Project Mercator, T1, E3

Surface optical spectroscopy of phonon and electron excitations in quasi-one dimensional metallic nanostructures; and Ground- and excited-state properties of substrate-supported nanowires calculated from first principles

Areas of Research

• Theory of optical properties of surfaces and interfaces

• Ab initio computation of excited states in low-dimensional systems

• Application of many body techniques to light-induced degradation in artworks
