SUPERCONDUCTIVITY
Quantum point contact as a probe of a topological superconductor
Leiden University

"There have been many proposals lately on how to engineer topological superconductors using hybrid systems. Most of them are based on nanowires in proximity to an ordinary superconductor, with Majoranas at the ends of the wire."

"Unfortunately, such a measurement can only give an indication about Majoranas, but not strictly prove them."

"We propose to probe the Majoranas by coupling more strongly to the nanowire, namely via a quantum point contact."

PHOTONIC CRYSTALS
An azimuthally polarizing photonic crystal fibre with a central gold nanowire
Max Planck Institute for the Science of Light

"An azimuthally polarized beam maintains perfect zero intensity at the focal point, permitting a higher spatial resolution to be reached in stimulated emission depletion (STED) microscopy."

"In this work, we present a novel optical fibre based device that is able to filter an arbitrary polarized input beam such that only a donut-shaped azimuthal polarized beam remains."

NANOPLASMONIC STREAKING
Numerical simulation of attosecond nanoplasmonic streaking

"The nanoplasmonic field enhancement can have many applications. For example, it may be possible to develop laptop-sized high-repetition rate sources of coherent UV radiation by plasmon enhanced high harmonic generation."
