Attosecond nanoscale near-field sampling

open access: yesNature Communications, 2016
Photoemission from nanometre-scale structures offer a route toward ultrafast light-field-driven electronic nanocircuits. Here, the authors use attosecond streaking spectroscopy for nanoscale characterization of near-fields in the vicinity of tapered gold

Autler–Townes splitting in the trap-loss fluorescence spectroscopy due to single-step direct Rydberg excitation of cesium cold atomic ensemble

open access: yesAIP Advances, 2023
We experimentally investigate trap-loss spectra of the cesium 6S1/2(F = 4) → 71P3/2 Rydberg transition by combining the cesium atomic magneto-optical trap with the narrow-linewidth, continuously tunable 318.6 nm ultraviolet laser. Specifically, the atoms

Establishing and storing of deterministic quantum entanglement among three distant atomic ensembles

open access: yesNature Communications, 2017
Continuous-variable encoding is a promising approach for quantum information and communication networks. Here, the authors show how to map entanglement from three spatial optical modes to three separated atomic samples via electromagnetically induced ...

Collision models in quantum optics [PDF]

open access: yes, 2017
Quantum collision models (CMs) provide ad- vantageous case studies for investigating major issues in open quantum systems theory, and especially quantum non-Markovianity. After reviewing their general de nition and distinctive features, we illustrate the
