Cambridge Festival 2021 - Physics Researchers

A collection of short videos from current Cavendish researchers.

What is a Topological Insulator?

Dr Paolo Molignini

Dr Paolo Molignini is a theoretical physicist working as a Postdoctoral Research Associate at the University of Cambridge. His current research interests are nonequilibrium physics (driven-dissipative systems, Floquet engineering etc.), topological phases of matter, quantum optics and quantum simulation. He combines different theoretical techniques of many-body theory with numerical methods such as MCTDH-X, tensor networks, and exact diagonalization, and has also started to embed machine learning into his research.

Computational Physics: Understanding the Li-ion Battery

Angela Harper

Angela Harper is a current PhD student in the Theory of Condensed Matter Group at the Univeristy of Cambridge working with Dr. Andrew Morris. Her current work focuses on using crystal structure prediction techniques to identify new battery materials for higher-capacity Li-ion batteries. She hopes to identify materials which allow us to use rechargable batteries for grid-scale storage, electrified transport, and in conjunction with renewable sources of energy.

Photovoltaic and LED: Two faces of the same coin

Dr Denis Tihon

Dr Denis Tihon received the M.Eng. and Ph.D. degrees in physical engineering from the Université catholique de Louvain (UCLouvain), Louvain-la-Neuve, Belgium, in 2013 and 2018. During his Ph.D. he worked on the numerical modeling of periodic absorbers and partially coherent fields, in collaboration with the University of Cambridge. Between 2017 and 2019, he also worked on the simulation of magnetic resonance imaging (MRI) antennas in the context of M-Cube FET-OPEN European Project. Since 2019, he is holding a post-doctoral position, under the M. Sklodowska-Curie Fellowship, at the Cavendish Laboratory, Cambridge, where he is studying thermal and luminescent emitters.

New Materials for Optoelectronic Applications

Dr Amita Ummadisingu

Dr Amita Ummadisingu is a Swiss National Science Foundation Fellow at the Cavendish Laboratory. Her research interests are in sustainable energy technologies with focus on studying novel materials for opto-electronic applications which include solar cells, light emitting diodes (LEDs), photodetectors and lasers. She specializes in the formation of semiconductors from solutions for thin film devices. Her doctoral work at École polytechnique fédérale de Lausanne (EPFL) unravelled the formation of three-dimensional perovskite materials for the fabrication of highly efficient solar cells.

Her current project investigates the formation and opto-electronic properties of new two-dimensional perovskites. This highly interdisciplinary project combines aspects of Chemistry, Material Science and Physics to provide the vital foundation and toolkit for the design of highly efficient perovskite opto-electronic devices in the future. Beyond research, Amita is involved in outreach activities at the Cavendish Laboratory geared towards engaging schoolchildren in science.
