Symmetry in Crystal Structure Prediction

Autor: Darby, James

Over the past few decades, advances in computing power and the continued development of efficient modelling techniques, capable of providing chemical accuracy, have made in silico crystal structure prediction (CSP) a reality. Armed with this powerful

Theoretical studies of compressed xenon oxides, tin selenide thermoelectrics, and defects in graphene

Autor: Worth, Nicholas Gower

Enormous advances in computing power in recent decades have made it possible to perform accurate numerical simulations of a wide range of systems in condensed matter physics. At the forefront of this progress has been density functional theory (DFT),
