SERGIO LUCIO DE BONIS ’Spin Detection Using a Carbon Nanotube Mechanical Resonator’

Micro-scale mechanical resonators are highly sensitive force sensors, enabling the detection of very small ensembles of nuclear spins. Recently, our group showed that mechanical resonators made of suspended carbon nanotubes display outstanding properties, such as quality factors up to 5 million, and force noise as low as 10-21 N Hz-1/2. We propose to use this excellent sensitivity capability to detect and manipulate the nuclear spins of the 13C atoms naturally present in the carbon nanotube. In this seminar I will explain our strategy to carry out the measurement, showing some ideas and the current status of the experiment.


NICOLA DI PALO ’Unraveling Electrons’ Motion With Attosecond X-Ray Light Flashes’

Most of the spectacular phenomena determining the world around us are ruled by electrons’ behaviour. Electrons control, for example, the formation and breaking of chemical bonds in molecules, the conducting or insulating behavior of materials, or their magnetic features. Improvement and control over these phenomena relies on our capability to study electrons and their motion, following on their native ultrafast timescale, the attosecond (10-18 s) temporal regime. Necessary tools are ultrashort light pulses (on the scale of 10-100 as) in an energy range spanning over the extreme ultraviolet and soft X-ray regions such that they can access the specific elements’ fingerprints under investigation. In this seminar I will present the main results achieved by the group on the generation of such light pulses and the possibility to use them for probing electron dynamics, central topic of my investigation.
