Atomic state interferometry for complex vector light
Kuntal Samanta, Sphinx J. Svensson, Sonja Franke-Arnold +1
Features of complex vector light become important in any interference effects, including scattering, diffraction, and non-linear processes. Here we are investigating the role of po…
Is diamagnetism really acausal?
Niclas Westerberg, Stephen M. Barnett
Diamagnetism, in which the magnetisation in a medium opposes the direction of an applied magnetic field, is a weak but familiar effect in a wide class of materials. Being weak it i…
Is there a conflict between causality and diamagnetism?
Niclas Westerberg, Stephen M. Barnett
There is a long-standing apparent conflict between the existence of diamagnetism and causality as expressed through the Kramers-Kronig relations. In essence, using causality argume…
Quantised helicity in optical media
Neel Mackinnon, Jörg B. Götte, Stephen M. Barnett +1
We present a new approach to the definition of optical helicity in a medium. Our approach resolves the problem that duality transformations which simultaneously combine $\mathbf{E}…
Fluorescence Lifetime Hong-Ou-Mandel Sensing
Ashley Lyons, Vytautas Zickus, Raúl Álvarez-Mendoza +5
Fluorescence Lifetime Imaging Microscopy in the time domain is typically performed by recording the arrival time of photons either by using electronic time tagging or a gated detec…
Duality, decay rates and local-field models in macroscopic QED
Niclas Westerberg, Anette Messinger, Stephen M. Barnett
Any treatment of magnetic interactions between atoms, molecules and optical media must start at the form of the interaction energy. This forms the base on which predictions about a…
