POST DOC POSITIONS

Available soon.

PHD POSITIONS

The PhD thesis will be hosted by Politecnico di Milano. They typically last for 3 years with possible starting in November, February and May. Applications need to be submitted enough in advance (typically a bit more than two months). The positions currently open are:

Attosecond dynamics in solids: from bulk to advanced 2D materials

Attosecond spectroscopy of solids is still in its infancy and its application to advanced materials is far from being trivial. Within this PhD thesis the Candidate will have to extend the known approaches to unconventional materials combining different pump-probe techniques with static measurements at synchrotron facilities. The main goal is to study exciton dynamics in 2D materials like transition-metal dichalcogenides. The candidate will also take part in the construction of the new polarization-invariant attosecond beamline. This position is funded by the ERC StG project AUDACE: http://www.audaceproject.it/

Circularly polarized attosecond pulses

The possibility to generate extreme-ultraviolet pulses with circular polarization and sub-fs time duration is at the frontier of Attosecond Science, enabling important and unprecedented applications. In the framework of this PhD work, the Candidate will have to investigate and implement different generation schemes for attosecond pulses of arbitrary polarization. After this, the candidate will employ these pulses to study ultrafast magnetic properties in solids where the underling physical mechanisms are poorly understood.

MASTER THESIS

We are looking for motivated master students to work in the following topics :
(further details can be found by clicking on the title)

Attosecond electron dynamics: from atoms to bio-relevant molecules
The temporal resolution provided by XUV attosecond pulses (1 as= 10-18 s) allows one to follow the electron dynamics in matter. The research activity at the basis of the thesis work is focused on the investigation of the ultrafast electron dynamics occurring in atoms and bio-relevant molecules.

Attosecond dynamics in solids: from bulk to advanced 2D materials
After the initial development in gas phase, attosecond spectroscopy techniques are now ready for application to condensed targets where fundamental physics questions related to the coherent response during light-matter interaction still remain unanswered.  In order to answer them, we need a probe capable to interview the sample with sub-femtosecond time resolution. Attosecond extreme-ultraviolet pulses represent the perfect tool to reach this goal.

Ultrafast UV-XUV spectroscopy: towards a complete study of DNA sub-units
DNA absorbs strongly photons in the harmful UV range (200-300 nm), which can potentially induced a photo-damage of the base sequence.  Nevertheless, the vast majority of excitations do not trigger photoreactions because the excess of energy after UV excitation is efficiently dissipated by DNA on ultrafast time scales (e.g. tens of femtoseconds for the nucleobases). This thesis is focused on the development of an innovative UV beamline to track the fundamental physical processes in DNA subunits occurring in the first few femtoseconds after UV excitation.
