A Conformally Invariant Derivation of Average Electromagnetic Helicity
The results are shown to be equivalent to the well-known volume integral for the average helicity, featuring the electric and magnetic fields and potentials.

We study the question of whether a helicity-transporting current is generated in a rotating photon gas at finite temperature. One problem is that there is no gauge-invariant local notion of helicity…

Duality Symmetry of Quantum Electrodynamics and Magnetic Charges
The duality symmetry between electricity and magnetism hidden in classical Maxwell equations suggests the existence of dual charges, which have usually been interpreted as magnetic charges and have…
Transverse spin dynamics in structured electromagnetic guided waves
- PhysicsProceedings of the National Academy of Sciences
A set of spin–momentum equations are derived which describes the relationship between the spin and orbital properties of arbitrary complex electromagnetic guided modes and open up opportunities for designing the spin structure and topological properties of electromagnetic waves.
Optical momentum and angular momentum in complex media: From the Abraham-Minkowski debate to unusual properties of surface plasmon-polaritons
We examine the momentum and angular-momentum (AM) properties of monochromatic optical fields in dispersive and inhomogeneous isotropic media, using the Abraham- and Minkowski-type approaches, as well…

Transverse spin dynamics of light: the generalized spin-momentum locking for structured guided modes

Dual-symmetric Lagrangians in quantum electrodynamics: I. Conservation laws and multi-polar coupling
By using a complex field with a symmetric combination of electric and magnetic fields, a first-order covariant Lagrangian for Maxwell's equations is obtained, similar to the Lagrangian for the Dirac…
Electromagnetic Duality Anomaly in Curved Spacetimes.
- PhysicsPhysical review letters
It is shown that this conservation law is broken at the quantum level in the presence of a background classical gravitational field with a nontrivial Chern-Pontryagin invariant, in parallel with the chiral anomaly for massless Dirac fermions.
Electromagnetic duality symmetry and helicity conservation for the macroscopic Maxwell's equations.
- PhysicsPhysical review letters
It is shown that the electromagnetic duality symmetry can be restored for the macroscopic Maxwell's equations by the presence of charges, and the restoration is shown to be independent of the geometry of the problem.
The role of the Riemann–Silberstein vector in classical and quantum theories of electromagnetism
It is shown that the use of the Riemann–Silberstein (RS) vector greatly simplifies the description of the electromagnetic field both in the classical domain and in the quantum domain. In this review,…

Dual electromagnetism: Helicity, spin, momentum, and angular momentum
The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity and, as we…
