Monopole-center vortex chains in $SU(2)$ gauge theory

open access: yes, 2016
We study the relation between center vortex fluxes and monopole fluxes for $SU(2)$ gauge group in a model. This model is the same as thick center vortex model but we use monopole-antimonopole configurations instead of center vortices in the vacuum ...

Contribution Quantification to Spring Low‐Level Jets Over the Western Bohai Sea Coast: Insights From Doppler LiDAR Observations, WRF Modeling and EOF Analysis

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Low‐level jets (LLJs), as dynamically significant narrow air currents in the lower troposphere, profoundly influence regional weather and anthropogenic activities. Motivated by persistent LLJs detected through Doppler LiDAR observations during March to April 2021, this study systematically characterizes these LLJs over Juehua Island (western ...

M-Shaped Conformal Antenna with FSS Backing for Gain Enhancement

open access: yesEngineering Proceedings
A frequency selective surface (FSS) integrated conformal antenna is modelled and analytical study is presented in this article. A novel antenna design known as the “M-shaped Conformal Antenna with FSS Backing for Gain Improvement” makes use of both the ...

Phase transition of a charged AdS black hole with a global monopole through geometrical thermodynamics

open access: yesPhysics Letters B, 2020
In order to study the phase transition through thermodynamic geometry, we consider the charged AdS black hole with global monopole. We first introduce thermodynamics of charged AdS black hole with global monopole by discussing the dependence of Hawking ...

Subject grounding to reduce electromagnetic interference for MRI scanners operating in unshielded environments

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1289-1298, February 2026.
Abstract Purpose Portable low‐field (<0.1T) MRI is increasingly used for point‐of‐care imaging, but electromagnetic interference (EMI) presents a significant challenge, especially in unshielded environments. EMI can degrade image quality and compromise diagnostic utility.

Dynamics of Nambu monopole in two Higgs doublet models. Cosmological Monopole Collider

open access: yesJournal of High Energy Physics, 2020
We study the dynamics of the Nambu monopole in two Higgs doublet models, which is a magnetic monopole attached by two topological Z strings (Z flux tubes) from two opposite sides. The monopole is a topologically stable solution of the equation of motions

Temperature Dependence of Extended and Fractional SU(3) Monopole Currents

open access: yes, 1994
We examine in pure SU(3) the dependence of extended monopole current k and cross-species extended monopole current k^{cross} on temperature t, monopole size L, and fractional monopole charge 1/q.

BPS Monopoles

open access: yesInternational Journal of Modern Physics A, 1997
We review classical BPS monopoles, their moduli spaces, twistor descriptions and dynamics. Particular emphasis is placed upon symmetric monopoles, where recent progress has been made. Some remarks on the role of monopoles in S duality and Seiberg–Witten theory are also made.

Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...
