Failures of the classical optical theorem under arbitrary-shaped beam incidence in electromagnetism, acoustics, and quantum mechanics: motivation and a review

Frontiers in Physics, 2023
The classical optical theorem states that for a wave propagating in a lossless medium and incident on a finite scatterer, the extinction cross section is proportional to the real part of the scattering amplitude in the forward direction.

Spinning gauged boson and Dirac stars: A comparative study

Physics Letters B, 2022
Scalar boson stars and Dirac stars are solitonic solutions of the Einstein–Klein-Gordon and Einstein-Dirac classical equations, respectively. Despite the different bosonic vs.

Nonseparability, Classical and Quantum [PDF]

, 2010
This paper examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretation evinces a form of nonseparability, something that ...

Forces between electric charges in motion: Rutherford scattering, circular Keplerian orbits, action-at-a-distance and Newton's third law in relativistic classical electrodynamics

, 2007
Standard formulae of classical electromagnetism for the forces between electric charges in motion derived from retarded potentials are compared with those obtained from a recently developed relativistic classical electrodynamic theory with an ...

The classical geometrization of the electromagnetism [PDF]

, 2014
Following the line of the history, if by one side the electromagnetic theory was consolidated on the 19th century, the emergence of the special and the general relativity theories on the 20th century opened possibilities of further developments, with the

Time reversal in classical electromagnetism [PDF]

, 2007
Richard Feynman has claimed that anti-particles are nothing but particles `propagating backwards in time'; that time reversing a particle state always turns it into the corresponding anti-particle state. According to standard quantum eld theory textbooks

Elastic‐Wave Propagation in Chiral Metamaterials: A Couple‐Stress Theory Perspective

Advanced Engineering Materials, EarlyView.
The intrinsic chirality of chiral metamaterials renders an effective medium based on the classical continuum theory ineffective for predicting their acoustic activity. This limitation is addressed in the present study by employing augmented asymptotic homogenization to derive a couple‐stress‐based effective medium, enabling accurate predictions in the ...
