Interest in linear and nonlinear optical spectroscopy at surfaces and of nanostructures. For simultaneous spatial information we explore new routes for ultrahigh resolution optical imaging far beyond the diffraction limit. Topics include single molecule spectroscopy, surface photochemistry, molecular plasmonics as well as surface electron dynamics and electron-phonon interaction.

Fabian Menges

Branco Weiss Fellow
fabian.menges@colorado.edu

Investigates the elementary steps of thermodynamic processes in quantum materials and molecules, by developing thermo-plasmonic nano-imaging and spectroscopy technique with spatio-temporal resolution down to the nanometer-femtosecond scale. Interested in the thermalization of molecular structures, the emergence of dissipative structures in strongly correlated materials, local thermoelectric effects in topological materials, phononic control of quantum phases, caloric effects in ferroic materials, polariton transport in van der Waals-layered materials.
