Light at optical frequencies interacting with a metal surface can excite interband quantum
transitions, or intraband currents at frequencies approaching the PHz range. Momentum …

In this work, we use optical reflectance spectroscopy to study the plexciton formation
between Ag nanoclusters and C 60 molecules. The Ag clusters are fabricated on high …

Exploring the quantum effects in plasmonic responses has attracted growing interest during
the past decade. Extreme downsizing of nanoparticles and interparticle gaps is promising for …

Strong coupling between vacuum fields and quantum matter occurs at the nanoscale and
broadens the horizon of light-matter interaction. Nanoscale Casimir force, as an exhibition of …

In a slab geometry with large surface-to-bulk ratio, topological surface states such as Fermi
arcs for Weyl or Dirac semimetals may dominate their low-energy properties. We investigate …

A topologically equivalent tight binding model is proposed to study the quantum phase
transitions of dimer chain driven by an imaginary alternating field. I demonstrate how the …

In the remaining part, I will focus on recent results which regard epitaxial graphene and
hexagonal boron nitride (hBN) engineering by the adsorption and intercalation of atomic …
