may be a relic of helical primordial $\mathrm{U}(1)_Y$ magnetic fields, which may also explain the origin of the baryon asymmetry of the universe. This scenario has been considered to be not viable, which we revisit as well as the baryon isocurvature problem for non-helical primordial $\mathrm{U}(1)_Y$ magnetic fields, based on the recent discussion…
