Comment on the paper by Rovelli & al. about the compatibility of various "gauge conditions" [PDF]
, 2007 The compatibility "demonstrated" by Rovelli & al. between various "gauge conditions" both in Classical Electromagnetism and General Relativity can be better understood if one distinguishes "gauge conditions" of the solution type and "gauge conditions" of

Classical observables using exponentiated spin factors: electromagnetic scattering
Journal of High Energy PhysicsIn [1], the authors argued that the Newman-Janis algorithm on the space of classical solutions in general relativity and electromagnetism could be used in the space of scattering amplitudes to map an amplitude with external scalar states to an amplitude ...

Gravitation and Electromagnetism
, 2016 The realms of gravitation, belonging to Classical Physics, and Electromagnetism, belonging to the Theory of the Electron and Quantum Mechanics have remained apart as two separate pillars, inspite of a century of effort by Physicists to reconcile them. In

On the completeness of classical electromagnetism
, 2006 The possibility of an incompletness of the equations of electromagnetism is analyzed using a thought experiment that shows a non-physical behavior according to classical electromagnetism. Basically, from Maxwell equations it is shown that a particular passive, isolated circuit could present a transient growth of its currents. Resolution of this problem

Pauli–Villars regularization elucidated in Bopp–Podolsky’s generalized electrodynamics
European Physical Journal C: Particles and Fields, 2019 We discuss an inherent Pauli–Villars regularization in Bopp–Podolsky’s generalized electrodynamics. Introducing gauge-fixing terms for Bopp–Podolsky’s generalized electrodynamic action, we realize a unique feature for the corresponding photon propagator ...

Shapeshifting Nanocatalyst for CO2 Conversion
Advanced Materials, EarlyView.A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.
