HEAD OF THE LAB
My scientific background is in the fields of condensed matter physics, ultrafast laser spectroscopy, and quantum optics. My past activities, mainly experimental, range from non-linear photoemission processes from metal surfaces, static studies of transition metal oxides and correlated electron systems, time-resolved spectroscopic techniques and ultrafast laser technology. I have a good familiarity with both table top spectroscopic techniques and synchrotron (or Free Electron Laser) based experiments. More recently I focused on quantum state reconstruction techniques for ultrashort light pulses. The major scientific achievements of my career up to now have been the development of a unique spectroscopic tool capable of measuring the time evolution of the spontaneous Raman response following laser excitation, the optical control of superconductivity in the cuprates, and the discovery of an ultrafast dressing of subgap excitation in in insulating transition metal oxides.
Bachelor’s degree in Physics (2015) and Master degree in Condensed Matter Physics (2017) and PhD (2020) at the University of Trieste with supervisor Daniele Fausti.
My present research activity investigates the ultrafast dynamics of electronic and phononic degrees of freedom in complex materials, in particular transition metal oxides, performing pump-probe spectroscopy experiments. Focus is set on the analysis of quantum statistical observables in the optical probe, using multimode shaped homodyne detection.
I earned my Bachelor degree in Physics in 2012 and my Master degree in Condensed Matter Physics in 2015. During my PhD I worked on two main topics: high temperature superconductivity, and in particular on the observation of superconducting features above the critical temperature, and the interpretation of photon number fluctuation measurements in time resolved spectroscopy. In 2019 I defended my PhD thesis with title Intensity and Fluctuation dynamics in pump probe experiments in complex materials.
My actual research is focused on out-of-equilibrium experiments on strongly correlated systems, especially cuprates, both with “standard” pump-probe spectroscopy and time resolved single pulse statistics.
I obtained a Bachelor degree in Physics (University of Trieste, 2016) and a Master degree in Condensed Matter Physics (University of Trieste, 2018). I am currently involved in a PhD program at the University of Trieste in collaboration with Elettra Sincrotrone Trieste S.C.p.A. working in the field of ultrafast optical spectroscopy. My research interests focus on studying and controlling quantum properties of complex materials exploiting light-matter interaction. In particular, I have designed a novel pump-probe setup combining visible and mid-infrared sources to selectively excite electronic and phononic degrees of freedom and thus address their coupling in complex systems.
Shahla Yasmin Mathengattil
I did my bachelor and master degree at IISER Thiruvananthapuram, India (2020). The work I was pursuing during my master thesis revolved around the investigation of charge density wave dynamics and nonlinear properties of strongly correlated cuprate system using high intense terahertz radiation. Currently I am enrolled as a PhD student at University of Trieste under the supervision of Daniele Fausti. My research focuses on analyzing the properties of a quantized electromagnetic field and an atomic system coupled together. The cavity coupled molecules are studied by analyzing the emission from the photonic cavity.
Master student in Condensed Matter Physics with a thesis on “Multimode homodyne detection applied to time-resolved Raman spectroscopy”. Current PhD student in Physics (2019-) under the supervision of Prof. Daniele Fausti. My research interests involve the experimental investigation of coherent quantum dynamics in solid state systems, combining non equilibrium spectroscopies in low noise regime and pulse shaping techniques.
Enrico Maria Rigoni
I earned a Bachelor’s degree in Physics (2018) and a Master degree in Condensed Matter Physics (2020), both at the University of Trieste. At the moment, I’m enrolled in a PhD program at the University of Trieste under the supervision of prof. Daniele Fausti. My current research activity explores ultrafast excitation dynamics in complex materials by means of pump-probe experiments. In particular, I employ multimode heterodyne detection to access quantum noise regime and hence to perform a full reconstruction of the probe pulse quantum state.
