Ion microscopy based on laser-cooled cesium atoms
M. Viteau, M. Reveillard, L. Kime +11
We demonstrate a prototype of a Focused Ion Beam machine based on the ionization of a laser-cooled cesium beam adapted for imaging and modifying different surfaces in the few-tens…
Local mechanical properties of electrospun fibers correlate to their internal nanostructure
Andrea Camposeo, Israel Greenfeld, Francesco Tantussi +6
The properties of polymeric nanofibers can be tailored and enhanced by properly managing the structure of the polymeric molecules at the nanoscale. Although electrospun polymer fib…
Photoionization spectroscopy of excited states of cold cesium dimers
Nadia Bouloufa, Elena Favilla, Matthieu Viteau +8
Photoionization spectroscopy of cold cesium dimers obtained by photoassociation of cold atoms in a magneto-optical trap is reported here. In particular, we report on the observatio…
Defect Induced Photoluminescence from Dark Excitonic States in Individual Single-Walled Carbon Nanotubes
Hayk Harutyunyan, Tobias Gokus, Alexander A. Green +3
We show that new low-energy photoluminescence (PL) bands can be created in semiconducting single-walled carbon nanotubes by intense pulsed excitation. The new bands are attributed…
Efficient formation of deeply bound ultracold molecules probed by broadband detection
Matthieu Viteau, Amodsen Chotia, Maria Allegrini +4
Using a non-selective broadband detection scheme we discovered an efficient mechanism of formation of ultracold Cs molecules in deeply bound levels () of their electroni…
Optical pumping and vibrational cooling of molecules
Matthieu Viteau, Amodsen Chotia, Maria Allegrini +4
The methods producing cold molecules from cold atoms tend to leave molecular ensembles with substantial residual internal energy. For instance, Cs2 molecules initially formed via p…
