The goal of my research is to develop a quantitative understanding of the stationary states and dynamic properties of electrons at surfaces, interfaces, and nanostructures. This work involves new theoretical concepts and techniques, simple models to elucidate basic physics, and computational work to accurately solve the equations of quantum theory. Current topics of interests include:


Dynamics of surface excitations

I study electronic states at metal surfaces, with a focus on the dynamics of excitations in surface bands whose femtosecond lifetimes reveal a wealth of key quantum physics, such as electron-electron scattering, screening, interactions with lattice vibrations. A particular focus is lifetime signatures in scanning tunneling spectroscopy, using ab-initio DFT codes, Green functions scattering models and many-body GW theory.

Surface nanostructures


Nanoscale structures occupy the regime between atomic-like systems and extended solids, exhibiting strong interplay between structural dimensions and physical properties and with it the potential for novel behaviour. I am interested in the quantum physics of supported nanostructures using electronic structure methods to study the consequences of quantum confinement, substrate coupling and the use of nanostructures as quantum laboratories.


Variational embedding

I am interested in the development and application of variational embedding methods for electronic structure problems, including quantum confined systems, surfaces coupled to extended substrates, and for studying transport through nanostructures. I am also interested in the extension of variational embedding theory to the equations of relativistic quantum theory.
