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…

Vibrational coherences in half-broadband 2D electronic spectroscopy: spectral filtering to identify excited state displacements

Dale Green, Giovanni Bressan, Ismael A. Heisler +2

Vibrational coherences in ultrafast pump-probe (PP) and 2D electronic spectroscopy (2DES) provide insight into the excited state dynamics of molecules. Femtosecond coherence spectr…

Topological-charge-dependent dichroism and birefringence of optical vortices

Kayn A. Forbes, Dale Green

Material anisotropy and chirality produce polarization-dependent light-matter interactions. Absorption leads to linear and circular dichroism, whereas elastic forward scattering pr…

Customized optical chirality of vortex structured light through state and degree of polarization control

Kayn A. Forbes, Dale Green

We show how both the ellipticity and degree of polarization influences the extraordinary optical chirality properties of non-paraxial vortex beams. We find that, i…

Phonon Signatures in Photon Correlations

Ben S. Humphries, Dale Green, Magnus O. Borgh +1

We show that the second-order, two-time correlation functions for phonons and photons emitted from a vibronic molecule in a thermal bath result in bunching and anti-bunching (a pur…

Enantioselective optical gradient forces using 3D structured vortex light

Kayn A Forbes, Dale Green

Here we highlight enantioselective optical gradient forces present in 3D structured optical vortex tweezing systems. One chiral force originates from the circular polarization of t…

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…
