Research Categories
Graeme Pleasance is currently a postdoctoral researcher in the Quantum@SUN research group. He graduated with an MSci in Theoretical Physics from the University of Birmingham (UK) in 2013, and received his PhD from the University of Sussex (UK) in 2018. From 2018 to 2022 he held a postdoctoral research position in the Quantum Research Group at the University of KwaZulu-Natal.
Research interests
Graeme’s research interests lie broadly in the theory of open quantum systems, quantum thermodynamics and quantum information. His research currently focuses on the development of non-perturbative techniques for treating strongly-coupled open quantum systems, with applications to thermodynamics. Additionally, he is interested in the fundamental characterization of quantum non-Markovianity and the role of decoherence in the quantum-to-classical transition.
