Time diffraction of optical helicity
Alex J. Vernon, Jingyi Wu, Anton Y. Bykov +4
If in a classic double-slit interference experiment the light that passes though one slit is in an orthogonal polarisation state to that of the second slit, no visible interference…
Dipole light-matter interactions in the bispinor formalism
Sebastian Golat, Alex J. Vernon, Francisco J. Rodríguez-Fortuño
The conventional formulation of power absorption, optical forces, and torques on dipolar particles involve lenghty and cumbersome expressions that obscure their shared physical ori…
Electric-Magnetic Geometric Phase
Alex J. Vernon, Konstantin Y. Bliokh
Geometric phases play an enormous role in optics and are generally associated with the evolution of light's polarization state on the Poincaré sphere, or its spin on the sphere of…
Topologies of light in electric-magnetic space
Alex J. Vernon
In nonparaxial, monochromatic light the electric and magnetic fields generally have different energy densities, different singularities and different polarisation structures. A top…
