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…
Chiral forces in longitudinally invariant dielectric photonic waveguides
Josep Martínez-Romeu, Iago Díez, Sebastian Golat +2
Optical forces can be chiral when they exhibit opposite signs for the two enantiomeric versions of a chiral molecule or particle. Such forces could be eventually used to separate e…
A decomposition of light's spin angular momentum density
Alex J. Vernon, Sebastian Golat, Claire Rigouzzo +2
Light carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light's SAM…
Optical chiral sorting forces and their manifestation in evanescent waves and nanofibres
Sebastian Golat, Jack J. Kingsley-Smith, Iago Diez +3
Optical fields can exert forces of chiral nature on molecules and nanoparticles, which would prove extremely valuable in the separation of enantiomers with pharmaceutical applicati…
Complex refraction metasurfaces for locally enhanced propagation through opaque media
Sinuhé Perea-Puente, Francisco J. Rodríguez-Fortuño
Metasurfaces with linear phase gradients can redirect light beams. We propose controlling both phase and amplitude of a metasurface to extend Snell's law to the realm of complex an…
Non-Diffracting Polarisation Features around Far-Field Zeros of Electromagnetic Radiation
Alex J. Vernon, Andrew Kille, Francisco J. Rodríguez-Fortuño +1
Light from any physical source diffracts over space, as spherical wavefronts grow and energy density is spread out. Diffractive effects pose fundamental limits to light-based techn…
