Our lab is interested in the exploration of physical phenomena and interactions at the nanoscale in quantum materials, using advanced nano-optical spectroscopy and imaging techniques across a wide spectral range from visible to terahertz frequencies, with diffraction-unlimited spatial resolution. We are broadly interested in non-equilibrium phenomena in physical systems and are particularly fascinated by how non-equilibrium or collective quantum effects at the atomic/molecular scale give rise to nanoscale emergent behavior.
