Reduced-order Abraham-Lorentz-Dirac equation and the consistency of classical electromagnetism [PDF]
, 2014 It is widely believed that classical electromagnetism is either unphysical or inconsistent, owing to pathological behavior when self-force and radiation reaction are non-negligible. We argue that there is no inconsistency as long as it is recognized that

Current-induced magnetization caused by crystal chirality in nonmagnetic elemental tellurium
Physical Review Research, 2021 Chiral matter has a structure that lacks inversion, mirror, and rotoreflection symmetry; thus, a given chiral material has either a right- or left-handed structure. In chiral matter, electricity and magnetism can be coupled in an exotic manner beyond the

IEEE Antennas & Propagation Magazine, 2020 This article explores some dominant trends in teaching classical electromagnetic (EM) field theory in electrical engineering (EE) undergraduate curricula. The acronym EM will be used interchangeably to designate either electromagnetic or electromagnetism.

Classical limit of higher-spin string amplitudes
Journal of High Energy Physics, 2023 It has been shown that a special set of three-point amplitudes between two massive spinning states and a graviton reproduces the linearised stress-energy tensor for a Kerr black hole in the classical limit. In this work we revisit this result and compare

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection
Journal of High Energy Physics, 2023 The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations.

Advanced Materials Interfaces, EarlyView., 2023 This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

Electromagnetism in terms of quantum measurements [PDF]
, 2015 We consider the question whether electromagnetism can be derived from quantum physics of measurements. It turns out that this is possible, both for quantum and classical electromagnetism, if we use more recent innovations such as smearing of observables ...

Dimensional reduction of electromagnetism [PDF]
Journal of Mathematics and Physics, 2021 We derive one- and two-dimensional models for classical electromagnetism by making use of Hadamard's method of descent. Low-dimensional electromagnetism is conceived as a specialization of the higher dimensional one, in which the fields are uniform along

Classical analog of electromagnetically induced transparency [PDF]
American Journal of Physics, 2002 We present a classical analog of electromagnetically induced transparency (EIT). In a system of just two coupled harmonic oscillators subject to a harmonic driving force, we reproduce the phenomenology observed in EIT. We also describe a simple experiment with two linearly coupled RLC circuits which can be incorporated into an undergraduate laboratory.

Nonlinear extensions of gravitating dyons: from NUT wormholes to Taub-Bolt instantons
Journal of High Energy Physics, 2021 Recent work has shown the existence of a unique nonlinear extension of electromagnetism which preserves conformal symmetry and allows for the freedom of duality rotations.
