Paolo Molignini
Intro
We’re joined today by a familiar voice, Dr Paolo Molignini. Paolo will be leaving us soon, so this month we thought we would give a little insight into one of the people behind the podcast. Paolo is a postdoctoral research associate in the Theory of Condensed Matter group here at the Cavendish, bringing together elements of nonequilibrium physics, topological phases of matter, quantum optics and quantum simulation.
Born in Switzerland, he gained his BSc, MSc, and PhD in Physics from ETH Zurich before taking up a postdoctoral position in the Quantum Systems Engineering group at Oxford. His research involves developing several software applications for modelling quantum systems, including UNIQORN, which applies machine learning to model systems of ultra-cold atoms.
On top of this, Paolo has found time to contribute to several outreach programmes; producing a series of videos on superconductors during his time at Oxford, creating a doodle video on topological insulators for the first online Cambridge Science Festival, as well as hosting a monthly podcast looking at the people behind the physics research taking place at the Cavendish.
Today, we’ll talk about his experiences growing up in southern Switzerland, his path from Civil Engineer to Physicist, the work he does as a theoretician working in an experimental laboratory, and where this will take him next.
Stay with us…
Please help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time.
[00:36] – Guest’s intro
[02:02] – Current role at the Cavendish
[03:00] – More about Topological materials
[04:37] – Early interest in Science
[06:20] – Choosing Physics
[11:00] – Gravitating towards Condensed matter physics
[14:30] – Finding the PhD role and finding funding
[18:05] – In the news this month we talk about phase transitions. Whether we boil water or cook pasta, a phase transition is taking place. Matter can appear in many more different phases, some of which have an inherently quantum origin, such as superfluids or ferromagnets. While some of the classical phase transitions have been known for centuries, in recent years we have started to discover and study new exciting kinds of phase transitions at the quantum level which could be soon harnessed for incredible new technologies.
