A General DoF and Pattern Analyzing Scheme for Electromagnetic Information Theory

IEEE Transactions on Information Theory
Electromagnetic information theory (EIT) is one of the emerging topics for 6G communication due to its potential to reveal the performance limit of wireless communication systems. For EIT, one of the most important research directions is degree of freedom (DoF) analysis. Existing research works on DoF analysis for EIT focus on asymptotic conclusions of

Comparison of electromagnetic performance in MW class superconducting machines according to shielding and structures based on analytical method

AIP Advances
This paper presents an analytical method for analyzing the electromagnetic performance of a superconducting (SC) machine according to the 10 MW shielding configuration and the presence or absence of an armature core.

Ladder symmetries and Love numbers of Reissner-Nordström black holes

Journal of High Energy Physics
It is well known that asymptotically flat black holes in general relativity have vanishing tidal Love numbers. In the case of Schwarzschild and Kerr black holes, this property has been shown to be a consequence of a hidden structure of ladder symmetries ...

Probing effective field theory corrections with quasinormal modes and gravitational lensing in Reissner–Nordström black holes

European Physical Journal C: Particles and Fields
Effective field theory (EFT) provides a systematic framework for parametrizing possible higher-energy corrections to general relativity through higher-curvature interactions.

Simple circuit and experimental proposal for the detection of gauge-waves

Journal of Physics Communications
Aharonov-Bohm electrodynamics predicts the existence of traveling waves of pure potentials, with zero electromagnetic fields, denoted as gauge waves, or g-waves for short.
