Absolute measurement of the intrinsic helicity in nanophotonics
Malo Bézard, Simon Garrigou, Jérémie Béal +5
Helicity is a universal quantity describing the internal rotation of an object or a field. Whether it characterizes fundamental properties such as the spin of elementary particles…
Atomic-like selection rules in free electron scattering
Simon Garrigou, Hugo Lourenço-Martins
Phase-shaped electron energy-loss spectroscopy (PSEELS) measures the scattering probability of structured free electron beams by a target. Over the last decade, it was shown that t…
Attosecond electron microscopy by free-electron homodyne detection
John H. Gaida, Hugo Lourenço-Martins, Murat Sivis +4
Time-resolved electron microscopy aims at tracking nanoscale excitations and dynamic states of matter with a temporal resolution ultimately reaching the attosecond regime. Periodic…
Point defect states emergence in a plasmonic crystal
Hikaru Saito, Hugo Lourenço-Martins, Noémie Bonnet +6
Plasmonic crystals are well known to have band structure including a bandgap, enabling the control of surface plasmon propagation and confinement. The band dispersion relation of b…
