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

Canonical quantization of macroscopic electromagnetism [PDF]

, 2010
Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption.

The gauge non-invariance of Classical Electromagnetism [PDF]

, 2005
"Physical theories of fundamental significance tend to be gauge theories. These are theories in which the physical system being dealt with is described by more variables than there are physically independent degree of freedom.

Maxwell electromagnetism as an emergent phenomenon in condensed matter

, 2016
The formulation of a complete theory of classical electromagnetism by Maxwell is one of the milestones of science. The capacity of many-body systems to provide emergent mini-universes with vacua quite distinct from the one we inhabit was only recognised ...

Magnetic Oscillations and Maxwell Theory

, 1996
We explore the possibility of using the Kaluza-Klein geometry of Riemannian Submersions to modify the classical Maxwell Theory. We further argue that the resulting modification of Electromagnetism may be interesting in the context of, among other topics,

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

Dynamical laws of superenergy in General Relativity

, 2007
The Bel and Bel-Robinson tensors were introduced nearly fifty years ago in an attempt to generalize to gravitation the energy-momentum tensor of electromagnetism.

Force-Free Gravitational Redshift: Proposed Gravitational Aharonov-Bohm experiment

, 2012
We propose a feasible laboratory interferometry experiment with matter waves in a gravitational potential caused by a pair of artificial field-generating masses. It will demonstrate that the presence of these masses (and, for moving atoms, time dilation)

Seeing the light : experimental signatures of emergent electromagnetism in a quantum spin ice

, 2012
The "spin ice" state found in the rare earth pyrochlore magnets Ho2Ti2O7 and Dy2Ti2O7 offers a beautiful realisation of classical magnetostatics, complete with magnetic monopole excitations.

Galilean Covariance versus Gauge Invariance [PDF]

, 2009
We demonstrate for the first time and unexpectedly that the Principle of Relativity dictates the choice of the "gauge conditions" in the canonical example of a Gauge Theory namely Classical Electromagnetism.
