Transversality Locks Longitudinal Gradients in Structured-Light Quadrupole Transitions
Kayn A. Forbes, Dale Green, Abdullah F. Alharbi +1
Electric quadrupole absorption is driven by optical field gradients, not by field amplitudes alone. This distinction is crucial for structured light, where a paraxially small longi…

Indirect Communication Between Non-Markovian Baths
Ben S. Humphries, Dale Green, Garth A. Jones
In this work we develop a model for an undamped vibration in the presence of an overdamped bath. This two-bath model involves a new derivation of the hierarchical equations of moti…

Relevance of Longitudinal Fields of Paraxial Optical Vortices
Kayn A. Forbes, Dale Green, Garth A. Jones
Longitudinal electromagnetic fields generally become comparable with the usually dominant transverse components in strongly-focussed, non-paraxial beams. For optical vortex modes i…
