Characterisation of Nanoparticle Size Distributions in a Fluid using Optical Forces

Kiana Malmir, William Okell, Aurélien A P Trichet +1

We introduce a method for analyzing the physical properties of nanoparticles in fluids via the competition between viscous drag and optical forces. By flowing particles through a m…

Non-adiabatic ponderomotive effects in photoemission from nanotips in intense mid-infrared laser fields

Johannes Schötz, Sambit Mitra, Harald Fuest +10

Transient near-fields around metallic nanotips drive many applications, including the generation of ultrafast electron pulses and their use in electron microscopy. We have investig…

Attosecond physics at the nanoscale

M. F. Ciappina, J. A. Pérez-Hernández, A. S. Landsman +22

Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pu…

Attosecond nanoscale near-field sampling

Benjamin Förg, Johannes Schoetz, Frederik Suessmann +15

The promise of ultrafast light field driven electronic nanocircuits has stimulated the development of the new research field of attosecond nanophysics. An essential prerequisite fo…
