In this talk I will present the case for using high-electric field, ultrashort femtosecond pulses of light to controllably switch the behaviour of topologically interesting systems such as the Dirac semimetal, graphene. I will also outline our research efforts in this space and why quasi-single cycle terahertz probe pulses provide a unique window into the dynamics and optical properties of Topological materials.
About the presenter
Gary Beane is a Research Fellow working with Dr Agustin Schiffrin at Monash University, where he is investigating optically driven topological phases of matter using terahertz time domain spectroscopy and ultrafast pump-probe spectroscopy. He is mainly involved in FLEET’s Research theme 2: exciton superfluids and Research theme 3: light-transformed materials.
