Friday Seminar: Manipulating and Controlling Spin-Photon Hybridisation Speaker: Rair Macêdo, University of Glasgow, UK

In recent years we have witnessed a growing interest in cavity-magnon-polaritons (CMPs). These are hybrid light–matter quasiparticles originating from strong coupling between magnons and cavity photons. It is expected that by combining light and magnetism in such way, it should be possible to also combine quantum information with spintronics. This emergent phenomenon can also be employed to engineer devices including, gradient memory and radiofrequency-to-optical transducers. In order to enable more functionality in CMPs, it is particularly interesting to engineer and understand the coupling strength between elements of a hybrid system – a property which works as a measure for coherent information exchange. In this talk, I will discuss the importance of the field configuration within the cavity and how different polarisation states can affect the behaviour of cavity magnon polaritons and how those can ultimately be coherently controlled in time.

About the speaker:

Dr Rair Macêdo is a theoretical physicist by training—but every so often dabbles in the world of experimental physics. He started pursuing research at the age of 16, as a part of his BSc studies, in the area of novel optical effects in natural hyperbolic media. After receiving a PhD in physics from the University of Glasgow in a similar area, but at an advanced theoretical level, modelling electromagnetic properties of magnetic structures, he held a Leverhulme Trust Early Research Fellowship to develop novel metamaterials to control and manipulate electromagnetic waves. He is currently a Senior Lecturer in Electrodynamics and Spin Electronics at the Electronic & Nanoscale Engineering Division of the James Watt School of Engineering, University of Glasgow.
