Published in 2024 at "Journal of High Energy Physics"

DOI: 10.1007/jhep11(2024)075

Abstract: The kinetic mixing of two U(1) gauge theories can result in a massless photon that has perturbative couplings to both electric and magnetic charges. This framework can be used to perturbatively calculate in a quantum… read more here.

Published in 2017 at "AIP Advances"

DOI: 10.1063/1.4974016

Abstract: We developed a two-dimensional imaging method for weak magnetic charge distribution using a commercially available magnetic impedance sensor whose magnetic field resolution is 10 pT/Hz1/2 at 10 Hz. When we applied the vibrating sample magnetometry,… read more here.

Published in 2024 at "Journal of Cosmology and Astroparticle Physics"

DOI: 10.1088/1475-7516/2024/05/128

Abstract: We present a novel mechanism for producing topologically stable monopoles (TSMs) from the quantum mechanical decay of metastable cosmic strings in the early universe. In an SO(10) model this mechanism yields TSMs that carry two… read more here.

Published in 2022 at "Physical Review D"

DOI: 10.1103/physrevd.105.023024

Abstract: The feature of the observed shadows and rings of an astrophysical black hole (BH) may depend on its accretion flows and magnetic charge. We find that the shadow radii and critical impact parameters of the… read more here.

Published in 2025 at "Modern Physics Letters A"

DOI: 10.1142/s0217732325500051

Abstract: In this study, we investigate the shadow of dynamic Phantom black hole (BH) and their observable implications with actual images of the BHs M87* and SgrA. Using the Hamilton–Jacobi formalism, we derive the null geodesic… read more here.

Published in 2022 at "Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science"

DOI: 10.1177/09544062221110766

Abstract: Permanent magnets (PMs) are widely used in magnetic machinery. To better predict the performance of PMs, the magnetic field and force need to be calculated. In general applications, PMs are usually magnetized in a direction… read more here.

Published in 2025 at "Energies"

DOI: 10.3390/en18133520

Abstract: Axial flux motors have attracted significant attention in recent years due to their advantages such as shorter axial length and high torque density. However, the optimization of axial flux motors is an extremely time-consuming process.… read more here.
