Speaker: Dr Fabio Novelli

On the 10th of June we will have a talk from Dr Fabio Novelli. The title of Dr Fabio Novelli’s talk is: “Terahertz and Water”. The full details of the talk are below.

An inherently powerful tool to study liquid water is terahertz (THz) radiation because it can reveal the sub-ps fluctuations of the water network: radiation between about 1 and 25 THz is strongly  absorbed by intermolecular collective modes of hydrogen-bonded water molecules, which can be thought of as “small and short-lived phonons”. The talk is divided into two parts. In the first part he will describe a novel approach, dubbed “intense THz time-domain spectroscopy”, to probe the subtle variations of the water modes due to the interaction of the liquid molecules with different solutes [1]. In the second part, he will discuss how to trigger and detect photo-ionization processes in pure water and salt solutions, that is, how liquid water responds to additional excess charge carriers like electrons [2-4].

Speaker bio: Fabio Novelli earned his PhD in nonlinear optics and condensed matter Physics in 2013 from the University of Trieste (Italy) under the supervision of Fulvio Parmigiani and Daniele Fausti. From 2014 to 2016 he worked on multidimensional coherent effects in light-harvesting proteins with Jeff Davis at Swinburne University, Australia. From 2017 to 2022 he investigated aqueous solutions with Martina Havenith at Ruhr University, Germany. Since 2023, he has been Principal Investigator on an Individual Research Grant (DFG) exploring the conductivity of gold nanoparticles suspensions. He was recently appointed as Associate Professor in Physics at the University of Southampton, UK.
